which of the following statements accurately describes genetic mutations
Which of the following statements about mutations are true? * Mutations are always passed down to future generations. Mutations decrease the genetic diversity of organisms. Mutations occur only in somatic cells since they are diploid. Mutations are changes in the phosphate backbone of DNA which always have harmful effects. Mutations always cause a frameshift. Mutations can be harmful, neutral, or beneficial to the organism. Mutations are changes in the nucleotide sequence of a DNA molecule. Mutations may cause a change in the protein sequence resulting from the genetic code for that gene.

In the replica plate experiment, it shows that mutations are random. However, certain environmental stresses (such as high temperature, high salt, and low pH) can increase the mutation rate. QUESTIONS: Does increasing the mutation rate increase the probability that a cell will experience an adaptive mutation?
DNA replication is a process that involves copying the DNA molecule. If a single base was miscopied, what would be a possible result of this for the cell in which it happened? Top of Form All the proteins the cell creates from the miscopied strand will do different jobs than the old ones. If the new sequence codes for the same amino acid as the original cell, it will function normally. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded. Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides.
