One, two, and four. Hope this helps!
Answer:
The correct answer is - A and D.
Explanation:
Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.
It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.
Definition. Applied microbiology is a scientific discipline that deals with the application of microorganisms and the knowledge about them. Applications include biotechnology, agriculture, medicine, food microbiology and bioremediation.

Answer:
Nucleus
:
Holds DNA and all the components of proteins.
All Eukaryotic cells have a nucleus and the rest of the membrane-bound organelles
Prokaryotic cells have no nucleus
Ribosomes
:
Take the amino acids and package them into protein chains.
Ribosomes are on the outside of the endoplasmic reticulum
Endoplasmic Reticulum
:
Organelle that transports the completed protein within the cell
Golgi Apparatus
Transports the completed protein from the ER to the outside of the cell. Vesicles carrying the proteins break off the Golgi apparatus moving the proteins outside of the cell
Plasma Membrane
Selectively permeable membrane that allows passage of many materials into and out of the cell.
Transport proteins on the surface help send out messenger proteins to other cells.
Explanation:
Once proteins leave the cell they will be received by another cell. In this way, cells are able to communicate with each other. All cells have protein receptors on them which recognize specific proteins.
