Question

1. If DNA polymerase III was going to attach a new nucleotide onto the DNA molecule shown to the right, where would it attach it? 2. Why are the ends labeled A and C different? a. The diagram is drawn incorrectly, they should be the same One is o pure onsa pyrimidine. c. One is a purine, one is a pyrimidine d. Double-stranded DNA is antiparallel. e. This is after DNA replication -before DNA replication, they look the same. 3. If 20% of a DNA molecule is made up of adenine bases, what percent would be made up of guanine? d, 80% e. There would not be any guanine. 20% 3090 50% a. b. c. 4. Which of these statements is true about DNA replication in prokaryotes compared to eukaryotes? a. Prokaryotes do not replicate their DNA. b. Both prokaryotes and eukaryotes require telomerase. c. Eukaryotes have multiple origins of replication, while prokaryotes only have one. d. Eukaryotes must replicate their DNA before they synthesize a protein, while prokaryotes can perform both processes simultaneously. e. Eukaryotes use DNA polymerase 3, prokaryotes use RNA polymerase 2

Answer 1

Answer. 1 C because new bases are added to 5' of DNA by the 3' end.

Answer 2. Double stranded DNA is anti parallel.

One strand run in 3' to 5' while other run in 5' to 3'

Answer 3. 30% because adenine is 20% then then percentage of thymine will be 20% in total 40% the rest is 60% so half will be shared by guanine and half with cytosine. So in total 30%.

Answer 4. Eukaryotes must replicate their DNA before they synthesize a protein, while Prokaryotes can perform both process simultaneously
