Chromosome vs Chromatid vs Chromatin

[Maki]

:S :S :S :S :o_o:

What is the difference between a chromosome, a chromatid, and a chromatin?
I've been searching all over on Google but I think it's got me confused even more :(

Here's what I have written down:
CHROMATIN
> DNA strand as a whole

CHROMATID
> half the DNA strand
> two chromatid = one chromatin

CHROMOSOME
??????
lol

In my textbook it says a chromosome makes up a portion of the cell's DNA but isnt that what a chromatid is??

Help please. Will +rep :) Please tag me, I must know this

Ok... How to write this in English.

A Chromosome is made of DNA. (As the same form as an X)

Chromatin is a bunch of filaments that contains DNA. When they condensed, they become a chromosome.

Chromatid is a molecule of DNA and represents 1 part of a chromosme (Half of the X) So there's 2 chromatids in 1 chromosome.

lol learned this last year :o_o:

my understanding from my teacher is referring to the same material in different forms.

chromatin = uncoiled messy blob of genetic material in nucleus.
chromatid = when the above is coiled
chromosome = a pair of chromatids


katzes beat me to it! :D

(ADN in English is DNA, btw)
