group of three bases on a tRNA molecule that are complementary to the three bases of a codon of mRNA
One of a ribosome's three binding sites for tRNA during translation. This site is the place where discharged tRNAs leave the ribosome.
Origin of Replication
Site where the replication of a DNA molecule begins, consisting of a specific sequence of nucleotides.
procedure used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and applying an electrical voltage to the gel
Human Genome Project
An international collaborative effort to map and sequence the DNA of the entire human genome.
the normal version of the genetic code in which a sequence of three nucleotides code for the synthesis of a specific amino acid
Joins 3' end of DNA that replaces primer to rest of leading strand and joins Okazaki fragments of lagging strand
The most common type of mutation, a base-pair substitution in which the new codon makes sense in that it still codes for an amino acid.
a specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid
Polymerase Chain Reaction
technique that allows molecular biologists to make many copies of a particular gene
one of a ribosome's three binding sites for tRNA during translation. It holds the tRNA carrying the growing polypeptide chain.
