Introduction: Deoxyribonucleic acid (DNA) is the hereditary material that contains the essential genetic information of an organism. The defects that occur in the DNA can be rectified by various methods of
Answer to Problem 1MC
Correct answer: Option a. “produces many copies of specific DNA sequences.”
Explanation of Solution
Reason for the correct answer:
Option a. is given as “produces many copies of specific DNA sequences.”
The polymerase chain reaction (PCR) is the maximum used method for manipulating DNA. Specific amplification of particular DNA sequence produces numerous copies of desirable DNA sequences in this method.
Hence, option a. is correct.
Reasons for incorrect answers:
Option b. is given as “is a method for sequencing DNA.”
DNA sequence is the method of determining the
Hence, option b. is incorrect.
Option c. is given as “is a technique for editing a genome.”
Genome editing is the process of deleting, replacing, or inserting a DNA sequence in order to manipulate the genome of an organism. The PCR is not a technique for genome editing.
Hence, option c. is incorrect.
Option d. is given as “is used to determine whether a specific gene is expressed.”
Gene expression is determined by microarrays and targeted RNA and it cannot be determined using the PCR.
Hence, option d. is incorrect.
Hence, options b., c., and d. are incorrect.
Numerous copies of specific DNA sequences are produced using the PCR.
