Protein Synthesis
Protein Synthesis Vocab
Term | Definition |
---|---|
DNA | (deoxyribonucleic acid) the material that contains the information that determines inherited characteristics. |
mRNA | messenger RNA, a single-stranded RNA molecule that encodes the information to make a protein. |
Nucleotide | in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base. |
RNA | (ribonucleic acid), a natural polymer that is present in all living cells and that plays a role in protein synthesis. |
Transcription | the process of forming a nucleic acid by using another molecule as a template; particularly the process of synthesizing RNA by using one strand of a DNA molecule as a template. |
tRNA | Transfer RNA, an RNA molecule that transfers amino acids to the growing end of a polypeptide chain during translation. |
rRNA | ribosomal RNA, an organelle that contains most of the RNA in the cell and that is responsible for ribosome function. |
Translation | the portion of protein synthesis that takes place at ribosomes and that uses codons in mRNA molecules to specify the sequence of amino acids in polypeptide chains. |
Protein | An organic compound that is made of one or more chains of amino acids and that is a principal component of all cells |
Amino Acid | Any one of 20 different organic molecules that containing both a carboxyl and an amino group and combine to form proteins. |
Codon | A three-nucleotide sequence of DNA or mRNA that encodes a particular amino acid, start signal or termination signal; the basic unit of the genetic code. |
Anticodon | group of three bases on a tRNA molecule that are complementary to an mRNA codon |
