An important difference between mRNA and DNA is
The main chemical difference between DNA and RNA is the sugar that is present within the molecule. As the names would suggest, ribose is the sugar present in all RNA molecules while deoxyribose is the sugar present in DNA molecules. Differences in Chemical Make-Up. The main chemical difference between DNA and RNA is the sugar that is present within the molecule. As the names would suggest, ribose is the sugar present in all RNA molecules while deoxyribose is the sugar present in DNA molecules. 1 DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. 2  The only difference between ribose and deoxyribose is that ribose has one more-OH group than deoxyribose, which has-H attached to the second (2') carbon in the ring. Another major chemical difference between DNA and RNA are in the nitrogen bases that are utilized. In DNA, adenine (A), cytosine (C), guanine (G) and thymine (T) are present, but in RNA, the thymine base is replaced by uracil (U). RNA is of three types namely; mRNA, rRNA, and tRNA. mRNA is formed as a complementary strand to one of the two strands of the DNA. So it carries the same information as DNA in that particular part except that in place of thymine, uracil is present. One difference between DNA and RNA is the sugar. Whereas the sugar in DNA is deoxyribose, the sugar in RNA is ribose. Now, I won't dwell on the exact chemical difference between the two sugars, but ribose has one extra hydroxyl group compared to deoxyribose. Uracil Vs. Another major chemical difference between DNA and RNA are in the nitrogen bases that are utilized. In DNA, adenine (A), cytosine (C), guanine (G) and thymine (T) are present, but in RNA, the thymine base is replaced by uracil (U). Thymine. Another major chemical difference between DNA and RNA are in the nitrogen bases that are utilized. In DNA, adenine (A), cytosine (C), guanine (G) and thymine (T) are present, but in RNA, the thymine base is replaced by uracil (U). DNA vs mRNA. Nucleic acids are large macromolecules found in all known forms of life. There are two types of nucleotides namely; DNA and RNA. mRNA is classified under RNA. In both DNA and mRNA, genetic information is encoded in the sequence of nucleotides, which are arranged into codons. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded. mRNA is short-lived while DNA has a long lifespan.
