Question 4 About endonucleases: A Restriction endonucleases always cut double-stranded DNA and are endo- deoxyribonucleases. B Once the DNA sequence is recognized, they cleave the bond between the desoxyri- bose and the nitrogenous base. |C they are proteins that are necessary for the replication of DNA. D they act on single-stranded DNAS, RNAS, and double-stranded DNAS. E they are enzymes whose substrate is a double-stranded sequence of nucleic acids, DNA or RNA, or hybrid DNA-RNA.

Partial Question 6 Which of the following are true about replisome components at the replication fork? There are two DNA helicases at each replication fork: one for the leading strand and one for the lagging strand. There are two sliding processivity clamps at each replication fork: one for the leading strand and one for the lagging strand. Primase synthesizes new primers made of DNA every -500-5000 nt on the lagging strand. The clamp loader complex (y) loads new sliding processivity clamps (B) every ~500-5000 nt on the lagging strand. The two DNA polymerase cores travel together in the same direction even though the two template DNA strands run 5'→3' in the opposite direction (antiparallel).

Given the choices,a. 26b. 23c. 27d. 21how many hydrogen bonds are present in a DNA double helix fragment consisting of the following sequence in one strand: GCTGTGCACT
5'-GCGGTACGTTACGGCTTTACTGACCTGCAGGC-3' A. Convert this to a double strand DNA molecule by writing the complementary sequence. Be sure to correctly label the ends of the double stranded molecule B. Pick one of the two strands and write the sequence of an RNA molecule that could be transcribed from it. Again, you must correctly label the ends of the molecule.
