At the beginning of this century there was a general announcement regarding the sequencing of the human genome and the genomes of many other multicellular eukaryotes. many people were surprised that the number of protein-coding sequences was much smaller than they had expected. which of the following could account for much of the dna that is not coding for proteins?
select one:
a. non protein coding dna that serves as binding sites for reverse transcriptase.
b. dna that consists of histone coding sequences.
c. non protein coding dna that is transcribed into several kinds of small rnas with biological function.
d. dna that is translated directly without being transcribed.
