Biotype Rh-negative is a Basque biotype. This type has inherited a Basque gene for blood type Rh-negative from ancient ancestors in the Pyrenees Mountains of France and Spain. Their ancestors adapted to their specific ecosystem over long periods of time in isolation, and modern Rh-negatives have inherited those adaptations.
You will find the chromosomes and genetic material in the nucleus of a cell. In prokaryotes, DNA floats in the cytoplasm in an area called the nucleoid. Chromosomes are not always visible. They usually sit around uncoiled and as loose strands called chromatin. When it is time for the cell to reproduce, they condense and wrap up very tightly. The tightly wound DNA is the chromosome. Chromosomes look kind of like long, limp, white hot dogs.
Making the world better, one answer at a time. The double helix of the DNA unwinds. Then, the enzyme helicase 'unzips' the DNA by breaking the hydrogen bonds. Then, the enzyme DNA Polymerase pairs each of the two strands with the correct nitrogenous bases.The top strand is called the 'leading strand' and the bottom strand is called the 'lagging strand.' Then the enzyme ligase glues together the different fragments of the lagging strand of DNA.Now we have two exact replications of DNA, each with 46 chromosomes called daughter cells.he top strand is called the 'leading strand' and the bottom strand is called the 'lagging strand.'
