Science / Genetics / Endonuclease: An enzyme that cleaves its nucleic acid substrate at internal sites in the nucleotide sequence.
Science / Genetics / Endonuclease Restriction Enzyme: A protein that recognizes specific, short nucleotide sequences and cuts dna at those sites. Bacteria contain over 400 such enzymes that recognize and cut more than 100 different dna sequences. MORE
Science / Genetics / Alu Repetitive Sequence: The most common dispersed repeated dna sequence in the human genome accounting for 5% of human dna. The name is derived from the fact that these sequences are cleaved by the restriction endonuclease a MORE
