Proteins are processed and modified in the interior of the

Explanation:

The network of membrane-enclosed tubules and sacs with an interconnecting network that is responsible in protein synthesis is called reticulum.

The ER becomes flattened as it spreads throughout, it helps in carrying out a lot of protein synthesis.

The ER are of 2 types:

The rough ER: The outer surface is covered by large number of ribosomes and is responsible in production of proteins.

The smooth ER: It is not connected with ribosomes and is responsible in functioning lipid instead of production of protein, metabolism.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:
