Please answer and explain
n. These cells are immortal human cancerous cells that have h RNAses, enzymes A student grows Hela cells in the lab to study replicatio been grown in culture for decades. In labs, it is very easy to contaminate solutions and media wit that degrade RNA. Unfortunately, the student's cultures became contaminated. Which of the following processes involved in replication would you expect to be directly affected by this contamination? Explain your answer. 3. a. Separation of the DNA at ARS sequences b. Unwinding of the DNA at the replication fork c. Activity of DNA primase d. Elongation of DNA strands by DNA polymerase Replication of the telomers (telomerase is active in these cells) e.Explanation / Answer
It directly affects the C. Activity of DNA primase, E. Replication of the telomeres.
C. Activity of DNA primase- DNA primase used to synthesis the RNA primers to start the replication. This short RNA sequence complementary to single strand piece of DNA which act as a template. This RNA primer are degraded by contaminanted RNAse.
E. E. Replication of the telomeres. Telomerase is a reverse transcriptase which carries a own RNA template in the enzyme. This RNA template is degrade by RNAse.
