DefinitionTerm
Site where the tRNA is released
Change in the genetic message
Path of information. Central dogma
Three nucleotide sequence on tRNA that is the complementary sequence to one of the 64 codons of the genetic code
Currently accepted structure of DNA. Proposed by Watson and Crick
Site where the incoming amino acid of a tRNA forms a peptide bond with the growing polypeptide chain
Corkscrew or coiled spring shaped. DNA structure suggested by Franklin
RNA copy of a gene used in the cell to produce a polypeptide
Enzymes that match amino acids in the cytoplasm with their proper tRNA
New strand that is made in a continuous fashion
Kind of RNA that binds to the surface of ribosome at the A,P,E binding site
DefinitionTerm
Enzyme that covalently bonds nucleotides of new DNA strands after primers have been removed
Stage of gene expression where mRNA molecules are synthesized from genes within the DNA
New DNA strand that is assembled in segment
Rules that govern genetic translation
Large bases [adenine, guanine]

Experiment that concluded that DNA is the hereditary material
Long chains of amino acid subunits
Pyrimidine base in RNA that replaces Thymine
Non-coding nucleotides
DefinitionTerm
Copying process that makes mRNA
Direction by which the leading strand is composed
Experiment conducted in 1928 that described the process of transformation
