Exam 14: Rna Processing I: Splicing

Introns are regions found in DNA sequences and mature mRNA sequences.

_______________ disrupting the normal splicing consensus sequence are one way to obtain abnormal splicing patterns.

SC35 is an RNA binding protein that is responsible for the commitment to splice the $\beta$ -globin pre-mRNA.

Which of the following is the name for the Yeast 40S particle where mRNA splicing takes place?

Pre-mRNA splicing occurs in the cytoplasm.

Exon definition involves the use of the ________ subunit of RNA polymerase II.

The discovery of alternate splicing helped prove the "one gene,one protein" theory.

RNA polymerase II does not transcribe through introns,instead it jumps over them.

Which of the following complexes found in the spliceosome cycle is mismatched with its snRNP(s)?

Some introns,such as Group II introns,are self splicing.These types of introns contain catalytic RNA's,also referred to as __________.

The spliceosome cycle is one way for a cell to regulate gene expression.
