Answer:

Alternative splicing

Explanation:

One gene can lead to multiple proteins by the alternative splicing of the mRNA. The alternative splicing is the most common process that contributes to protein diversity at a pot-transcriptional level. This process is carried out by different combinations of including or excluding exons of the mRNA, obtaining proteins that differ in their amino acids sequence, consequently having different biological functions.

bija089 [108]

Answer:

Permanently ; Transietly

Explanation:

The plasma membrane proteins may be be of two types.

1) Integral proteins; Integral proteins are embedded in membrane because most of integral proteins mostly contain hydrophobic side chain. These proteins are strongly attached to plasma membrane and they can be only removed by using biological detergents, non-polar solvent and denaturing agents.

Example; SMIM23

2) Peripheral proteins; These proteins do not interact with hydrophobic core of membrane. They usually interact with plasma membrane through lipid polar head or integral proteins.

Examples; spectrin, Actin.

satela [25.4K]

Answer:

Explanation:

You might not necessarily be any idiot as you think but what you failed to do before convincing your friends to come to the school was that you did not make appropriate findings if the school, the comfortability of your friends, their needs if then eventually come and transportation. Assuming you make these researches beforehand, you would have know what to to do and won't find yourself in the situation you find yourself now.

It is advisable you make proper, findings before taking a decision. You can still explain the situations to your friends.

Thanks
