Why is DNA replication a semi-conservative process?
it results in a a completely new strand of DNA and a strand made of only the original strand
it results in two stands of DNA each composed of one new and one original strand

build a new strand of DNA
break hydrogen bonds between paired nitrogen bases
add a primer for replication to begin
seal gaps in lagging strand
What is the function of the enzyme DNA polymerase in DNA replication?
build a new strand of DNA
break hydrogen bonds between paired nitrogen bases
add a primer for replication to begin
seal gaps in lagging strand
What is the function of the enzyme primase in DNA replication?
build a new strand of DNA
break hydrogen bonds between paired nitrogen bases
add a primer for replication to begin
seal gaps in lagging strand
What is the function of the enzyme ligase in DNA replication?
build a new strand of DNA
break hydrogen bonds between paired nitrogen bases
add a primer for replication to begin
seal gaps in lagging strand
