Cytosine

Hydrogen Bond AT

Two bonds

Hydrogen Bond GC

3 bonds

Phosphodiester Bond

In DNA Backbone between carboxyl groups

Helicase

Unwinds dna strands

RNA Primase

Lays down RNA Primers for fir ligase to then put together

DNA polymerase 1

replaces rna primers on lagging strand

DNA Polymerase 3

traditional DNA Replication

noncoding regions

regulation

telomeres

protect chromosomes from fusion, aglet for chromosomes

Tandem repeats

defines the direction of transcription, allows for RNA Primers to bind, which then allows RNA Polymerase to bind
