Question

How is repetitive / satellite DNA separated from bulk genomic DNA for various genetic experiments?

Answer 1

Density-gradient centrifugation is the technique used for the separation of satellite DNA from bulk genomic DNA for various genetic experiments.

• Most of the satellite DNA consists of repeated nucleotide sequences or short DNA sequences.

• These are separated by density gradient centrifugation method.

• Density-gradient centrifugation is invented by the scientists Myron Brakke.

• In this technique, the DNA particles are separated based on the rate of sedimentation.

• The sedimentation rate depends upon the particle size, shape and thickness.

Answer 2

Repetitive/satellite DNA separation

Explanation:

• There are regions in a DNA sequence called repetitive DNA on the grounds that these successions have a little stretch of DNA that is rehashed commonly.
• These monotonous/satellite DNA are isolated from mass genomic DNA in a type of various tops by the procedure of thickness angle centrifugation.
• The mass DNA right now a significant pinnacle and the other little pinnacles shaped are called satellite DNA.
