Multiple choice zoology mutation dna fingerprinting human genome project and dna fingerprinting instruments in biotechnology

DNA probes used in finger printing are

  1. Highly sensitive electron microscope

  2. UV beams

  3. DNA segments having radioactive isotopes

  4. X-ray scanners
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

DNA probes used in fingerprinting are single-stranded DNA segments labeled with radioactive isotopes (or fluorescent markers) to detect complementary sequences on the membrane.

In DNA finger printing, analysis is made of

  1. Satellite DNA

  2. Moderately repetitive sequences

  3. Microsatellites

  4. Variable number of tandem repeats
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

DNA fingerprinting relies on detecting variations in specific repetitive DNA regions. Variable Number of Tandem Repeats (VNTRs) are highly polymorphic sequences used as markers for individual identification.

Process used for amplication or multiplication of DNA for finger printing is

  1. Polymerase chain reaction

  2. Nesslerisation

  3. Southern blotting

  4. Northern blotting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Polymerase Chain Reaction (PCR) is the standard laboratory technique used to amplify small segments of DNA, making them sufficient for analysis in fingerprinting.

The probes for DNA finger printing are

  1. Unknown single stranded labelled DNA

  2. Unknown double stranded labelled DNA

  3. Known single stranded labelled DNA

  4. Known double stranded unlabelled DNA
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Probes used in DNA fingerprinting are known, single-stranded DNA sequences that are radioactively or fluorescently labeled to bind specifically to complementary target sequences on the membrane.
