Question

Chimeric DNA is a

• A. Gene clone
• B. Recombinant DNA
• C. DNA which contains uracil
• D. DNA synthesized from RNA

Answer 1

The correct option is B

Recombinant DNA

The correct option is B.

Explanation for correct option:

1. Chimeric DNA is made through a process of genetic recombination, which assists in bringing together genetic material from multiple origins that would not otherwise be found in that particular genome.
2. Recombinant DNA is created through genetic recombination or molecular cloning.
3. They are known to contain genetic components derived from numerous origins, resulting in the formation of a shared genome within the newly created creature.

Explanation for incorrect options:

Option A:

1. A gene clone, also known as a molecular clone, is a replica of an isolated fragment of the desired DNA gene.
2. As a result, this is the incorrect option because there are no sticky ends present.

Option C:

1. There are four types of deoxyribonucleotides in DNA.
2. Deoxyribonucleotides are made up of deoxyribose, phosphoric acid, and a nitrogen base.
3. Adenine and guanine are both 9-membered double ring purines.
4. Cytosine and thymine are 6-membered sing ring pyrimidines.
5. Uracil is found in RNA instead of thymine.

Option D:

1. Complementary DNA is DNA that is produced from a single-stranded RNA (messenger RNA or micro RNA) template in a procedure catalyzed by the enzyme reverse transcriptase (cDNA).
2. It is utilized in prokaryotes to clone eukaryotic genes.

Final Answer: Chimeric DNA is a recombinant DNA.
