Q:

What is the nitrogenous base found in DNA but not in RNA?

A:

Quick Answer

Thymine is a nitrogenous base that is found in DNA molecules but not in RNA molecules, according to Vision Learning. Instead of thymine, RNA molecules utilize uracil.

Full Answer

DNA and RNA are both comprised of nucleotides that bind to a sugar backbone. The DNA nucleotide bases include adenine, cytosine, guanine and thymine. The RNA nucleotide bases include adenine, uracil, guanine and cytostine. Another difference between the two compounds is their structure. DNA molecules are double-stranded and their nucleotides are bound together by hydrogen bonds. DNA molecules also utilize deoxyribose as their sugar backbone. RNA molecules are single-stranded and utilize ribose as their sugar backbone, according to Vision Learning.

    Why is DNA called the blueprint of life?

    A:

    Just as blueprints direct the building of a house, DNA molecules contain the genetic instructions used in the development and functioning of a living organism. The DNA of eukaryotic organisms such as plants and animals is organized into linear chromosomes and stored within the nucleus of every cell.

  • Q:

    What makes up the rungs of the DNA molecule?

    A:

    As shown on the NIH Genetics Home Reference site, when DNA molecules are represented as ladders, the rungs represent the base pairs of the DNA. The bases in DNA are often represented as G, A, T and C, which stand for guanine, adenine, thymine and cytosine. When two strands of DNA form a double-strand helix, the bases pair up in the middle of the molecule.

  • Q:

    How is RNA different from DNA?

    A:

    RNA, or ribonucleic acid, is responsible for the transfer of genetic information to cell components called ribosomes. DNA, or deoxyribonucleic acid, is responsible for the transfer and duplication of long-term genetic information during cell reproduction. They are both essential to the process of creating new organisms and the biological functions of organisms.

  • Q:

    How does DNA differ from RNA?

    A:

    DNA is a stable, double helix that functions in long-term storage of genetic material, while RNA is a reactive, single helix that transfers information. There are also slight differences in base pairs between DNA and RNA.
