Cards

Term
nucleotide
Definition
-building blocks of nucleic acid
-3 parts: sugar (pentose)+phosphate+base
Term
DNA
Definition
-sugar: deoxyribose
-base: A (adenine
T (thymine)
C (cytosine)
G (guanine)
Term
DNA Structure
Definition
double helix with 2 sugar phosphate stands with paired bases in middle
-pairing A-T, C-G
found in nucleus and associated with proteins called histones (chromatin and chromosomes)
Term
dna replication
Definition
-occurs during s phase of cell cycle
-enzyme called polymerase binds to origin sight of DNA
-the 2 stands of DNA pull apart
-each strand is copied
-the strands recombine connected at centromere
Term
RNA
Definition
same as DNA except only has a single strand
Term
what sugar does RNA use
Definition
