Explanation:
Answer:
it depends on the type of the cell.
Explanation:
Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
Answer:
B) spliceosome is a correct answer.
Explanation:
spliceosome performs RNA splicing in eukaryotic cellis.
The spliceosome is the molecular machine, which is present inside the nucleus of the eukaryotic.
spliceosome removes the noncoding region called as intron from the pre-mRNA transcript.
Introns are present in the eukaryotic genes, these introns are removed by the splicesome and the process is called splicing, it results in the formation mRNA through which protein is generated.
Thus correct answer is spliceosome: performs RNA splicing in eukaryotic cell.
