The document discusses the composition and functions of the spliceosome, which is a complex molecular machine made up of small nuclear RNAs (U1, U2, U4, U5, U6) and associated protein factors. It highlights the role of spliceosome in RNA-RNA and RNA-protein interactions, as well as the significance of the multiprotein complex and major histocompatibility complex (MHC) in antigen presentation and molecular degradation. The MHC specifically binds antigens from pathogens for recognition by T cells.

Explain the make up and role of different complexes: for example the components of the
spliceosome made up and its role.
Solution
Answer=1]
components of spliceosome made up &its roles
Spliceosome is large & compex molecular machine
assembled from snRNAs & protein complexes
1] sn RNAs = it is composed of 5 small nuclear RNAs
are U1,U2,U4,U5 ,U6
Roles - they participate in most RNA -RNA & RNA -Protein interactions
2] associated protein factors = snRNPs or small nuclear ribonucleoproteins
are RNA protein complexes that combine with unmodified mRNA & various other proteins to
form spliceosome
2] Multiprotein complex = is a group of 2 or more associated polypeptide chains
example -proteasome - important for molecular degradation
3] Major histocompatibility compex (MHC )=set of cell surface proteins
role- to bind antigen derived from pathogens & display them on the call surface for recognition
by appropriate T cells](https://image.slidesharecdn.com/virology-230708112135-6a17d5be/85/Virology-Explain-the-make-up-and-role-of-different-complexes-for-pdf-1-320.jpg)
