Ans: The Piedmontese MSTN missense mutation G938A is translated to C313Y myostatin protein. This mutation alters MSTN function as a negative regulator of muscle growth, thereby inducing muscle hypertrophy. MiRNAs could play a role in skeletal muscle hypertrophy modulation by down-regulating gene expression.
Streptococcus pyrogenes : Round (or) Ovoid
Paenibaccilus polymyxa:
Aquaspirillum bengal: Helical
Explanation:
- Streptococcus pyogenes are gram positive, Round shaped, Anaerobic growth bacteria, Non-motile bacteria.
- Aquaspirillum bengal is helical in shape with its composition of deoxyribonucleic acid and cytosine. It is Gram negative and chemo-organotrophic. It is also motile with the help of flagella.
- Paenibacillus polymyxa is also known as Bacillus polymyxa which is capable of fixing nitrogen. It is found in soil, plant tissues and marine sediments. It has a major role in forest ecosystems and potential future applications as a biofertilizer and biocontrol agent in agriculture.
