Answer:
B. The available donors and acceptors will induce gene expression of their redox enzymes, thereby allowing their use
Explanation:
Electron transport chain is the important stage of cellular respiration where the electron is donated by certain redox molecules.
The ETC takes place in both the aerobic and anaerobic type of respiration wherein the aerobic respiration, oxygen is used as the electron acceptor whereas in the anaerobic respiration some other molecules like sulfate and nitrate are used.
In anaerobic respiration, the type of electron donors and the donor-acceptor molecules determine the fate of the chain as these molecules act as an inducer of the genes of redox enzymes and the genes for the enzymes are expressed.
Thus, Option-B is correct.
Answer:
The correct answer is - nitrogenous bases in mRNA, a sequence of amino acids.
Explanation:
The translation is one of the two-stage events in protein synthesis. Protein synthesis is the process in which protein or polypeptide chains are synthesized by the DNA.
The translation process is similar to a smartphone app converts spoken English into Spanish as it involves the translation of the sequence of nitrogenous bases in mRNA molecules to the polypeptide or sequence of the amino acids.
Thus, the correct answer is -nitrogenous bases in mRNA, a sequence of amino acids.
The scrotum is a sac of skin that hangs from the body at the front of the pelvis, between the legs. It sits next to the upper thighs, just below the penis. The scrotum contains the testicles
