Q:

What is the site of the production of ribosomes?

A:

In eukaryotes, organisms that have nuclei, ribosomes are produced within the nucleolus of a cell. The nucleolus is located within the cell's nucleus, where most of a cell's genetic information is stored.

Ribosomes are cell organelles that are responsible for making proteins out of amino acids. Organisms need proteins to carry out life functions, such as growth and repair. Therefore, a tremendous number of ribosomes are sometimes required. For example, when mammal cells grow, they hold anywhere from 5 million to 10 million ribosomes. Each time a cell divides, the material inside, including the ribosomes, must be duplicated. The nucleolus, therefore, is often busy manufacturing ribosomes.

    What is a CAAT box?

    A:

    The CAAT box refers to a short consensus sequence of nucleotides in DNA that occur close to (about 80 base pairs away) the transcription start site of a gene in eukaryotes. The transcription start site of a gene is where the RNA polymerase II begins making RNA.

    What are examples of condensation nuclei?

    A:

    Dust, soot and bacteria are examples of condensation nuclei. Water vapor condenses and forms on these small particles, which causes rainfall. Condensation nuclei are commonly called cloud seeds.

  • 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:

    What is the function of tRNA?

    A:

    The function of tRNA is to decode an mRNA sequence into a protein and transfer that protein to the ribosomes where DNA is replicated. The tRNA decides what amino acid is needed according to the codon from the mRNA molecule. Then the tRNA molecule attaches the amino acid to the amino acid chain and returns to the cytoplasm to do it all over again.
