The statements that are true regarding transcription and translation in prokaryote

Prokaryotes and eukaryotes both engage in transcription and translation; but, in eukaryotic cells, these processes occur at distinct locations than in prokaryote cells Prokaryotic cells do not go through the considerable processing that occurs in eukaryotic cells before the mRNA is prepared for translation.Transcription and translation are independent processes that happen in eukaryotic cells; transcription happens in the nucleus, while translation happens in the cytoplasm. Transcription and translation are ongoing processes in prokaryotic cells that both take place in the cytoplasm. Prokaryotes but not eukaryotes have continuous transcription and translation processes.

Each of the species concepts (morphospecies, biological, and phylogenetic) have strengths and weaknesses. Compare and contrast all three, and evaluate them for their relative usefulness.

Answers

Morphospecies: A species that only differs from others in terms of morphology.

Strength ;

Differences in physical characteristics serve as the basis for defining species.species are simpler to distinguish because they are regarded as species if several organisms share a similar appearance.because it is a simpler approach to categorize organisms.

Weakness ;

Quite subjective, thus it might be difficult to decide which characteristics to use to identify a species.There is no thought given to reproduction or reproductive seclusion.Errors might arise while identifying species if morphological characteristics are not clearly visible, remain in an immature form, or are damaged.

Biological : Biology-related or having to do with life and living things. refers to a material created from a living thing or one of its byproducts in medicine. Biologicals can be used to treat, diagnose, or relieve disease symptoms.

Strength ;

species distinguished by uniqueness.Populations make up species rather than isolated individuals.isolated populations in terms of reproduction.In this case, species serve as both an ecological and genetic unit. In its surroundings, the species as a whole interacts with other species. It is a genetic unit that functions as a gene pool, and each person is in possession of a fraction of that gene pool.Species are reproductive groups where members identify potential partners for reproduction.

Weakness ;

Only applies to creatures that reproduce sexually.species that are not distinguished by any outward features.This concept cannot be used to evaluate hybrid complexes.

Phylogenetic :

The study of evolutionary relationships among biological things, most frequently between species, people, or genes, is known as phylogenetics (which may be referred to as taxa).

Strength ;

The smallest group of individuals within whom a parental pattern of ancestry and descent is discernible is referred to as a species in this context.Each species needs to be distinct from every other species.Diagnostic traits that can be used to categorize reproductive communities must be passed down from one generation to the next.The species, or group of people, must not contain any other exclusive groups.

Weakness ;

Removing reproductive isolation as a factor in species classification.Recognizes any character, not only morphological ones, as being appropriate for diagnosis.Many species that are recognized by other concepts are not taken into account.

Evaluation:

According to the comparison above, adopting the morphological or morphospecies notion is the simplest method to identify a group as a species.

If conditions are favorable, all features must be clearly visible and undamaged, all organisms must be of the same age group or close to it, and the characteristics to be used as characters for differentiating must be pre-specified or pre-determined by researchers

2. The phylogenetic species idea is useful for tracing ancestry since it recognizes species as the smallest collection of people who share a common ancestor.

But given the removal of reproductive isolation or patterns, as well as the non-use of morphological traits, this is completely undesirable.

3. The biological species notion is the one that is most widely recognized. Because it recognizes the reproductive system and declares that a population, rather than a collection of unrelated or disconnected organisms, constitutes a species.

This general observation fits quite well with the statement of this concept, namely that species serve as genetic and ecological units. We can observe normally that one species interacts with another species even after being isolated (reproductively), and that the species also serve as a reservoir of genes. In light of all of the information, we can say that the idea is viable and likely to produce positive outcomes.

chemoreceptors . chemoreceptors . are present in the carotid bodies provide information on blood pressure to cardiovascular and respiratory control centers consist of free nerve endings that branch within the elastic tissues in the walls of hollow organs monitor changes in pressure

Answers

Chemoreceptors. One way to control breathing is through feedback from the chemoreceptors. There are two types of respiratory chemoreceptors.

While peripheral chemoreceptors act faster because they detect changes in the periphery such as air/oxygen pressure. When there is a partial pressure of oxygen. The chemoreceptors of the cardiovascular system are located in two places. The carotid bodies are located in the carotid arteries that run through the neck to the brain, and the aortic bodies are located in the aortic arch, an arterial feature near the heart. They have main functions in respiratory regulations and gustatory and olfactory sensory reactions. A trigger for peripheral chemoreceptors is hypoxia, or reduced oxygen levels in the body due to high altitudes, etc. This stimulates the carotid and aortic bodies to signal to the brain that it needs more oxygen.

Answers

Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

In general, mRNA  carries the genetic material from the DNA to the cytoplasm, where translation occurs. In the process of translation, proteins are made by utilizing the  information stored in the mRNA sequence. These mRNA are attached to a structure called a ribosome these are able to read the genetic information.

On the other hand, Transcription occurs in the nucleus in eukaryotic organisms, while translation is said to take place in the cytoplasm and endoplasmic reticulum.

Explain the relationships between the following terms: DNA, chromosomes, sister chromatids,
homologous chromosomes and replicated chromosomes.

Answers

Answer:

DNA is the genetic material that is organized into genes and located on chromosomes.

Chromosomes are replicated during cell division, producing sister chromatids.

Humans have 23 pairs of homologous chromosomes, and each pair is composed of one chromosome inherited from the mother and one chromosome inherited from the father.

Sister chromatids are identical copies of replicated chromosomes that are joined together at the centromere.

Answers

Sepsis is a result of a failure of the body's mechanisms and usually is usually caused by gram negative bacteria.

The body's severe response to an infection is sepsis. It's a medical emergency that could endanger life. When an infection you already have sets off a series of events throughout your body, it results in sepsis. Sepsis-causing infections typically begin in the gastrointestinal system, urinary tract, skin, or lungs.

Answers

A(n) operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.

An operon is a functional piece of DNA in genetics that houses a collection of genes that are all regulated by the same promoter. The genes are combined during transcription to form an mRNA strand, which is then either translated in the cytoplasm as a single unit or split into monocistronic mRNAs, which are translated individually and consist of many strands of mRNA that each encode a single gene product. The operon's genes as a result either express themselves simultaneously or not at all. An operon is defined by the co-transcription of many genes.

There is a 50% chance that they will have a heterozygous offspring.

What is a trait and how to find out the possibility of heterozygous offspring using a cross?

A trait is a characteristic or feature of an organism that can either be modified by the environment or expressed genetically. Genes, environment, or a combination of the two may affect traits. Qualitative and quantitative qualities both exist. An unchangeable constant passed down from parent to child at birth is known as a characteristic.

Now, for a cross with four offspring, it is given that-

Male cat- AA Bb

Female cat- aa bb

Cross: AA Bb × AB

From Punnett square, gametes are- AB, Ab, and ab AaBb ab ab Aabb

The trait probability for a heterozygous trait is either 1 or 100%.

Half, or 50%, of individuals have the heterozygous b trait.

50% = 50% is the total probability.

Therefore, the probability that the cats will have a heterozygous offspring is 50 %.
