How DNA is packed inside of a chromosome?

Question

I need explanation and the source as well

thanks..

10 points for good answer

Answer 1

the chromosome looks the way is does because it is dna coiled around histone proteins among other things. it is not inside, it is the chromosome.

Answer 2

DNA stands for Deoxyribonucleic acid. This is a coating and an arrangement of proteins and sugars which have 5 carbon atoms attached to them. Most of them are Pentose, Ribose and some others. They form a shape called a helix and two helicies join together to form a DNA strand. The two strands are connected by protein bases which are: Adenine, Guanine, Cytosine and Uracil. Only complementary bases join to each other. This DNA is present in the Chromatids of the chromosomes, Chromatids are attached to the centromere of the chromosome which holds the chromotids together. Its these Chromatids you find something called a locus. This is the position of a specific gene. For example, eye colour, hair colour etc.

Answer 3

Like people have said, DNA is part of a chromosome, not inside of one.  The single long thin molecule of DNA that makes up the "information" part of each chromosome is spun into a "helix."  This helix is like a thread, which in turn is wrapped around protein molecules called histones.  These histones stack into a series of rows (and then bigger coils) that give chromosomes their shape.

Answer 5

A chromosome is made of DNA wrapped around proteins called Histomes.

It's not inside...
