6
Rare cutter is
Discuss
Answer & Solution
Answer: Option D
Solution:
1. Rare cutters are restriction enzymes that recognize longer and less frequent sequences in DNA.
- These enzymes cut DNA at specific recognition sites, usually 6 to 8 base pairs long.

2. Eco R I is a rare cutter.
- It recognizes the specific sequence 5'-GAATTC-3', which occurs less frequently in the genome compared to shorter recognition sequences.

3. Rare cutters are useful in genome mapping and cloning.
- They generate larger DNA fragments, making them ideal for analyzing larger genomic regions.

4. Options like Hae III and Alu I are frequent cutters.
- They recognize shorter sequences and cut more frequently, producing smaller fragments.

5. Option D is correct as Eco R I is classified as a rare cutter due to its longer recognition sequence.

9
During splicing of proteins which part is removed
Discuss
Answer & Solution
Answer: Option D
Solution:
1. Splicing of proteins refers to the process where specific sequences within a protein are removed and the remaining parts are joined together.

2. Inteins are the parts removed during protein splicing.
- They are internal protein sequences that excise themselves from a precursor protein.

3. Exteins are the remaining protein sequences.
- These sequences are joined together to form the functional protein after the removal of inteins.

4. Protein splicing is an autocatalytic process.
- It does not require external enzymes and occurs naturally in some organisms.

5. Option D is correct because inteins are removed during protein splicing, leaving exteins to form the final protein.
