Q:

Atomic force microscopy uses _____________

A) X-rays B) Infrared light
C) Nanosized tip D) Nickel tip
 
Answer & Explanation Answer: C) Nanosized tip

Explanation: Atomic force microscopy is a type of high resolution scanning probe microscopy that uses the nanosized tip to probe the surface of a macromolecule. Researchers have used this technique to study intermediate filaments.

Q:

Proto-oncogenes are possessed by the ______________________

A) RNA virus B) DNA virus
C) Cells themselves D) Pathogenic bacteria
 
Answer & Explanation Answer: C) Cells themselves

Explanation: Proto-oncogenes are the genes present in cells themselves, these genes have the ability to avert a normal cell into a cancerous one. The initial event that led to the discovery of proto-oncogenes was made in 1976 when src gene from avian sarcoma virus was identified.

Q:

Which of the following is not true for both prokaryotic and eukaryotic cells?

A) Same composition of plasma membrane B) Both contain shared metabolic pathways
C) Genetic information encoded in DNA with similar genetic code D) Both contain Golgi apparatus for protein trafficking
 
Answer & Explanation Answer: D) Both contain Golgi apparatus for protein trafficking

Explanation: Prokaryotic cells do not have organelles such as Golgi Apparatus. However, the composition of plasma membrane is the same. The metabolic pathways such as TCA cycle and glycolysis take place in both. Both contain DNA as the genetic material.

Q:

Which of the following cell organelle is responsible for transporting, modifying, and packaging proteins and lipids?

A) Mitochondria B) Endoplasmic Reticulum
C) Golgi Complex D) DNA
 
Answer & Explanation Answer: C) Golgi Complex

Explanation: The Golgi apparatus, also known as the Golgi complex, is a factory where proteins from the ER are further processed and sorted before being transported to their final destinations: secretion, lysosomes, or the plasma membrane.

Q:

Which of the following organisms doesn’t have a cell?

A) Virus B) Bacteria
C) Fungi D) Algae
 
Answer & Explanation Answer: A) Virus

Explanation: Viruses aren’t made up of cells. Their genetic material is protected by a protein covering (either DNA or RNA). However, they lack a cell membrane and other organelles seen in cells.
