Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
Answer:
RNA splicing is the intron removal and exon binding in the mRNA before leaving the nucleus.
Explanation:
Alternative splicing of identical RNA transcripts into different cell types can produce different mature mRNA molecules that translate into different polypeptides.
The genetic information encoded in the AND is transcribed to a copy of RNA (primary transcript). This copy is then modified with the addition of the 5 ’cap (CAP) and the poly-A tail, the excision of the introns and the union of the exons (splicing). The mature mRNA then goes to the cytoplasm, where it is translated into proteins.
