WebThe letter A indicates a _____. A nitrogenous base is indicated by the letter _____. c. You can tell that this is an image of a DNA nucleotide and not an RNA nucleotide because you see a _____. sugar with two, and not three, oxygen atoms. Which of these nitrogenous bases is found in DNA but not in RNA? WebDNA is a double helix; 2 strands, each one has coding areas ( which are 2% and maybe less) and non-coding areas . Within the gene itself there are non-coding sequences which their name is “ introns “. The non-coding area (outside the gene) of DNA strand has different types of sequences ; satellites and repeated sequencing . Is that true for now? •
