Cells are complex structures that are made up of many different components, including a cell membrane, cytoplasm, and a nucleus. The cell membrane acts as a barrier, separating…
Mutations are a change in the genetic information in the genome of a cell or a virus. It is a change in the sequence of the DNA, or in the RNA for RNA viruses. This is one of the main causes of the evolution of species and one of the main mechanisms of molecular evolution….
Down syndrome (DS) is a chromosomal disorder that includes a combination of birth defects, including some degree of mental retardation, characteristic facial features and, often, heart defects and other health problems. The severity of these problems varies greatly among affected individuals. What are Chromosomal Abnormalities What are Gene Families and How they Evolved? What are interrupted…
About 1 in every 200 babies is born with a chromosomal abnormality. The syndrome, which causes a baby is born with an extra chromosome 21, is one of the most common chromosomal abnormalities whose effects are known by most people. Children affected with this syndrome have varying degrees of intellectual disabilities, characteristic facial features, and,…
