Question

Full form of CRISPR, a term used in genome editing is -

• A. Clustered regularly inter spaced short palindromic repeats
• B. Cumulative routinely inter spaced short palindromic repeats
• C. Cumulative regularly inter spaced short palindromic repeats
• D. Clustered routinely inter spaced slight palindromic repeats

Hint:

To remember the full form, break it down and understand what each word means in the context of DNA sequences. This makes it easier to spot the incorrect words in distractor options.

Answer 1

The Correct Option is A

Step 1: Concept Overview:
This question tests knowledge of the CRISPR acronym's full name, a key gene-editing tool.
Step 2: In-Depth Explanation:
CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats.
This term refers to a specific DNA area in bacteria and archaea.
Clustered: The repeats are grouped.
Regularly Interspaced: Repeats are separated by unique "spacer" sequences.
Short: Repeats are brief in length.
Palindromic: Repeats read the same forward and backward on opposite DNA strands.
Incorrect answer choices use similar-sounding words like "Cumulative," "routinely," and "slight" as misleading options.
Step 3: Correct Answer:
The complete expansion is Clustered regularly inter spaced short palindromic repeats.
