Honors HSBio 7 - DNA and Cell Division

DNA

stands for deoxyribonucleic acid, the double stranded genetic molecule that provides the code for our traits

Double Helix

the shape of DNA with two strands twisted around each other, a double twisted staircase

Nucleotide

buiding blocks of nucleic acids

Nitrogen Base

DNA has four, Adenine, Guanine, Cytosine, Thymine. These pair up A with T and C with G.

DNA replication

process where DNA makes a copy of itself

Deoxyribose

sugar found in DNA

Cell Cycle

series of events in which a cell grows, prepares for division and divides to make two daughter cells

Mitosis

cell division in body cells that occurs for growth and repair

Chromosomes

threadlike structure of DNA and protein that contain genetic information

Nucleic Acid

made up of nucleotides, stores and transmits geentic and hereditary information

helicase

enzyme that unwinds DNA

DNA polymerase

enzyme that builds new strands of DNA
