Question

Alternative splicing means:
A.) The same gene can code for several differentproteins. B.) Several different genes can code for the sameprotein. C.) Gene expression can be regulated at the level oftranscription. D.) Pieces of DNA can move around within the genome.
To stimulate transcription, enhance sequences:
A.) Must be within a few base pairs of the gene theyenhance. B.) Must be within a few hundred base pairs of the gene theyenhance. C.) Can be tons of thousands of base pairs away from the genesthey enhance. D.) Will not function if they are moved experimentally.

Explanation / Answer

      Alternativesplicing means:       A.) Thesame gene can code for several different proteins.       Splicing is a mechanismseen in eukaryotes where the exons are flanked together by removingthe introns.       Intron sequence is thenon-expressed region of the DNA while exons is the expressedregion.       In alternative splicing,the exons of the RNA that are produced by transcription arerejoined in multiple ways during       RNA splicing.       This results in differentRNA's that will be translated to different isoforms ofproteins.       Therefore, a single genemay code for multiple proteins.       A.)

Canbe tons of thousands of base pairs away from the genes theyenhance.       An enhancer is a sequenceof DNA that enhances the transcription level of a gene.       To act on a gene, it neednot be close to the genes it acts on and also need not be onthe same chromosome.       It can be located eitherupstream or down stream of the gene it regulates and need not benear the transcription       initiation site.       They will be bound toseveral thousand base pairs upstream or down stream of the startsite.              Hope you are satisfiedwith the answer.       C.)
