16 - Binding of an RNA binding protein will the. All of the above. The RNA that is synthesized in this process is then transferred to the cells cytoplasm where it is translated into a protein.

Deleting 3 amino acids from a protein chain Mutating a gene Covalently modifying a base in a mRNA sequence Removing a section of a mRNA sequence. All of the above The correct answer is. Post-transcriptional modification of hnRNA involves all of the following except.

In eukaryotes the primary RNA transcript undergoes structural and chemical changes after transcription to become a mature and functional RNA which is then transported out of the nucleus to perform various functions. A Introns of some tRNA precursors are removed. In this step 7-methylguanosine is added to 5 end of RNA.

Introns are removed from the mRNA. B CCA is added at 3 end. MRNAs in prokaryotes tend to contain many different genes on a single mRNA meaning they are polycystronic.

Post-transcriptional regulation can occur at any stage after transcription including RNA splicing nuclear shuttling and RNA stability. C the excision of introns from mRNA via spliceosome formation. C Mediator Which of the following is not involved in post-transcriptional control.

Capping of eukaryotic mRNAs refers to the addition of 7-Methylguanosine to the 5 end of almost all eukaryotic mRNAs in an unusual 55- triphosphate linkage. Control of RNA shuttling c. Post transcriptional processing of RNA in eukaryotes involves three steps namely capping poly-adenylation and splicing.

Binding of an RNA binding. Post-transcriptional modification is a set of biological processes common to most eukaryotic cells by which an primary RNA transcript is chemically altered following transcription from a gene to produce a mature functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell. Addition of a poly A tail.

A poly-A tail is added to the 3 end of the mRNA. A guanine cap is added to the 5 end of the mRNA. In prokaryotes the RNA that is synthesized during DNA transcription is ready for translation into a protein.

B the addition of a 3 poly-adenine tail. All of the following are considered post- transcriptional modifications that occur in the nucleus EXCEPT A 5 capping with methylated guanines. Please log in or register to add a comment.

Post-transcriptional modifications PTMs are processes that facilitate the generation of mature functional RNA RNA A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. D form base pairs with mRNA molecules.

Addition of a methyl. RNA is unique among biological macromolecules in that it can encode genetic information serve as. RNA molecules can undergo a number of post transcriptional modifications the most prominent of which is methylation.

All of the following are post-transcriptional processing events that convert eukaryotic pre-mRNA into mature mRNA EXCEPT. Post transcriptional processing of RNA in eukaryotes involves three steps namely capping poly-adenylation and splicing. In this step 7-methylguanosine is added to 5 end of RNA.
