Asection of dna encodes a gene for an enzyme involved in cellular metabolism. if a mutation event occurs that results in the deletion of one base near the beginning of this sequence, which of the following is the most likely outcome? a. the loss of one base may or may not seriously affect the protein synthesized, depending on which base is lost. b. the protein synthesized may contain only one erroneous amino acid since the loss of one base will cause one codon to be misread during transcription. c. the protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence. d. the loss of one base will not seriously affect the protein synthesized from the dna sequence.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
