Answer 1

1.

The use of DNA analysis to identify individuals is known as :-

The correct answer is (b) DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.

(a) is wrong answer, because it has written pcr testing instead of dna dna fingerprinting.

(c) is wrong answer because it has written cloning instead of dna fingerprinting.

(d) is wrong answer because it has written none of these while answer is available in option.

2.

DNA identification of individuals is possible because :-

(a) is correct answer because It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother.

(b) is wrong answer because it has written a different restriction enzyme is needed to cut each person’s DNA.

(c) is wrong answer because it has written a different species of bacteria is needed for the DNA library of each person.

(d) is wrong answer because it has written each person’s DNA uses a different set of bases.

3.

Which of the following sources would NOT be suitable for DNA fingerprinting analysis :-

(d) is correct answer because Red blood cells do not have any DNA, as they lose their nuclei.

(a) is wrong answer because it has written saliva.

(b) is wrong answer because it has written hair.

(c) is wrong answer because it has written semen.

(e) is wrong answer because it has written urine.

4.

Small circular DNA molecules accompanying the main DNA of the bacterial chromosome in a bacterial cell are called :-

(d) is correct answer because A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.

(a) is wrong answer because it has written jumping genes.

(b) is wrong answer because it has written ligases.

(c) is wrong answer because it has written polymerases.

5.

Procedures that manipulate the genes of organisms are referred to as :-

(c) is correct answer because Genetic engineering, also called Genetic modification or Genetic manipulation, is the direct manipulation of an organism's genes using biotechnology.

(a) is wrong answer because it has written dna fingerprinting.

(b) is wrong answer because it has written bacteriophages.

(d) is wrong answer because it has written new genetics.

6.

Your child is taking an antibiotic that blocks ribosomes in the pathogenic (disease-causing) bacteria from binding with mRNA. Which of the following processes will not occur in the pathogenic bacteria :-

(c) is correct answer because if ribosome will not bind with mrna , translation will not occur.

(a) is wrong answer because it has written transcription.

(b) is wrong answer because it has written photosynthesis.

(d) is wrong answer because it has written osmosis.
