Dna replication

Question 1

where does DNA replication take place?

Answer 1

tales place during the interphase of a cell cycle, must occur before a cell can undergo nuclear division

Question 2

what are the two enzymes involved in DNA replication?

Answer 2

DNA helicase (breaks hydrogen bonds), DNA polymerase (forms phosphodiester bonds)

Question 3

what are the two enzymes involved in DNA replication?

Answer 3

DNA helicase (breaks hydrogen bonds), DNA polymerase (forms phosphodiester bonds)

Question 4

what is the other name for DNA replication?

Answer 4

semi-conservative - this is because each of the new DNA molecules will contain one strand of the original. It ensures genetic continuity between generation of cells.

Question 5

what’s the first step of DNA replication?

Answer 5

DNA helicase breaks the hydrogen bonds between the 2 DNA strands.

Question 6

what happens in the second stage of dna replication?

Answer 6

free/ unbound DNA nucleotides pair up with the complementary exposed bases

Question 7

what is third step of DNA replication?

Answer 7

DNA polymerase (enzyme) join the nuleotides togethere with phosphodiester bonds during a condensation reaction

Question 8

what is third step of DNA replication?

Answer 8

DNA polymerase (enzyme) join the nuleotides togethere with phosphodiester bonds during a condensation reaction

Question 9

how does a two DNA strands with only N-14 strands divide?

Answer 9

1. they replicate using N-15 nucleotides
2. then they replicate using N-14 nucleotides
