Explain how the role of DNA and chromosomes is crucial in coding the instructions for characteristic traits.
DNA and chromosomes are unrelated to trait inheritance.
DNA contains genes, which are segments that code for traits, and chromosomes organize these genes.
Chromosomes are proteins that directly code for traits.
DNA is a type of protein that influences trait expression.

Defend the claim that viable errors during DNA replication can lead to genetic variation.
Errors in replication always result in harmful mutations.
Errors can introduce new alleles, which may be beneficial, neutral, or harmful, contributing to variation.
Replication errors are corrected immediately and do not affect genetic variation.
Errors in replication only occur in somatic cells and do not affect inheritance.
