Chromosome number varies from one organism to another. or example, humans have 46 chromosomes while bacteria have only one chromosome.
The problem associated with the chromosome number of various organisms faced by evolutionists is that with the decrease in the size of an organism, the number of chromosomes also decrease. Thus, it becomes difficult to find and study the chromosomes.
D bacteria are the main nitrogen transporters
DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.
<h3>What is centrifugation?</h3>
Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.
It is the frequently applied techniques in the molecular biology laboratory.
The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.
Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.
