Understand that the question is asking for the name of DNA segments that carry instructions to produce functional products like proteins or functional RNA.
Recall that in genetics, a 'gene' is defined as a segment of DNA that contains the necessary information to produce a functional product, typically a protein or RNA molecule.
Recognize that 'centromeres' are regions of chromosomes important for chromosome movement during cell division, not for encoding products.
Know that 'chromatids' refer to duplicated copies of a chromosome, not specific DNA segments encoding products.
Identify that 'ribosomes' are cellular structures where proteins are synthesized, but they are not segments of DNA.
