We know Homo sapiens started in Africa, but we're uncertain about how they spread. Limited fossils and data have hindered our understanding. I'll discuss popular theories about our origins and how recent genetic data from Khoe-San people in southern Africa sheds light on this. Our research su...
The study aimed to compare the knowledge and attitudes of cancer patients presenting to oncology clinics at The American University of Beirut Medical Center before and after watching a short educational video that clarifies the concepts of genetic mutations, genetic testing technique, and its purposes....
Mutation Mutations in body cells Mutation not passed on to offspring, but could cause problems for the individual Skin cell may lose elasticity, when the cell divides, daughter cells also lack elasticity If mutation affects cell division, can cause cancer Types of Mutation Point mutation – change...
In addition to “loss-of-function” mutations that disrupt a gene’s activity, genetic screens can also be based on “gain-of-function” mutations, which cause a gene’s expression or functionality to increase. This can be achieved by randomly inserting gene regulatory elements into the genome...
Leveraging her expertise as a physician-scientist, Yiu explores how CRISPR and other precision gene-editing tools can correct genetic mutations at the cellular level, potentially restoring T-cell production and immune resilience in patients with CD3δ SCID. Her presentation underscores the...
Subsequent endonuclease treatment of DNA from TALEN-treated mice allowed researchers to identify animals with mutations in both copies of the targeted gene. Finally, genome editing can be used to create large genetic deletions by causing two double-strand breaks in the same chromosomal region. These...

Genetic testing, also known as genetic screening, is used to detect disease-related genotypes, mutations, phenotypes or karyotypes that can be passed from parents to offspring. Most genetic tests, whether prenatal or postnatal, are performed by obtaining a blood sample. These tests are important ...
97.8K Views. Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked. Y chromosome mutations are called “Y
