similarities between dna and rna
Three of the nitrogenous bases are the same for both RNA and DNA: guanine, adenine, and cytosine. Thymine, the fourth base pair found in DNA, is replaced by uracil in RNA. DNA has deoxyribose sugar while RNA has ribose sugar. The deoxyribose sugar has one less oxygen atom than the ribose sugar.he following distinguishing characteristics can be used to differentiate between DNA and RNA: Pentose sugar-the deoxyribose of DNA has one less oxygen than the ribose of R â¦ NA Nitrogenous bases-DNA contain adenine, thymine, cytosine, guanine; RNA contains adenine, uracil, cytosine, and guanine.
A single DNA nucleotide is made up of a base, a phosphate and a deoxyrib â¦ ose sugar. In RNA, the sugar is a RIBOSE sugar, not a deoxyribose. 3. A DNA nucleotide can have 4 different bases (Guanine, Cytosine, Thymine or Adenine) but an RNA nucleotide will have Guanine, Cytosine, Adenine and URACIL instead of Thymine.4. DNA is only found within the nucleus of the cell.RNA can be found in the cytoplasm of the cell as well as in the nucleus.iruses, which are generally not considered to be living, contain one or the other. Here are some major â¦ differences between RNA and DNA: With the exception of a few viruses, RNA is a single-stranded molecule while DNA is double-stranded. The two DNA chains are connected by hydrogen bonds between nitrogenous bases.
