DNA Replication Worksheet
DNA replication results in two DNA molecules, ___________________________________________
A. each with two new strands B. one with two new strands and one with 2 original strands
C. each with two original strands D. each with one new strand and one original strand
DNA replication is said to be semiconservative because:
A. both RNA and DNA synthesis are involved in the process.
B. part of the telomere is lost during each round of replication.
C. a new double helix contains one old and one new strand.
D. each new strand is complementary, not identical, to its template.
In DNA, guanine always forms hydrogen bonds with __________________.
The process of __________________ produces a new copy of an organism’s genetic information, which is passed on to a new cell.
What is the first step in the process of DNA replication? ___________________________________________
Which enzyme is responsible for “unzipping” the DNA double helix? __________________________________________
Which enzyme is responsible for assembling the DNA during replication? ________________________________
Why is DNA replication important to the growth and development of a multi-cellular organism?
