PPT-ANSWER KEY– LO 3.1 Synthesis of a new DNA strand usually begins with?

A thymine dimer DNA Primer DNA Ligase RNA Primer Describe the process of DNA replication and how sexual reproduction doesnt produce identical offspring from the parent Explain why changes occur in the DNA. Understanding DNA replication – and the resulting transmission of genetic information from cell to cell, and generation to generation – lays the groundwork for understanding the principles of heredity. GO TO . BIOINTERACTIVE WEBSITE. DNA replication questions. Why is DNA replication so important?. In what part of the cell cycle does DNA replication occur?. What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?. genotype to phenotype. Look deep into nature, and then you will understand everything better.. Albert Einstein. . one-gene, one-enzyme hypothesis. Many enzymes are composed of more than one polypeptide chain, or subunit (that is, they have a quaternary structure). In this case, each polypeptide chain is specified by its own separate gene. Thus, it is more correct to speak of a one-gene, one-polypeptide relationship: The function of a gene is to control the production of a single, specific polypeptide..
