In sweet peas, genes C and P are necessary for colored flowers. In the absence of either (__ pp or
cc __), or both (cc pp), the flowers are white. Give the probable genotype of a plant with colored flowers and a plant with white flowers that produced 38 plants with colored flowers and 42 plants with white flowers. What will be an ideal response?
The mismatch repair system recognizes mismatched base pairs, removes a portion of the DNA strand containing the error, and then resynthesizes the missing DNA using the correct sequence as a template. But what if the mismatch repair system instead removed a piece of the DNA strand that contained the correct sequence? What would replication of this improperly repaired sequence produce?
A. two DNA molecules bearing the same mutation B. two DNA molecules with different mutations C. two DNA molecules that are missing one nucleotide pair D. two DNA molecules with a gap where the correct sequence was excised E. one DNA molecule with a mutation and one DNA molecule with a mismatch
