Repetitive DNA: DNA sequences that are repeated in the genome. These sequences do not code for protein. One class termed highly repetitive DNA consists of short sequences, 5-100 nucleotides, repeated thousands of times in a single stretch and includes satellite DNA. Another class termed moderately repetitive DNA consists of longer sequences, about 150-300 nucleotides, dispersed evenly throughout the genome, and includes what are called Alu sequences and transposons.
Function of Repetitive DNA. The function of repetitive DNA was illuminated by several lines of genome research during the 1980s. Strong evidence was presented showing that ...
The human genome contains approximately three billion base pairs of DNA. Within this there are between 30,000 and 70,000 genes, which together add up to less than 5 ...
