DefinitionTerm
Organelle that uses mRNA to direct the synthesis of a polypeptide
Long chains of amino acid subunits
Enzyme that unwinds DNA
Mutations that only involve one or few base pairs
Currently accepted structure of DNA. Proposed by Watson and Crick
Site where tRNA first bind to mRNA
Corkscrew or coiled spring shaped. DNA structure suggested by Franklin
Stage of gene expression where mRNA is used to direct the production of polypeptides
Enzyme that carries out DNA replication
Experiment that concluded that DNA is the hereditary material
Stage of gene expression where mRNA molecules are synthesized from genes within the DNA
DefinitionTerm
Non-coding nucleotides
Enzyme that covalently bonds nucleotides of new DNA strands after primers have been removed
Pyrimidine base in RNA that replaces Thymine
DNA nucleotide sequences encoding amino acid sequences of a polypeptide
Large bases [adenine, guanine]
New strand that is made in a continuous fashion
Long chains of nucleotides subunits
Three nucleotides unit on mRNA read by the ribosome. Codes for a specific amino acid apart from three exceptions
Copies of genes sent outside the nucleus
Direction by which the leading strand is composed
RNA copy of a gene used in the cell to produce a polypeptide
DefinitionTerm
Determines which amino acid will attach to a particular tRNA
New DNA strand that is assembled in segment
Site where the tRNA is released
Small bases [cytosine, thymine]
Change in the genetic message
Three nucleotide sequence on tRNA that is the complementary sequence to one of the 64 codons of the genetic code
Experiment conducted in 1928 that described the process of transformation
Mutation that throws the reading of the gene message out of register
Enzymes that match amino acids in the cytoplasm with their proper tRNA
The enzyme that makes mRNA
Copying process that makes mRNA
DefinitionTerm
Composed of a sugar, a phosphate group, and an organic base
Experiment that concluded that the genes that viruses use to specify new viruses are made of DNA and not protein
Genetic alteration of a cell by incorporation of DNA taken through the cell wall
Rules that govern genetic translation
Start codon
Path of information. Central dogma
Kind of RNA that binds to the surface of ribosome at the A,P,E binding site
Site where the incoming amino acid of a tRNA forms a peptide bond with the growing polypeptide chain
