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: Understanding the Concept:
This is a factual recall question asking for the correct expansion of the acronym CRISPR, which is a powerful gene-editing technology.
Step 2: Detailed Explanation:
The acronym CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats.
This name describes a specific region in the DNA of bacteria and archaea.
Clustered: The repeat sequences are found grouped together.
Regularly Interspaced: These repeats are separated by unique sequences called "spacers."
Short: The repeat sequences are brief.
Palindromic: The repeat sequences read the same forwards and backwards on opposite DNA strands.
The other options use similar-sounding but incorrect words like "Cumulative," "routinely," and "slight" to serve as distractors.
Step 3: Final Answer:
The correct full form is Clustered regularly inter spaced short palindromic repeats.
