Each cell expresses, or turns on, only a fraction of its genes. the rest of the genes are repressed, or turned off. the process

of turning genes on and off is known as gene regulation. gene regulation can occur at any point during gene expression, but most commonly occurs at the level of _________, when the information in a gene's dna is transferred to mrna.

Answer: the correct answer is "transcription"

Explanation: Gene regulation is the process of activation and deactivation of genes. In the early stages of development, cells begin to assume specific functions. Gene regulation ensures that the affected genes are expressed at the appropriate times. Within the gene regulation factors are transcription factors, which are proteins that bind to DNA near the area where the gene is located, helping or inhibiting the transcription machinery. Other forms of regulation include epigenetic processes such as methylation, acetylation, phosphorylation, interference RNAs, among others. This entire regulatory network works together controlling the appropriate rates and times when genes are transcribed into mRNA.

41) a particular triplet of bases in the template strand of dna is 5' agt 3'. the corresponding codon for the mrna transcribed i
KiRa [710]

A particular triplet of bases in the template strand of DNA is 5' agt 3'. the corresponding codon for the mRNA transcribed is<u> 3' UCA 5'</u>

<u></u>

It serves as a link between DNA's genetic code and proteins' amino acid sequences.

The codons in the messenger RNA (mRNA) are complementary to the nucleotide sequence on the DNA template strand.

Then it controls the synthesis of amino acids with the aid of tRNA and ribosomes.

Its name, messenger RNA, refers to the fact that it carries genetic information. The single strands of adenine, cytosine, guanine, and uracil that make up the mRNA molecule are held together by a sugar phosphate backbone.

Two codons: His, Lys, Phe, Tyr, Asn, Asp, Cys, Gln, Glu, Codons Ile, STOP, and three ("nonsense"). Ala, Gly, Pro, Thr, and Val are the four codons. None of the five codons.

Assignment Summary For this assignment, you will model the structures of the cell and describe their functions. You will do this
iren [92.7K]

The model of the structures of the cell and and their functions is given in the image attached.

<h3>What are the cell structure and their functions?</h3>

Some explanation on structure of cells is given below:

The nucleus:

This is known to be the  key or major organelle that tends to sustain or hold the genetic information that is needed  for reproduction and cell growth as well as development.

Note that  all cell is known to be made up of one nucleus and also a kind of membrane-bound organelles that can be seen in the cytoplasm.

Mitochondria:

This is known to be a double membrane-bound organelle that is known to function by acting as the site for the energy transactions and it is made for the survival of all cell.

Therefore, The model of the structures of the cell and and their functions is given in the image attached.
