1. The genome of organism A consists of approximately 2.184 ×109 base pairs, and DNA synthesis occurs at a rate of 500 base pairs per second. How many minutes would it take to synthesize the entire genome of organism A, if there were only one origin of replication? 2. It turns out that organism A is actually able to synthesize its entire 2.184 ×109 bp genome in only 35 minutes. How many origins of replication must there be? 3. The...

Which of the following statement about DNA is FALSE? When bacteriophage DNA was shown to be the agent necessary for production of new phages, this was the early experiment demonstrating that DNA is the hereditary material. During DNA replication, two replication forks are formed to complete the synthesis of the entire chromosome in eukaryotes. During bacterial DNA replication process, replication forks move in opposite directions away from the origin of replication The molecular structure of DNA...

Which of the statement is true? If a double-stranded DNA molecule of 125 million base pairs were scaled to the size of a human hair, it would have a diameter of 0.003 inches and be 1 mile long. If this scaled-up DNA molecule were condensed and compacted into a chromosome, into which of the objects below could that chromosome fit? A. a tennis ball B. a bathtub C. a pencil eraser D. a soda (pop) can E. a basketball

Which are true about direct repair of DNA? O The damaged base is excised and a new segment of DNA is synthesized to fill in the gap. Error-prone DNA polymerases are used to insert a nucleotide opposite to the damaged base. O A damaged base is restored to its correct structure without removing it from the DNA. O DNA ligase is needed. O Methylation marks can be used to distinguish the correct strand from the incorrect strand.

One copy of the human genome is 3 billion (3 X 109base pairs). Pretend that instead of 4 bases (AGCT) there are 5, and that the 5th base (called D) pairs with itself. Pretend also that all 5 bases are present at equal frequency in the human genome. Suppose you digested to completion one copy of the human genome with the enzyme Eco RI (recognition sequence 5'-GAATTC). A Given the information above about the 5thbase, what would be the average...
