Genetic fingerprinting – the analysis of DNA in order to identify the individual from which the DNA was taken to establish the genetic relatedness of individuals. It is now commonly used in forensic science (for example to identify someone from a blood sample) and to determine whether individuals of endangered species in captivity have been bred or captured from the wild.
<span>•DNA sequencing – the determination of the precise sequence of nucleotides in a sample of DNA or even a whole genome e.g. the Human Genome Project. </span>
<span>The process of electrophoresis: </span>
<span>DNA is chopped, close to the VNTR regions, into fragments using restriction enzymes. The DNA fragments are placed on the agarose gel and a direct current is applied continuously to the gel. The DNA fragments are attracted to the anode. The shorter the fragment, the faster it moves. </span>
<span>The fragments are transferred onto an absorbent paper placed on top of the gel. The paper is heated to separate the 2 strands in each DNA molecule. Complementary probes which have a radioactive phosphorus isotope are and this pair up with the DNA strands. The paper is placed on an X-ray film and the film goes dark due to radiation emitted by the probes. Now we end up with a pattern of dark stripes on the film matching the positions reached by the fragments in the agarose gel.</span>
The water may be polluted and the wetness of the dirt may not be suitible for numerous plants
Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Other Info That Might Help:
In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.
