Refer to the table.A gene might affect the length of bristles of a beetle.Using CRISPR technology, biologists have altered the sequence of this gene at three different nucleotides (765, 2901, and 4576) and have measured the length of bristles (in millimeters, with calculated means).In nature, most beetles have A at position 765, G at position 2901, and A at position 4576 (see beetle 1). Changing A to T at position 765 _______ the length of bristles, and changing G to C at position 2901 _______ the length of bristles.
A) increases; increases
B) increases; has no effect on
C) has no effect on; increases
D) has no effect on; decreases
E) decreases; has no effect on
