Ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA
type of RNA that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
enzyme that links together the growing chain of RNA nucleotides during transcription using a DNA strand as a template
three diferences between RNA and DNA
the sugar strand in RNA is ribose instead of deoxyribose, RNA is generally single-stranded and not double-stranded, and RNA contains uracil in the place of thymine
collection of codons of mRNA, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis
group of three nucleotide bases in mRNA that specify a particular amino acid to be incorporated into a protein
process by which the sequence of bases of an mRNA is converted into the sequence of amino acids of a protein
group of three bases on a tRNA molecule that are complementary to the three bases of a codon of mRNA
process by which a gene produces its product and the product carries out its function
mutation that shifts the "reading frame" of the genetic message by inserting or deleting a nucleotide
chemical or physical agents in the environment that interact with DNA and may cause a mutation
