The controlled timing of gene expression is crucial to an organism because it allows for differentiation, specialization, and development. Thus, the correct option is D, i.e. all of the above.
What is Gene expression?Gene expression may be defined as a process through which a cell utilizes several functional gene products to synthesize RNA and then functional proteins.
Gene expression mediates the process of differentiation and specialization of all functional proteins that are synthesized at particular target sites.
The completion of gene expression also allows the cell to divide functionally and provokes the growth of cells to facilitate development.
Therefore, the correct option for this question is D.

what are four different types of bases in DNA and how do they pair?
Answer:
Adenine, Thymine, Guanine, and Cytosine
They possess complimentary paring. Meaning the one will only bind another, and will not bind with and other one
Explanation:
DNA has four types of bases, such as adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine forms double hydrogen bonds with thymine, while guanine forms triple hydrogen bonds with cytosine.
What is the composition of the DNA?
DNA is called deoxyribonucleic acid. It is a polymer of nucleotides. Each nucleotide is made up of a phosphate, a pentose sugar, and a nitrogenous base. In DNA, there are four types of nitrogenous bases, such as adenine (A), guanine (G), cytosine (C), and thymine (T).
Adenine and guanine are purines and double-ringed structures. Cytosine and thymine are pyrimidines and single-ringed structures. A purine forms a bond with a pyrimidine. Adenine (A) forms a double hydrogen bond with Thymine (T), and Guanine (G) forms triple hydrogen bonds with Cytosine(C).
Hence, in DNA, four nucleotides are found: adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine pairs with thymine, while guanine pairs with cytosine.

The atomic mass of arsenic is 75 atomic mass units; a neutral atom of asennic has 33 electrons. how many neutrons does arsenic normally have?
a.33 b.42 c.75 d.108
Answer:
42
Explanation:
Atoms have a neutral charge overall, which means they have an equal numbers of positively-charged protons and negatively-charged electrons. Here, an atom of arsenic with 33 electrons must also have 33 protons.
The mass of any atom is contained in its nucleus, a part made up of protons and neutrons - particles with no charge. Both protons and neutrons are exactly 1 atomic mass unit each, so to find the atomic mass of an atom, we can use the formula
(# of protons) + (# of neutrons) = atomic mass
or equivalently:
atomic mass - (# of protons) = (# of neutrons).
For arsenic, we have an atomic mass of 75 amu and 33 protons, so using our formula:
# of neutron = 75 - 33 = 42 neutrons

O 1, 2, and 3 O 1,2, and 5 O 2,3, and 4 O 2,3, and 5
Answer:
1, 2, and 5
Explanation:
Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.
As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.
Based on this information, we can see that the correct statements are statements 1, 2, and 5.

Which describes a group of organisms that are members of a species?
Answer:
They can breed and produce offspring that can breed.
Explanation:
The options you were given are the following:
They can breed and produce offspring that can breed. They are members of the same community. They live in the same ecosystem, community, and biome. They have similar physical characteristics.A species can be defined as a group of similar organisms that can reproduce and produce offspring that can produce as well. This is why the first option is the correct one.
In ecology, the term community refers to a group of populations of two or more different species that inhabit the same area. More than one species can be found in a biome and ecosystem as well, which is why the second and third options are incorrect.
Some organisms can look very similar but belong to different species. This is why the fourth option is not correct, either.

how does messenger rna work inside the cell
Answer:
A RNA polymerase separates the hydrogen bases of a gene to produce a strand of messenger RNA, which leaves to nucleus. When a ribosome attaches itself to the messenger RNA, it reads the RNA 3 bases at a time to build amino acids which are then folded into proteins.
More explained process:
Note: The description below will explain the process of “protein synthesis”, in which the mRNA (messenger RNA) takes part of.
In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids. [ For example, the bases are AUC, the corresponding amino acid will be isoleucine (Ile). Next, the tRNA molecules carry the amino acids to mRNA, reads the RNA 3 bases at a time to build an amino acid chain which are then folded into proteins.

17. C " TAAGCTG". It would be the replication strand because A always pairs with T and C always pairs with G, so replication strands just have the opposite base as the original strand
18. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
19. Straight hair is controlled by a recessive allele because as you can see the one where is not shaded is the one that has the most. There are only 1 shaded circle or square, out of the 12 other circles or square that is not shaded.

Answer:
No
Explanation:
The universality of the genetic code refers to how the codons for amino acids are always the same in almost all species. Amino acids have corresponding nitrogenous bases in pairs of three called a codon. so to have the same amino acids, all species would need the same nitrogenous bases.
