What contains bits of genetic matter that are passed on?

Bits of genetic matter that are passed on are contained in DNA (deoxyribonucleic acid), which is found in the cells of living organisms. DNA consists of sequences of nucleotides that encode the genetic information necessary for growth, development, and reproduction. During reproduction, genetic material is transmitted from parents to offspring, ensuring the continuity of genetic traits. Additionally, RNA (ribonucleic acid) plays a role in translating this genetic information into proteins.
