The structure that produces antibodies is: MCQ with Answer and Explanation

Explanation:
The spliceosome is a large, dynamic complex composed of five small nuclear ribonucleoproteins (snRNPs, pronounced 'snurps') and numerous other protein factors. It assembles on the pre-mRNA transcript in the nucleus. Its primary function is to catalyze the splicing of pre-mRNA: it precisely recognizes the splice sites at the boundaries of introns and exons, removes the non-coding intron sequences, and ligates (joins) the coding exons together to form a continuous, mature mRNA molecule that can be exported to the cytoplasm for translation.

Explanation:
Chlorophyll, mainly chlorophyll a and b, absorbs red and blue wavelengths and reflects green light, giving plants their characteristic color. It is the primary pigment of photosynthesis, located in the thylakoid membranes. Carotenoids reflect yellow-orange, phytochrome is a light-sensing pigment, anthocyanins are red/purple.

Explanation:
African sleeping sickness (trypanosomiasis) is caused by the protozoan Trypanosoma brucei, transmitted by the tsetse fly (Glossina). Malaria is by Plasmodium (Anopheles mosquito), filariasis by Wuchereria (Culex), yellow fever by a virus (Aedes). Sleeping sickness affects the central nervous system, causing lethargy, coma, and death if untreated.
