The human genome was first deemed complete in 2000, but this was not the case—it wasn't until May 2021 that scientists mapped the entire genome.Summary
This article makes the following points:
- Previous studies have mapped over 90% of the human genome.
- New technology has permitted scientists to complete the human genome—3.055 billion letters across 23 chromosomes.
- A group of scientists worldwide known as the public consortium have continued to work on mapping the human genome.
- Chromosomes consist of a long stretch of DNA, and each chromosome has a centromere.
- The centromere is close to one end on five chromosomes, resulting in one long and one short arm.
- Short arms are full of repeating regions.
- Centromeres and short arms make up most of the 238 million letters added to complete the genome.
- The role of centromere sequences is cell division.
- The Consortiums’ next goal is to map a human cell of 23 pairs of chromosomes, known as a diploid genome.
