Please give me the answer to the A-level Biology Question What is the difference between DNA and mRNA?
A-level Biology Help >>>>> What is the distinction of DNA and MRNA? DNA as well as mRNA both are nucleic acid and consist of phosphates, sugars, and the base. However, they're very different. For starters, by looking at DNA molecules, you can see that they are double stranded while MRNA is single stranded. It is a ribose-containing sugar DNA also has Deoxyribose sugar. A great way to remember it is that R = RNA, which stands for Ribose. D = DNA is Deoxyribose. DNA contains four bases that make up the sequence of DNA: thymine the adenine, the guanine and the Cytosine. RNA however , swaps Thymine to make a base known as Uracil. Because of their various structures, they perform different roles!
