Genetics & Cellular Function
What You’ll Learn
DNA and RNA are both nucleic acids that play crucial roles in cellular function and genetic information storage and transfer. DNA has a double-helix structure composed of two strands of nucleotides, with adenine pairing with thymine and guanine pairing with cytosine. DNA stores and transmits genetic information, providing the instructions for cellular processes and organism development. RNA is a single-stranded nucleic acid that comes in various forms, such as messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), and is involved in protein synthesis, gene regulation, and other cellular functions.
