(genetics) modification of a cell or bacterium by the uptake and incorporation of exogenous DNA
an organic base that contains nitrogen, such as a purine or pyrimidine; a subunit of a nucleotide in DNA and RNA
the rules stating that cytosine pairs with guanine and adenine pairs with thymine in DNA, and that adenine pairs with uracil in RNA
complementary base pair
the nucleotide bases in one strand of DNA or RNA that are paired with those of another strand; adenine pairs with thymine or uracil, and guanine pairs with cytosine
an enzyme that untwists the double helix at the replication forks, separating the two parental strands and making them available as template strands
enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule
in each new DNA double helix, one strand is from the original molecule, and one strand is new
(biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes
the formation of proteins by using information contained in DNA and carried by mRNA
short-chain RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according
enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription
the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
a specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid
