How does mRNA differ from DNA?

a. mRNA contains ribose sugars; DNA contains deoxyribose sugars.

b. mRNA contains the base uracil; DNA contains the base thymine.

c. mRNA is single-stranded; DNA is double-stranded.

d. All of the above are correct.

D. all of the above are correct

All of the above are correct.

DNA or deoxyribonucleic acid is the basic genetic material of major life forms except the plant viruses, bacteriophage, and a few other viruses in which either the DNA is absent or any variation of the double-stranded DNA is present.

DNA is composed of three different types of compounds: Sugar molecule: The molecule present in DNA is a pentose sugar, deoxyribose.

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
