At the beginning of this century there was a general announcement regarding the sequencing of the human genome and the genome of many other multicellular eukaryotes. There was surprise expressed by many that the number of protein-coding sequences was much smaller than they had expected. Which of the following could account for most of the rest?

Select one:
a. non-protein-coding DNA that is transcribed into several kinds of small RNAs without biological function
b. DNA that is translated directly without being transcribed
c. non-protein-coding DNA that is transcribed into several kinds of small RNAs with biological function
d. "junk" DNA that serves no possible purpose
e. rRNA and tRNA coding sequences

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
