    Study Notes

    Understanding Nucleic Acids: DNA and RNA

    • The Central Dogma of molecular biology explains the flow of information from DNA to RNA to protein in all organisms.
    • A gene is a specific segment of DNA composed of distinctive sets of nucleotide pairs in a discrete region of a chromosome that encodes a particular protein.
    • Genotype refers to the genetic composition of an individual, while phenotype refers to the observable characteristic of an individual.
    • Nucleic acids, DNA and RNA, are linear polymers of nucleotides that are required for the storage and expression of genetic information.
    • Nucleotides are the basic building blocks of DNA and RNA, consisting of a nitrogenous base, a pentose sugar, and a phosphate molecule.
    • There are two types of nitrogenous bases: purines (adenine and guanine) and pyrimidines (cytosine, thymine, and uracil).
    • The two types of pentose sugars are deoxyribose (in DNA) and ribose (in RNA).
    • Polynucleotide chains are formed by covalently bonding nucleotides via 3'→5' phosphodiester bonds, resulting in a chain with a 5'→3' direction.
    • The double helix structure of DNA is composed of two polynucleotide chains running in opposite directions, with complementary base pairing (A-T and G-C) held together by hydrogen bonds.
    • DNA has a high coding capacity and offers a molecular explanation for mutation and copying.
    • The double strands of DNA can separate into single strands, and complementary strands can reform the double helix under appropriate conditions.
    • RNA is a single strand that has direction from 5'→3' and bases sequence always written from 5'-end to 3'-end, and it plays a role in protein synthesis.
