Answer: Lk for this plasmid = 47
Explanation:
The formula to compute Lk is given by :-
Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)
Given: A plasmid 41 twists and 6 right handed writhes.
i.e. Twist (Tw) = 41 , Writhe (Wr) = 6
Then, Topological Linking Number (Lk) for this plasmid : = 41+6
= 47
Hence, the Lk for this plasmid = 47

(a) deletion(b) inversion (c) duplication(d) insertion
Answer: (d) insertion
This mutation occurs when (an) additional nucleotide base pair/s attach themselves into an existing DNA strand. This can possibly result to diseases such as cystic fibrosis and myotonic dystrophy.
Reduce osteoblast activity while boosting osteoclast activity
osteoblast:
- Untreated celiac disease has a number of potential side effects, including the failure for children to reach their ideal bone density and adult bone loss, both of which raise the risk of osteoporosis. Following a gluten-free diet is the only way to treat celiac disease.
- As a result, celiac disease is common in both children and adults with low bone density. When celiac disease is discovered in an adult, the risk of osteoporosis is very significant (because they have gone longer without absorbing enough calcium and other nutrients).
- Osteoporosis is a bone disease that appears when bone mass, bone mineral density, or both drop or when the quality or structure of the bone deteriorates. This may result in a loss of bone density and an elevated risk of fractures (broken bones).
