what are the monomers of DNA called
nucleotides
give the 4 DNA bases
adenine thymine guanine cytosine
when nucleotides link to form a DNA strand, explain what happens
the OH on a phosphate bonds to the OH on a sugar producing a molecule of water
what is DNA
deoxyribose nucleic acid is a condensation polymer formed from a sugar, phosphate, base
define nucleotide
sugar phosphate group base
what is the sugar called in a DNA nucleotide
2- deoxyribose
what bonds hold together multiple nucleotides in a polynucleotide strand
(sugar phosphate) phosphodiester bonds
how many hydrogen bonds form between A and T
A = T
how many hydrogen bonds form between G and C

what does the sequence of bases provide information about
sequence of bases provides information about the sequence of a/a in the synthesis of a protein the code used is called a triplet code where 3 bases make an amino acid
what is the triplet code
3 bases code for an amino acid
