Approximately what percentage of the human genome is composed of repetitive sequences?
Arturiano [62]
Approximately 50% of human genome is composed of repetitive sequences. It contains approximately 3 billion of these base pairs that reside with 23 pairs of chromosome within the nucleus or our cells or called nucleotides. Genes in the genomes of invertebrates such as Drosophila is not like the human genes because the human genes contain more and larger introns than the genes in the genomes. The human genes are larger than the genes in the genomes. The genome sequence is ~99.9% similar in individuals of all nationalities. Complete set of deoxyribonucleic acid of a single cell of an organism or sequence for humans (Homo sapiens) is called Genome. It includes both protein-coding deoxyribonucleic acid genes and noncoding deoxyribonucleic acid.
