Question

The parts of a chromosome are labeled. The top, shorter portion is labeled a.
Which is indicated by the letter a?
petit arm
queue arm
centromere
gene

Answer 1

.answer:

petit arm

explanation:

all human chromosomes have 2 arms, the p (short) arm and the q (long) arm. they are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division.

the symbol "p" stands for "petit", small in French, while "q" was chosen merely because it was the next letter in the alphabet.

Answer 2

Answer:

It should be the petit arm.

Explanation:

You have to know about science to figure this out. Here is why, if you look at the image one of the arms is longer than the other. This is the q(long) arm. The smaller one is the P(small) arm. Petit is french meaning small. the part wher they meet in the middle be the centromere. you can remember this because it is in "center".   the lines on it are genes. why? because this is the only answer left ;)    hope this helped
