the mrna molecules used in the moderna (mod) and the pfizer-biontech (p-tech) vaccines contain genetic information for what sars-cov-2 viral component?

Answers

Answer 1

The mRNA molecules used in the Moderna (mod) and the Pfizer-BioNTech (p-tech) vaccines contain genetic information for the Spike protein of the SARS-CoV-2 viral component

A protein that emerges from the enveloped virus's surface in the form of a large structure known as a spike or peplomer is referred to as a spike protein or peplomer protein.

Moderna and Pfizer vaccines are based on mRNA and contain genetic information for spike protein. This allows the body to develop immunity to spike protein and defend itself against viral infection.

The Spike protein of SARS-CoV-2 binds to the receptor on the host cell and causes virus-cell membrane fusion, which is essential for the virus's invasion.

what are start and stop codons? what are insertion, deletion, and substitution mutations? what are frameshift, missense, nonsense, and silent mutations? which type of mutation is most likely to cause a change in a protein's structure and function (frameshift, missense, nonsense, and or silent mutations)? what is least likely to change the protein's structure and function? explain.

Answers

The start codon identifies the location where the translation of a protein sequence starts, and the stop codon identifies the location where translation ends.

what are start and stop codons?

The start codon is the first group of codons in an mRNA transcript that a ribosome translates. The most frequent start codon for methionine in eukaryotes is AUG.

A protein translation process is to be stopped by the stop codon, which is a termination codon. The amino acid chain is broken by this codon because it separates the ribosomal subunits. The common stop codons are UAG, UAA, and UGA.

A mutation is a change in a genome's base pairs or nucleotide sequence.

Substitution

A nucleobase gets changed for another one in this particular type of mutation. Point mutations or nucleotide substitutions are the results.

Insertion

Nucleotides are added to or inserted into the DNA sequence in this particular sort of mutation. Frameshift mutation results from it.

Deletion

The nucleotides are deleted or removed from the sequence in this particular sort of mutation. Frameshift mutation results from it.

Silent mutations happen when one DNA nucleotide changes within a gene's protein-coding region without changing the sequence of amino acids that make up the gene's protein.

If nucleotide bases are added or removed from a gene in amounts that are not multiples of three, this is referred to as a frameshift mutation. This is significant because, when creating a protein, a cell reads the genetic code of a gene in groups of three nucleotides.

miss sense mutation is a genetic change wherein a single base pair substitution modifies the genetic code in a way that results in the production of an amino acid that differs from the typical amino acid at that place.

Non sense mutation -genetic modification that causes a protein to end prematurely. The altered protein may be changed or lose its function as a result of partial or complete inactivation.

A frameshift mutation will almost certainly alter the protein's structure and function.

Silent mutations: A few mutations that alter DNA bases have no impact on the order of the amino acids in a protein. Because the amino acid sequence is unaffected, these changes, also known as silent mutations, have no impact on the protein's structure or functionality.

What happens to the chemistry of the seawater as more co2 is absorbed into the oceans?.

Answers

The concentration of hydrogen ions increases as a result of a series of chemical reactions that take place when CO2 is absorbed by saltwater.

As more CO2 is absorbed by the seas, what happens to the chemistry of the seawater?

More carbon dioxide is evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide concentrations. Currently, the ocean has an average pH of 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean turns more acidic.

What happens to seawater that has absorbed CO2?

Rapid oceanic absorption of carbon dioxide (CO2) results in ocean acidification. It creates carbonic acid by a reaction with water molecules (H2O) (H2CO3). After that, this molecule decomposes into bicarbonate and a hydrogen ion (H+) (HCO3-). These hydrogen ions lower the pH of the ocean.

C. impermeable to water and permeable to sodium.

Anatomy of Loop of Henle -

The loop of henle is a tubular extension of proximal convulated tubule. It is hair pin like structure consisting of a descending and an ascending loop. The loop of henle lies in close proximity to the peritubular network called vasa recta. The ascending and descending loop are themselves divided into a thick segment and thin segment. Majority of the loops of henle lie in the medullary region of the kidney.

Physiology of Urine formation in Loop of Henle -

Different segments of loop of henle have different permeability to sodium and water. As the tubular contents pass through descending loop the urine becomes hypertonic dur to selective absorption of water. While passing through the ascending segment the loop of henle selectively allows absorption of sodium due to its permeability. It leads to more and more absorption of sodium without absorption of water leading to hypotonicity of the urine. This permeability difference is favored by the counter current mechanism between the tubular flow and blood flow in vasa recta.

So the ascending portion of loop of henle is impermeable to water and permeable to sodium.
