    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
