Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
That would be a, chemical to mechanical
Answer:
d
Explanation: the genes carry what is needed to change, and the cells change due to what is happening in the genes
Answer:
the making of a polypeptide with a specified order of amino acids using an RNA molecule to provide the sequence information
Explanation:
<u>Translation is the making of polypeptide with a specified order of amino acids using a RNA molecule to provide the sequence information.</u>
In order word, translation is the process of synthesizing protein from mRNA synthesized from DNA template.
<em>During the process of gene expression, the information in the DNA are first transcribed into a mRNA in the nucleus. Thereafter, the mRNA is transported out of the nucleus to the cytoplasm where the genetic codes present in it are translated into their respective amino acids and become linked together through a peptide bond.</em>
Each polypeptide formed has a specific amino acids which correspond to the codons on the mRNA.
