The methodologist of human genome project it focused on two main lines i.e. expressed sequence tags and sequence annotation. The genetic and physical maps of the genome were constructed by collecting information about certain repetitive DNA sequences and DNA polymorphism. VNTR or variable number of tandem repeat belongs to a class of satellite DNA called minisatellite. They are used as probes in DNA finger printing.

What is the criterion for DNA fragments movement on agarose gel during gel electrophoresis?
1 The larger the fragment size, the farther it moves
2 The smaller the fragment size, the farther it moves
3 Positively charged fragments move to farther end
4 Negatively charged fragments do not move
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. - DNA samples are loaded into wells (indentations) at one end of a gel, and electric current is applied to pull them through the gel. - DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragment move through the gel faster than large ones. - When a gel is stained with a DNA binding dye, the DNA fragments can be seen as bands, each representing a group of same sized DNA fragments.

What is it that forms the basis of DNA fingerprinting?
1 The relative amount of DNA in the ridges and grooves of the fingerprints
2 Satellite DNA occurring as highly repeated short DNA segments
3 The relative proportions of purines and pyrimidines in DNA
4 The relative difference in the DNA occurrence in blood, skin and saliva
Explanation:
DNA that contain number of repetitive short DNA sequences is known as satellite DNA or tandemly repeated DNA. - DNA fingerprinting is a technique that is used to identify the nucleotide sequence in the specific region of sample DNA. - Fingerprinting identification is the analysis of physical prints of finger on surface; it does not include DNA study. - Alec Jeffrey developed this technique in which he used satellite DNAs also called VNTRs (Variable Number of Tandem Repeat).

Which is also called molecular glue
1 DNA gyrase
2 DNA helicase
3 DNA ligase
4 DNA polymerase
Explanation:
DNA ligase is a specific type of enzyme, that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. - DNA ligase is commonly known as molecular glue.
