1. A piece of DNA is labeled so that all of the bases fluoresce red. A student adds a polymerase After the uses green bases and allows the DNA to replicate once more. What are the colors of the newly replicated DNA strands? which uses only blue labeled bases and allows the DNA to replicate twice completion of both cycles, the student adds another polymerase which only a. 2 red/green, 2 all blue, 4 green/blue b. 2 red/green, 6 green/blue c. 2 red/blue, 2 all green, 2 all blue, 2 green/blue d. 2 red/blue, 4 all blue, 2 green/blue 2. Which of the following is FALSE regarding DNA replication? a. DNA replication requires an RNA primer. b. Nucleotide tes are added to the 3' end. c Bacteria require telomerase to complete their DNA strand synthesis. d. Helicase is required prior to DNA synthesis. a. A nucleotide analogue b. An alkylating agent C. A? intercalating agent d. An oxidizing agentExplanation / Answer
1) b) 2 red/green 6 green/blue
RR -B-> RB and RB -B-> RB BB RB BB -G-> RG BG BG BG RG BG BG BG
So 2 RG and 6 BG
R stands for Red color strand
B stands for Blue color strand
G stands for Green color strand
2) C) Bacteria require telomerase to complete their DNA strand synthesis.
Bacteria do not require telomerase as their DNA is circular
3) 2 aminopurine - a) a nucleotide analogue
It is a purine analog of guanine and adenine and also a fluorescent molecular marker.
