An RNA molecule has the following percentages of bases: A= 23%, U=42%, C=21 %, and G=14%. Is this RNA single stranded or double stranded, how can you tell? What would be the percentages of bases in the template strand of the DNA that contains the gene for this RNA?
Suppose that a mutation occurs in an intron of a gene encoding a protein. What will the most likely effect of the mutation be on the amino acid sequence of that protein?
