What is the difference between a chromatid and a chromosome? see section 12.1 ( page 255) . what is the difference between a chromatid and a chromosome? see section 12.1 ( page 255) . chromatids consist of dna, whereas chromosomes consist of proteins. a chromatid always consists of two linear dna molecules, whereas a chromosome always consists of just one linear dna molecule. chromosomes are always replicated, whereas chromatids are not. a chromatid is one half of a replicated chromosome, whereas a chromosome consists of dna wrapped around proteins in a highly organized manner?

Answer 1

I believe that the answer is that a chromatid is one half of a replicated chromosome, whereas chromosome consist of DNA wrapped around proteins in a highly organized manner. A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
