Enzyme required for transcribing genetic information of DNA into RNA is

Options:
A DNA dependent DNA polymerase
B DNA dependent RNA polymerase
C RNA dependent RNA polymerase
D Both a and b

The correct answer is:
DNA dependent RNA polymerase

Solution:
Protein synthesis is the process of manufacturing protein from DNA involving two steps - transcription and translation. Transcription is the process of making mRNA from the DNA and this mRNA is translated into a long chain polypeptide with help of ribosome and tRNA. The strand of DNA from which the new mRNA is synthesized is called as template strand or non-coding or anti-sense strand. It is in the 3' → 5' direction. The mRNA is synthesized on it in the 5' → 3' with the help of DNA dependent RNA polymerase enzyme which leads in the same direction.

Epithelial cells of the intestine involved in food absorption have on their surface:

Options:
A pinocytic vesicles
B microvilli
C zymogen granules
D phagocytic vesicles.

The correct answer is:
microvilli

Solution:
In the small intestine, the cells contain microvilli, which are tiny hair-like projections that increase nutrient absorption. These projections increase the surface area of the small intestine allowing more area for nutrients to be absorbed. Zymogen granules are specialized storage organelles in organs that secrete digestive enzymes that allow the sorting, packaging and regulated apical secretion of the enzymes. Pinocytosis is a mode of endocytosis in which liquid droplets are brought into the cell, forming an invagination, and then suspended within small vesicles. Phagocytic vesicles are membrane-bound intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.
Caution
Zymogen (chief) cells produce the enzymes pepsin and rennin. (Pepsin digests proteins, and rennin curdles milk.)
