valentina_108 [34]
Well,

DNA stands for deoxyribonucleic acid.  RNA stands for ribonucleic acid.  Whereas DNA contains deoxyribose, RNA contains ribose.  Unlike DNA, which holds together through hydrogen bonds, RNA does not employ hydrogen bonding.  DNA has the following nucleotide bases: adenine, cytosine, thymine, and guanine.  Three of RNA's nucleotide bases are the same: adenine, cytosine, and guanine.  In RNA, thymine is replaced with uracil.  Finally, DNA only exists in the nucleus as nuclear DNA or in mitochondria as mitochondrial DNA.  RNA travels back and forth from the nucleus to the ribosomes as a part of protein synthesis.  There are two types of RNA: Messenger RNA (mRNA) and Transcription RNA (tRNA).<span />
