No, Chromosomes aren't found in DNA, they are thread-like structures located "inside the nucleus" of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).The structure of chromosomes keeps DNA tightly wrapped around spool-like proteins called histones. Humans have 23 pairs of chromosomes, ... Read More

No, there is gravity on the moon. The value of gravity on the moon is one-sixth of the gravity on earth. We can find its value from the formula $g = \frac{Gm}{r^2}$.

Solution :Negative integers cannot be prime. Prime numbers are those numbers that are divisible by themselves and 1. No other number or numbers can divide them. These numbers have only two factors which include 1 as well.Eg: 2, 3, 5, 7, 11, 13, 17....and so on.
