Protein

Proteins are the most versatile macromolecules in living systems and they play important roles in essentially all biological processes. Protein makes up the capsid of a virus. The infective extracellular form of a virus known as a virion contains at least one unique protein synthesized by specific genes in the nucleic acid of that virus. In almost all viruses, at least one of these proteins forms a shell (called a capsid) around the nucleic acid. Certain viruses also have other proteins internal to the capsid. Some of these proteins act as enzymes during the synthesis of viral nucleic acids.

Need a hypothesis for “How are proteins built from RNA”
Dima020 [189]

Hi!


Hypothesis:

<em>Proteins are built from the translation of messenger RNA (mRNA) molecules</em>


RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).


<h3><u>From DNA to RNA</u></h3>

RNA is generated through transcription of the DNA molecule, resulting in a <em>complementary </em>molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA    <em>(complementary with U instead of T)</em>


<h3><u>From RNA to Protein</u></h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon <em>UCA</em>, the tRNA will allocate a <em>Serine residue.</em>

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.


Hope this helps!

This is an excerpt from "When We Two Parted" by Lord Byron.
Diano4ka-milaya [45]
The main theme of the poem is the regret and sorrow the narrator feels about the end of his relationship with the woman in the poem, described only as "you." The poem suggests that the woman may well have been the one to break off the affair: Pale grew thy cheek and col

Vinil7 [7]

Disruptive selection or diversifying selection describes the changes in population genetics where extreme values for a trait are favored over intermediate values.

So according to this definition, the conclusion can be derived as :

The most common circumference(s) to be after 10 generations of diversifying selection will be greater than 2 cm and less than 2 cm.
