Rainbow [258]

False, because chromosomes are architecturally very compact and genetic code for them, they are not responsible for the specific features we witness.

Contrary to appearance, chromosomes are very compressed physically, allowing for the containment of these enormous DNA structures within the cell nucleus. A human's chromosomes. The genetic code refers to the set of guidelines that living cells employ to convert data from genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. The ribosome does translation by linking genetic code amino acids in the order dictated by messenger RNA (mRNA) and employing transfer RNA (tRNA) molecules to transport amino acids.
