Question

question 25 of 25
what is nuclear transfer used for?
a. reverse transcription
b. making insulin
c. creating clones
d. dna fingerprinting

Explanation:

Nuclear transfer is a key technique in cloning. In somatic cell nuclear transfer (SCNT), the nucleus of a somatic cell (like a skin cell) is transferred into an enucleated egg cell. This re - programmed egg can then develop into an embryo that is genetically identical (a clone) to the organism from which the somatic cell nucleus was taken.

• Option A: Reverse transcription is the process of making DNA from RNA, usually by the enzyme reverse transcriptase, and has no relation to nuclear transfer.
• Option B: Making insulin typically involves recombinant DNA technology where the gene for insulin is inserted into bacteria (for example), not nuclear transfer.
• Option D: DNA fingerprinting is based on analyzing variable regions of DNA (such as short tandem repeats) for identification purposes, not nuclear transfer.

Answer:

C. Creating clones
