Homework Answers
a) miRNA splicing
Self spilicng also known as autocatalytic occurs in miRNA which leads to pre-mRNA which once again undergoes self splicing by sRNPs formed by snRNA along with other associated proteins.

Which statement about mRNA splicing is not accurate? Splicing is carried out by tRNA and associated proteins The C-terminal tail domain of RNA polymerade coordinates the processing (including splicing) of mRNA. The 2’ –OH in ribose is used during the splicing reaction. Alternative splicing can produce different proteins from the same genetic sequence in DNA Which describes the cellular role of chaperone proteins? Guide nascent proteins to their final destination in the cytoplasm Help nascent proteins fold into proper tertiary...
