Answer:
The difference between molecular biology and comparative biochemistry are:
Molecular biology is the branch of biology in which we study about the chemical composition and structure of atoms of macromolecules such as protein and nucleic acid which are the main component of life forming substances, while Comparative biochemistry is a branch of chemistry in which we study the similarities and differences between different biological processes that occurs in different living organisms.
Answer:
Thioredoxin
Explanation:
Ribonucleotides serve as precursors for synthesis of deoxyribonucleotides and the reaction is catalyzed by enzyme ribonucleotide reductase. The reduction of a ribonucleotide into deoxyribonucleotide requires a pair of hydrogen atoms.
These hydrogen atoms are supplied from NADPH via ubiquitous protein thioredoxin. The oxidized form of thioredoxin is reduced back in a reaction catalyzed by thioredoxin reductase.
