Sometimes, chemical damage to dna can occur just before dna replication begins, not giving the repair system enough time to correct the error before the dna is duplicated. this gives rise to mutation. if the cytosine in the sequence tcat is deaminated and not repaired, which of the following is the point mutation you would observe after this segment has undergone two rounds of dna replication?

1)ttat

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
