The cells that transmit nerve impulses in the nervous system are called: MCQ with Answer and Explanation

The cells that transmit nerve impulses in the nervous system are called:
A. Neurons
B. Glial cells
C. Epithelial cells
D. Fibroblasts
Answer: Option A
Solution (By JKSSB Mock Tests)
Neurons are the excitable cells that generate and transmit electrochemical impulses. Glial cells (neuroglia) provide support, insulation, and nutrients. Fibroblasts form connective tissue, epithelial cells line surfaces. The neuron is the functional unit of the nervous system, connected at synapses.

Question #2
A virus particle (virion) consists of genetic material enclosed in a protein coat called:
A. Capsid
B. Cell wall
C. Envelope
D. Plasmid

Correct Answer: Option A


Explanation:
A virus is an obligate intracellular parasite. The basic structure of a virus particle, or virion, consists of genetic material (either DNA or RNA, but never both) enclosed in a protective protein coat called a capsid, made of subunits called capsomeres. Some viruses also have an outer lipid envelope derived from the host cell membrane.

Question #3
The technique used to analyze the transcriptome of a cell is:
A. Genomics
B. Transcriptomics
C. Proteomics
D. Metabolomics

Correct Answer: Option B


Explanation:
Transcriptomics studies the complete set of RNA transcripts (transcriptome) produced by the genome under specific conditions. It often uses microarrays or RNA-seq. Genomics is DNA, proteomics proteins, metabolomics metabolites.
