What is the definition of a mutation? - Correct Answer heritable change in genetic material In what ways are mutations important in genetics? - Correct Answer a. the source of all genetic variation b. source of many diseases and disorders c. useful for probing fundamental biological processes What is the difference between a somatic mutation and a germ-line mutation? What cells are affected and how are they inherited? - Correct Answer somatic: from cell to cell. no gametic involvem...

When can mutations occur? - Correct Answer -changes in DNA structure or errors in DNA during replicate -change is inherited importance of mutations - Correct Answer -source of all genetic variation, which further provides the raw material for evolution -source of many disease and disorders -useful for probing fundamental biological processes Somatic mutation - Correct Answer -Arise in somatic cells (most of our cells) -Do not produce gametes -Daughter cells (after mitosis) will...

What are mutations? - Correct Answer changes in the genetic material in our cell What is a point mutation? - Correct Answer when an incorrect nucleotide is put into a DNA molecule during replication What can the change of a single nucleotide in a DNA template strand lead to? - Correct Answer the production of an abnormal protein What are the two general categories that point mutations within a gene can be divided into? - Correct Answer -nucleotide pair substitution -one or more...
