It is a genetic condition caused when an unusual cell division result in an extra full or even partial copy of chromosome 21. This extra genetic material causes the developmental changes and physical ...

Genetic Basis of Down Syndrome According to Dr Himani Narula Khanna, a developmental behavioural paediatrician and adolescent mental health expert, co-founder of Continua Kids, the genetic basis of ...

Translocations are thus manifested as a change in the length or the banding pattern of a chromosome arm. Over time, cytogeneticists have discovered hundreds, if not thousands, of different human ...

As Figure 2 illustrates, additional subdivisions can be detected in all of the regions on chromosome 12 under these conditions. The Human Genome Project Provides the Ultimate Chromosome Map ...

The presence of three copies of chromosome 21, which harbors the amyloid precursor protein (APP) gene, is the most common genetic cause of Alzheimer’s disease. Carriers of this alteration have Down ...

Still, human males are not going away any time soon. Some experts firmly believe that the Y chromosome will not disappear at all, claiming that it has several defense mechanisms in place.

It is caused by an extra chromosome at chromosome 21. This is not inherited and happens by chance during the formation of egg cells, giving them an extra chromosome (24 total). When fertilised by ...

It’s not clear why these backups have evolved. The new Y chromosome sequences could spell change for metagenomics research, which involves sequencing microbial genomes. Human DNA contaminants often ...

March 21 (3/21) symbolizes the triplication of the 21st chromosome, which causes Down syndrome. This day reminds us to ...
