process of DNA sysnthesis
replication
process of RNA synthesis
transcription
process of protein synthesis
translation
universal flow of genetics
One direction- DNA-RNA- Protein
where does translation ( protein synthesis) occur inside a prokaroyte cell? eukryote?
out the nucleus for both
where does transcription (RNA synthesis) occur inside a prokaroyte and eukaroyte cell?
in the eukarote cell it is inside the nucleus, prokaryote has no nucleus
how is DNA copied
DNA polymerase
What initiates DNA polymerase
RNA primer
adds nucleotides to the growing DNA strand, 5’ to 3’ end
DNA polymerase
relaxing supercoiling ahead of the replication fork
DNA gyrase
Makes covalent bonds to join DNA strands, Okazaki fragments, and new segments in excsion repair
DNA ligase
Where does DNA replication take place in bacteria and in eukaryotic cells?
Inside the nucleus
strands of the DNA double helix used to make RNA
Template strand
strand of DNA complementary to the template strand
coding strand
binds DNA at the promoter
RNA polymerase
