How does replicative transposition differ from cut-and-paste transposition?
Replicative transposition is faster than cut-and-paste transposition. Replicative transposition results in multiple copies of the transposon in the DNA; cut-and-paste transposition has only one copy. Replicative transposition makes use of the enzyme transposase; cut-and-paste transposition does not.
What kind of recombination events are involved in transposition?
Transposition of an element is thus a recombination reaction involving three separate sites: the two transposon ends and the new target locus. In autonomous transposable elements, the transposase is encoded by a gene located within the element.
What is required for transposition?
Transposition requires that each element end contain recombination sites which define the DNA segment which will be moved during transposition. The terminal recombination sites are organized as inverted repeats so that the recombination proteins are positioned in symmetrical fashion at each end.
What role does RNA splicing play in the final protein expression of an antibody light chain gene?
What role does RNA splicing play in the final protein expression of an antibody light chain gene? Splicing joins the C (constant) coding region to a pair of rearranged V and J gene segments.
What do B cells use alternative splicing for?
B cells express an antigen-specific and clonally restricted receptor known as an immunoglobulin (Ig) molecule or B cell receptor (BCR). Alternative pre-mRNA splicing can also regulate protein expression in a cell-specific or tissue-specific manner in response to precise environmental or developmental cues.
Why alternative splicing is important?
Alternative splicing is one of the most important mechanisms to generate a large number of mRNA and protein isoforms from the surprisingly low number of human genes.
What is the process of alternative splicing?
Alternative splicing is the process of selecting different combinations of splice sites within a messenger RNA precursor (pre-mRNA) to produce variably spliced mRNAs. These multiple mRNAs can encode proteins that vary in their sequence and activity, and yet arise from a single gene.
What is an example of alternative splicing?
Collectively such genes are considered to undergo complex alternative splicing. The best example is the Drosophila Down syndrome cell adhesion molecule (Dscam) gene, which can generate 38,016 isoforms by the alternative splicing of 95 variable exons.
What is meant by splicing?
(SPLY-sing) The process by which introns, the noncoding regions of genes, are excised out of the primary messenger RNA transcript, and the exons (i.e., coding regions) are joined together to generate mature messenger RNA. The latter serves as the template for synthesis of a specific protein.
How many types of splicing are there?
There are two types of fiber splicing – mechanical splicing and fusion splicing. Mechanical splicing doesn’t physically fuse two optical fibers together, rather two fibers are held butt-to-butt inside a sleeve with some mechanical mechanism.
