meiosis- division of a nuclear material of a sex cell (DNA doubles)
DNA replicates itself- a helix (twisted chromosome). Mirror images unzips, enabling nucleotides to bond to the new Free bond space, but only the one that fits. Helix does not completely unzip held together by centromere.
Each cell has 46 chromosomes (23 pairs).
nucleotide- monomer of nucleic acid.
Bases-
A bonds to T
T bonds to A
C bonds to G
G bonds to C
DNA wraps around histome, to form a chromosome.
homologous pair- code for the same trail, not necessarily the same product.
