What is the difference between chromosmes, chromatin, chromatid and DNA?

wats the diff? i always hear chromosmes and DNA and chromatin used in the same context, but i tot they were different, where chromsomes are wound up chromatin, which is wound up DNA. and chromatids are identical pairs of chromosomes. am i right?



also, waht phase does each on appear?What is the difference between chromosmes, chromatin, chromatid and DNA?
Obviously, since they are different scientific terms, they actually mean somewhat different things. But they are all related.



DNA is deoxyribonucleic acid, a specific chemical compound.



Chromatin is DNA wound around specific proteins, known as histones.



A chromosome is a gigantic piece of chromatin that contains specific genes as well as a number of other structural elements, like a kinetochore and telomeres, and which is inherited as a distinct structural entity.



Chromatids refer to the two identical copies of a chromosome that are made during cell division, as I recall.



So I guess you are mostly right.



DNA and chromatin are effectively invisible. Again, as I recall, chromosomes/chromatids become visible at metaphase and disappear again at telophase. But you should check this in your textbook.What is the difference between chromosmes, chromatin, chromatid and DNA?
MY bad brain is right only wrong in one point, chromosome refers to the two identical copies of chomatides, and not the other way around (a chromosome is made up of 2 chromatids)

I believe that chromatin is DNA wrapped around histone proteins. and chromosomes are condensed chromatin.
