Why is an RNA primer necessary for DNA replication a. The RNA primer is necessary for the activity of DNA ligase b. The RNA primer creates the 3’ end for DNA polymerase to add nucleotides  c. DNA polymerase can only add nucleotides to RNA  d. RNA primer is not necessary for DNA replication

Eukaryotes such as humans have linear chromosomes. In order to signal the end of DNA replication, there is a large repetitive sequence of DNA called a telomere. The telomere region of the DNA signals a process called a. detachment b. termination c. elongation d. transcription

DNA that has been  labeled with 15N is used as the template for replication. Replication is carried using 14N labeled dNTP's. After 3  rounds of replication, what percent of DNA molecules have one strand containing 15N and one strand containing 14N?   A. 50%   B. 75%   C. 25%   D. 100%
