RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.
Answer:
c) Amino acids
Explanation:
Proteins are long-chain molecules made of amino acids. They are linked through a covalent peptide bond. Therefore, the option (c) is the correct answer.
A heterotroph is an organism that relies on complex organic substances for nutrition. <span>A </span>heterotroph<span> is an animal that can't make its own food supply, so they have to eat other things, like plants or other animals, to survive. Hope this answers the question.</span>
<u>Answ</u>er:
False
,Cellular respiration not is the oxygen dependent process through which food molecules are broken down and the energy released used to generate atp.
<u>Explanation</u>:
Glycolysis is the primary phase in the collapse of glucose to abstract energy for cellular metabolism. Almost every living organisms bring out glycolysis as step of their metabolism. The method does not use oxygen and is hence anaerobic. Glycolysis occurs in the cytoplasm of equally prokaryotic and eukaryotic cells. Glucose arrives into the heterotrophic cells in two ways.
1. Over secondary active movement in which the movement occurs against the glucose concentration gradient.
2. Over a cluster of vital proteins called GLUT proteins, also called as glucose movement proteins. These transporters helps in the simplified diffusion of glucose.
