The associated figure shows a diagram of blocks of genes on human chromosome 16 and the locations of blocks of similar genes on four chromosomes of the mouse.
The movement of these blocks suggests that ________.
A) during evolutionary time, these sequences have separated and have returned to their original positions
B) DNA sequences within these blocks have become increasingly divergent
C) sequences represented have duplicated at least three times
D) chromosomal translocations have moved blocks of sequences to other chromosomes
E) higher mammals have more convergence of gene sequences related in function

Question

The associated figure shows a diagram of blocks of genes on human chromosome 16 and the locations of blocks of similar genes on four chromosomes of the mouse.
The movement of these blocks suggests that ________.
A) during evolutionary time, these sequences have separated and have returned to their original positions 
B) DNA sequences within these blocks have become increasingly divergent 
C) sequences represented have duplicated at least three times 
D) chromosomal translocations have moved blocks of sequences to other chromosomes 
E) higher mammals have more convergence of gene sequences related in function

Quizplus · Accepted Answer

The movement of blocks of genes on human chromosome 16 to four other chromosomes in mice suggests chromosomal translocations have occurred, leading to the relocation of these gene blocks. This is suggested by the fact that the blocks are found on different chromosomes in mice, indicating that they have been moved from their original position.
