cells from maternal blood with the aim of developing a non-invasive risk free form of prenatal diagnosis. By using the then novel Magnetic Activated Cell Sorting (MACS) we were among the first to detect fetal aneuploidies. The efficacy of t...
strands and starts at specific sites of the double helix called origins of replication. Each of these strands serves as a template to assemble a new, complementary strand. The result of DNA replication is two identical double-stranded molec...
acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin...
DNA contains the genetic code that makes us all very unique. Our growth, sex, hair, eye color and other personal features contribute to the differences in the code. 50% of our DNA is inherited from each parent. Brothers and sisters are more...
of mitosis, growth and recovery. Some cells once entirely shaped do not suffer cell division, such as nerve cells in addition to muscle cells. Since you can not re-grow or repair of these types of cells when they are mature, you have to ta...
DNA are adenine, thymine, guanine, and cytosine. The sugar group that is attached to the sugar-phosphate backbone is deoxyribose. Each nucleotide will link to another corresponding nucleotide in the DNA molecule, A with G, T with C, etc. (A...
DNA first came into use for forensic science in 1986. It was used by a scientist by the name of Alec Jeffreys and his colleagues from Leicester University. He was contacted by authorities to verify the confessions by a seventeen year old po...
