Bio DNA Nucleotide, Deoxyribose Sugar, Phosphate, Nitrogenous Base, Base pairing, Double helix, chromosome, DNA replication, DNA polymerase

Nucleotide

monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base

Base pairing

principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine

Deoxyribose Sugar

sugar used in DNA to make up the "backbone"

DNA replication

the process of making a copy of DNA

Nitrogenous Base

An organic base that contains nitrogen, such as a purine or pyrimidine; a subunit of a nucleotide in DNA and RNA

Genes

DNA segments that serve as the key functional units in hereditary transmission.

DNA polymerase

Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule

Proteins

Made up of long chains of amino acid residues used for building muscle and energy

Phosphate

PO4 3-

Double helix

Shape of DNA

chromosome

a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
