Answer:
D. chemical digestion
Explanation:
In chemical digestion, large food molecules are broken down into smaller particles thanks to the action of enzymes present in the digestive juice, undergoing changes in their chemical composition.
Chemical digestion is a process that occurs with the action of enzymes. It starts in the mouth with the action of the enzyme amylase, which is present in saliva and digesting starch. In the stomach, there is the action of gastric juice, consisting of hydrochloric acid and the enzyme pepsin, which acts on protein digestion. In the small intestine, the food undergoes the action of substances produced by the pancreas (alkaline substance containing trypsin and chymotrypsin, enzymes that act on proteins) and by the liver (bile, which contains salts that act on the digestion of fat, is produced by liver but is stored and concentrated in the gallbladder).
The mutations may be a
substitution, deletion, inversion, or addition.
The mutations in insulin may alter its active sites responsible
for receptor binding, or the time taken for the insulin
to be degraded (half-life). Mutation on insulin may cause diseases such as hyperproinsulinemia
or hyperinsulinemia.
Answer:
C) binding to mRNAs and degrading them or blocking their translation
Explanation:
<u>miRNAs:</u>
miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.
They silenced mRNA by the following processes:
(1) Cleavage of the mRNA strand into pieces,
(2) stopping mRNA from translation into proteins by ribosomes.
(3) Shortening of mRNA poly(A) tail and destabilizing it.
