Bad White [126]

Answer:

A. transmission genetics

B. population genetics

C. molecular genetics

D. genomics

E. molecular genetics

Explanation:

Transmission genetics can be defined as the study of the mechanisms involved in the inheritance of genetic material by offspring from parents. This discipline started with the discovery of inherited characteristics in pea plants by Mendel (1865).

Population genetics is a subdiscipline of genetics that studies genetic variation within and between populations. Population genetics is an area that explains how allele and genotypic frequencies change across time, thereby this subdiscipline is closely linked to evolutionary biology.

Genomics is a broad area of genetics that studies the function, evolution, structure, function, mapping and comparison of genomes (i.e., the whole genetic material contained in each cell of a given organism). This discipline aims at understanding entire gene pools. Genomics includes different research areas including structural genomics, functional genomics, epigenomics and metagenomics.

Molecular genetics is a sub-discipline of genetics that studies the mechanisms involved in preserving the genetic material (i.e., DNA and RNA), and to understand how the structure and expression of the genetic material influence the observed variation among organisms.

Which biomolecule is the most diverse and has a variety of functions? *
ryzh [129]

Answer: Proteins

Explanation:

Proteins are one of the most plentiful naturally-grown molecules in living systems and possess the most distinctive extent of duties of all macromolecules. The purposes of proteins are highly distinct for 20, unlike chemically different amino acids that develop large chains, plus the amino acids can occur in any method. Proteins may be architectural, regulatory, contractile, or shielding; they may work in transportation, storage, or membranes; or they may be poisons or enzymes. An instance of the function of proteins: proteins can work as enzymes or hormones. Enzymes made by living cells are catalysts in biochemical reactions and are usually proteins.
