dna replication

where

s-phase

is replication conservative or semi-conservative

semi-conservative

semi-conservative rep

one daughter strand + one parent strand

dna polymerase

synthesis of polynucleotide strand

topoisomerase

decoiling

helicase

unwinding

primase

attaches rna primer for dna strand synthesis

ligase

phosphodiester bond formation

telomerase

replicates dna at end of chromosomes

duplication

prevents mutations

stages

initiation, elongation, termination

initiation

unwinding the DNA double helix with helicase and assembling the replisome to start synthesis

elongation

new DNA strands synthesized by DNA polymerase, adding complementary nucleotides to existing template strands

termination

replication forks meet, synthesis completes, the machinery disassembles, and intertwined daughter DNA molecules are separated

is RNA polymerase involved in transcription

yes

does rna poly require transcription factors

yes- for correct binding to start site

rna poly bases

AUGC

rna poly reads in

3’ to 5’

protein kinase

requires ATP for phosphate
