Homework Answers
During the S phase (synthesis phase) of interphase, DNA replication occurs.
Interphase has the following phases-
- Gap 1 or G1
- Synthesis os S
- Gap 2 or G2
- Mitosis or M
Amomg these, DNA replication occurs in the S phase.

Question 9 1 pts Why does cellular aging (or senescence) occur in eukaryotic organisms? O DNA in eukaryotes is linear, and the ends of the DNA shorten each time replication occurs Telomeres extend the length of the DNA until it becomes too unwieldy to replicate well Extracellular signals tell the cells to stop dividing The nucleotides in the DNA eventually degrade and don't adhere well to each other anymore Question 10 1 pts What evidence do we have against the...

Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...

3. Specifically describe what would occur in DNA replication if the following components were missing, be thoughtful and do not simply state that DNA replication would not occur. Differentiate between prokaryotic and eukaryotic replication when appropriate. DNA ligase- DNA polymerase- Primer- Primase- Topoisomerase- Helicase- SSBP- Sliding clamp/PCNA- Telomerase-
