DefinitionTerm
Three nucleotide sequence on tRNA that is the complementary sequence to one of the 64 codons of the genetic code
DNA nucleotide sequences encoding amino acid sequences of a polypeptide
Large bases [adenine, guanine]
Organelle that uses mRNA to direct the synthesis of a polypeptide
Stage of gene expression where mRNA is used to direct the production of polypeptides
Pyrimidine base in RNA that replaces Thymine
Non-coding nucleotides
Mutation that throws the reading of the gene message out of register
Determines which amino acid will attach to a particular tRNA
Copying process that makes mRNA
Change in the genetic message
DefinitionTerm
New DNA strand that is assembled in segment
Path of information. Central dogma
Experiment that concluded that the genes that viruses use to specify new viruses are made of DNA and not protein
New strand that is made in a continuous fashion
Enzyme that covalently bonds nucleotides of new DNA strands after primers have been removed

Copies of genes sent outside the nucleus
Experiment conducted in 1928 that described the process of transformation
DefinitionTerm
Enzyme that unwinds DNA

Start codon
Site where the incoming amino acid of a tRNA forms a peptide bond with the growing polypeptide chain
Three nucleotides unit on mRNA read by the ribosome. Codes for a specific amino acid apart from three exceptions
RNA copy of a gene used in the cell to produce a polypeptide
Composed of a sugar, a phosphate group, and an organic base
The enzyme that makes mRNA

Small bases [cytosine, thymine]
Stage of gene expression where mRNA molecules are synthesized from genes within the DNA
DefinitionTerm
Rules that govern genetic translation
Site where tRNA first bind to mRNA
Kind of RNA that binds to the surface of ribosome at the A,P,E binding site
