Specialized structures are expressed with the help of mRNA. What role does mRNA play?

Answers

Answer 1

It is true that specialized structures are expressed with the help of mRNA and it's role is described below.

mRNA are the type of RNA found in cells. messenger RNA molecules carry the genetic info required to form proteins. They carry the data from the DNA within the nucleus of the cell to the protoplasm wherever the proteins are created. conjointly referred to as ribonucleic acid.

The role of messenger RNA is to hold macromolecule info from the DNA in an exceedingly cell's nucleus to the cell's protoplasm (watery interior), wherever the macromolecule-making machinery reads the messenger RNA sequence and interprets every three-base sequence into its corresponding aminoalkanoic acid in an exceedingly growing protein chain. This molecule (mRNA) is a nexus between DNA and proteins.

How does mutation affect transcription?

When DNA harm in the transcribed strand of an active gene is bypassed by an RNA polymerase, it can miscode at the destruction site and produce mutant transcripts.

This procedure known as transcriptional mutagenesis can lead to the production of mutant proteins that could be important in tumor development.

The rate of transcription for a gene is found to be affected by a mutation found in the promoter region for the gene.

Why is transcription affected by mutation?

Hereditary disorders are typically brought on by genetic changes that alter the structure of the transcribed mRNA and the protein that it encodes, making the mRNA and/or protein unstable. However, these mutations can occasionally have comparable devastating effects on the synthesis, processing, or translation of the mRNA.

An RNA polymerase may miscode at the point of DNA synthesis and generate mutant transcripts if DNA damage in the transcribed strand of an active gene is ignored. The process of transcriptional mutagenesis can produce mutant proteins that may have a role in the growth of tumors.

What is pleural membrane?The pleura membrane is a serous membrane that folds  on itself to form a two-layered membranous pleural sac.The outer layer is known as the parietal pleura and attaches to the chest wall. The inner layer, called the visceral pleura, covers the lungs, blood vessels, nerves, and bronchi. The pleura membrane consists of two thin layers of tissue that protect and cushion the lungs. The lining (the visceral pleura) wraps around the lungs and adheres to the lungs so that it does not peel off. The outer layer forms the inside of the chest wall.

Answers

Fahrenholz' rule states that the evolutionary history of a parasite will mirror that of its host only if there is no reciprocal selection.

Authors, such as Kellogg and Fahrenholz, observed that closely related host species were associated with closely related avian parasites that shared similar phenotypic characteristics. The Fahrenholz rule, which they proposed in 1913, states that a parasite's phylogeny "mirrors that of its host." Therefore, option B is the right choice.

Some time later, in 1940, Szidat put forth a similar idea: "Primitive hosts harbour primitive parasites." The theory put forth was that co-speciation—the concurrent and interdependent bifurcation of host and parasite lineages—causes similarity between the parasites of related hosts, which in turn results in congruent host and parasite phylogenies.

Moreover, mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division. Mitosis is generally followed by equal division of the cell's content into two daughter cells that have identical genomes.
