During the process of replication, the double stranded DNA unwinds and parts itself by the action of enzyme called as Helicase. The unwinding or separation of DNA forms a replication bubble and at the edge of the replication bubble is the replication fork.
DNA replication starts at the point called as origin of replication or ORI at the replication fork. DNA polymerase is the enzyme that plays a key role in DNA replication. DNA continues to replicate until the entire new strand is not formed.
The arrangement of the autosomes and that of sex chromosomes in the pairs is known as karyotype.
A karyotype test looks at the size, of the shape, and the number of your chromosomes. the Chromosomes are the parts of your cells that has contain your genes. Genes are the parts of the DNA passed down from your mother and the father. They also carry the information that determines your unique traits, such as the height and the eye color.
A karyotype test also examines the blood or the body fluids for the abnormal chromosomes. It's is often used to detect the genetic diseases in unborn babies still the developing in the womb.

Triglycerides are formed by combining glycerol and three fatty acids. Specifically, the hydroxil groups of the glycerol join the carboxyl group of the fatty acid to form ester bonds.
Phospholipids are made up of two fatty acids namely: long chains of hydrogen and carbon molecules and they are attached to the glycerol "head".
Based on their individual structure, the difference between the two is the number of fatty acids they both contain. Triglycerides has three fatty acids while phospholipids only have two.
