The genetic code carried by macromolecules is called:
A. DNA
Explanation:
DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known organisms and many viruses. It consists of two long chains of nucleotides twisted into a double helix and contains the genetic code for an organism.
B. Chromosomes are long DNA molecules with part or all of the genetic material of an organism. Chromosomes are structures within cells that contain DNA.
C. Nucleotides are the basic building blocks of DNA and RNA, consisting of a phosphate group, a sugar molecule, and a nitrogenous base. They form the structure of DNA and RNA but are not themselves the genetic code.
D. RNA (Ribonucleic Acid) is another type of nucleic acid that plays a role in translating the genetic code from DNA into proteins. While RNA carries genetic information in some viruses and is involved in protein synthesis, it is not the primary carrier of genetic information in most organisms; that role is filled by DNA.
