Discuss Concepts During replication, an error uncorrected by proofreading or mismatch repair produces a DNA molecule with a base mismatch at the indicated position: The mismatch results in a mutation. This DNA molecule is received by one of the two daughter cells produced by mitosis. In the next round of replication and division, the mutation appears in only one of the two daughter cells. Develop a hypothesis to explain this observation.

I. What is the correct order of enzyme action during DNA replication? Number the steps from 1 to 7. HINT: Refer to the slide show and video lecture on this topic to help you solve this one: Synthesis of RNA primers (priming) Ligation II. A double-stranded DNA molecule with the sequence shown below can produce a polypeptide that is four amino acids long. Identify which DNA strands are the coding and the transcribed template strands by circling C or T to the left of the table below, respectively. Use an arrow to indicate the direction of transcription. In the table, show the mRNA sequences and amino acids in this peptide. In spaces to the left and right of the table, label all 5' and 3' ends of all relevant nucleic acid strands. READ CAREFULLY: The table gives you the possibility of filling in answers that show transcription from either strand or in either direction. You are only required to fill in the information relevant to ONE PEPTIDE (no others). Refer to the genetic code on the…

Some Processes Involved in DNA Replication 1. The replication origin is identified. 2. DNA primase builds RNA primer. 3. Okazaki fragments are spliced by DNA ligase. 4. Helicases bind and uncoil the DNA double helix. 5. RNA primer is the starting point for DNA polymerase. 6. DNA replication ends at the telomere where DNA codes for termination. 7. DNA polymerase adds complementary nucleotides in the 5' to 3' direction in short segments called Okazaki fragments. The sequence in which the events numbered above occur during DNA replication of the lagging strand is , and
