The function of reverse transcriptase is toa. copy RNA into DNA.b. copy DNA into RNA.c. translate RNA into protein.d. translate DNA into protein.

You are working in the lab and have measured the size of mRNA that has been transcribed from a particular gene in your cell population. The length of the gene in the cells you are working, measured from the start to the stop sequence is 9000 nucleotides. When you measure the RNA, however, the size is only 3000 nucleotides. What do you think happened? O a. Three DNA base pairs code for one RNA nucleotide. b. mRNA does not contain exons. c. There must have been a deletion mutation in the DNA in these cells. Od. The poly-A tail is present in the DNA but not on the mRNA. Oe. RNA splicing occurred, so introns are removed in the mRNA.

RNA transcripts are formed in the   A. 3' to 5' direction by the RNA polymerase reading the DNA template in the 3' to 5' direction   B. 5' to 3' direction by the RNA polymerase reading the DNA template in the 5' to 3' direction   C. 5' to 3' direction by the RNA polymerase reading the DNA template in the 3' to 5' direction   D. 3' to 5' direction by the RNA polymerase reading the DNA template in the 5' to 3' direction

How is the "language" of a molecule made of nucleotides converted into a molecule made of amino acids? O a. Using the process of meiosis, according to the semi-conservative synthesis model O b. Using the process of replication, according to complementary base pairing O c. Using the process of transcription, according to complementary base pairing d. Using the process of translation, according to the genetic code

Answer the following questions about CRISPR below: A.What is a PAM sequence? B.How does the Cas-9/RNA sequence target a piece of DNA for destruction? C.How is the DNA repaired after being cut by CRISPR/Cas-9?

Transposition is a process in which a discrete DNA entity can move between DNA sites that lack homology using a self-encoded protein called a: a. kinase b. transposase c. mobilase d. recombinase
