In ribosomes with DNA polymerase
4.
What are the firsts couple of steps of DNA replication?
a)
DNA is unwinded > Helicase seperates strands > DNA primase comes in to create a primer
b)
DNA primase comes in to create a primer > DNA is unwinded > Helicase seperates strand
c)
DNA is unwinded > DNA primase comes in to create a primer > Helicase seperates strand
d)
Helicase seperates strand > DNA is unwinded > DNA primase comes in to create a primer
5.
What are the last couple of steps of DNA replication?
a)
DNA ligase handles Okazaki fragments > DNA polymerase creates base pairs > single strand binding proteins make sure two strands dont come back 2gether
b)
DNA polymerase creates base pairs > DNA ligase handles Okazaki fragments > single strand binding proteins make sure two strands dont come back 2gether
c)
single strand binding proteins make sure two strands dont come back 2gether > DNA polymerase creates base pairs > DNA ligase handles Okazaki fragments >
d)
DNA polymerase creates base pairs > single strand binding proteins make sure two strands dont come back 2gether > DNA ligase handles Okazaki fragments
