Question
Introns in eukaryotic protein-coding genes may be quite large, but almost none are smaller than about 65 bp. What is the reason for this minimum intron size?
Step 1
Introns are non-coding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is translated into a protein. Show more…

What are some reasons why, in multicellular eukaryotes, genome size is not necessarily related to the number of protein-coding genes or organismal complexity?
Most protein-coding genes are present in just one copy per genome. Explain why eukaryotic genomes typically contain dozens of copies of histone genes.
RNA Genomes The RNA viruses have relatively small genomes. For example, the single-stranded RNAs of retroviruses have about 10,000 nucleotides, and the Q $\beta$ RNA is only 4,220 nucleotides long. Given the properties of reverse transcriptase and RNA replicase described in this chapter, can you suggest a reason for the small size of these viral genomes?
