DNA Nucleotide
|
One of four kinds of chemical units found in DNA as an informational sequence in groups of three.
|
|
|
RNA
|
single-stranded nucleic acid that contains the sugar ribose.
|
|
|
RNA Nucleotide
|
any of a group of molecules that, when linked together, form the building blocks of DNA or RNA: composed of a phosphate group, the bases adenine, cytosine, guanine, and thymine, and a pentose sugar, in RNA the thymine base being replaced by uracil.

DNA Replication
|
the process of producing two identical copies from one original DNA molecule.

process in which part of the nucleotide sequence of DNA is copied into a complementary sequence in RNA.

|
mRNA
|
RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell.
|
|
|
tRNA

|
|
Translation
|
decoding of a mRNA message into a polypeptide chain
|

|
|
Protein Synthesis
|
the process by which biological cells generate new proteins
