Answer:
Change in chromatin structure-------Acetylation of histones facilitates transcription
Activity of transcription apparatus------Transcriptional activators increase promoter activity by interacting with the RNAPII holoenzyme
RNA processing---------Alternative splicing produces different transcripts from the same gene.
RNA interference-------A siRNA and the transcript it targets is transcribed from the same gene.
Initiation of translation-------Limited availability of initiation factors prevents translation of mRNA.
You need to be way more specific
The answer is B) stop condons.
Stop codons, UGA, UAA, and UAG, are nucleotide triplets that signal to stop the translation of an mRNA sequence into proteins.
Answer:
B. Proteins
Explanation:
Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).
Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.
Answer:
B. Fertilizer can affect the growth of bean plants.
Explanation:
due to the observation. They observed that these plants, on average, were taller than another population of the same kind of bean plants that were not treated with fertilizer
