Q:

Where is RNA found in the cell?

A:

Quick Answer

Ribonucleic acid, also known as RNA, is found almost exclusively in the cytoplasm of cells, although at times it can created in the nucleus of the cell. RNA is a major biological macromolecule that is required for life.

Full Answer

Along with RNA, DNA and proteins are also required for life. DNA, or deoxyribonucleic acid, is composed of the genetic information of a cell that determines how it behaves, maintains itself and grows. RNA is created as a copy of certain parts of the DNA. The RNA is then used by another component of cells, ribosomes as a set of instructions for what proteins should be made to accomplish a certain task.

  • Q:

    What is antisense RNA technology?

    A:

    Antisense RNA technology is a treatment for genetic disorders or infections that involves turning off the gene causing the disease. This is done by synthesizing a strand of DNA or RNA that binds to the mRNA produced by the gene and deactivates it. Antisense RNA technology has been largely unsuccessful due to its toxicity, problems with delivery methods, instability, manufacturing cost, administration and circulation time.

  • 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.

    What replaces thymine in RNA?

    A:

    Uracil in RNA replaces thymine in DNA, according to ScienceDaily. Both uracil and thymine bond with adenine, the complementary base found in both the RNA and DNA structures.

  • 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.
