2 Suppose a mutation occurs in a cell such that normal Okazaki fragments were strand. The gene for which enzyme would you predict was altered by this mutation? created duning DNA replication but were not linked together into a continuous A. DNA polymerase B. DNA helicase C. RNA primase D. DNA ligase 3. In spite of a 20 times larger, human genome is also replicated in approximately same amount of time as a bacterial genome because A. Eukaryotic DNA is simpler to replicate than prokaryotic DNA B. Human DNA polymerases work much faster than those of prokaryotes C. The nucleosomes of eukaryotic DNA allow for faster DNA replication D. Human DNA contains more origins of replication than prokaryotic DNA 4. DNA replication is said to be semiconservative because A both RNA and DNA synthesis are involved in the process B. part of the telomere is lost during each round of replication C a new double helix contains one old and one new strand D. each new strand is complementary, not identical, to its template. 5. What happens after the DNA polymerase laying down a new DNA strand meets up with the RNA primer of a preceding Okazaki fragment? A. The other strand is then replicated in the 3 to 5 direction B. The DNA polymerase reverses direction and performs error checking C. DNA ligase couples the two fragments together D. The RNA primer is removed and is replaced by DNAExplanation / Answer
40. DNA replication is called semiconservative because :- c) a new double helix contains one old and one new strand
it is semi-conservative because in replication each original strand is paired with a new strand leaving each of the new DNA strands with one original and one new strand.
