Which three post-transcriptional modifications are often seen in the maturation of mRNA in eukaryotes?
These modifications are 5′ capping, 3′ polyadenylation, and RNA splicing, which occur in the cell nucleus before the RNA is translated.
What are the post-transcriptional modifications taking place in mRNA?
Post-transcriptional modifications of pre-mRNA, such as capping, splicing, and polyadenylation, take place in the nucleus. After these modifications have been completed, the mature mRNA molecules have to be translocated into the cytoplasm, where protein synthesis occurs.
Which of the following post-transcriptional modifications are common in eukaryotes?
Which one of the following types of post-transcriptional modification is common in eukaryotes? Polyadenylation, intron removal, & 5′ cap addition.
What does post-transcriptional modification of eukaryotic mRNA include IB?
What does post-transcriptional modification of eukaryotic mRNA include? Exons are joined together to form mature mRNA. III. A 5′ cap and 3′ poly-A tail are added to mRNA.
Which of the following includes the three post transcriptional modifications?
The three post-transcriptional modifications are: 5′ capping, poly A tail addition, and splicing. Problem : What is the function of the 5′ cap in eukaryotes? The 5′ cap helps in eukaryotic mRNA recognition by ribosomes during translation.
Do transcription factors help move ribosomes along the mRNA?
Transcription factors function to help move ribosomes along the mRNA. Suppose that a portion of double-stranded DNA in the middle of a large gene is being transcribed by an RNA polymerase.
What are some examples of post-transcriptional regulation?
RNA processing, such as splicing, capping, and poly-A tail addition. Messenger RNA (mRNA) translation and lifetime in the cytosol. Protein modifications, such as addition of chemical groups.
Which of the following is an example of post-transcriptional modification?
Answer: c. The removal of introns and alternative splicing of exons is an example of post-transcriptional control of gene expression.
What are the post-transcriptional modifications required to produce mature mRNA in eukaryotic cells?
In this section, we will discuss the three processes that make up these post- transcriptional modifications: 5′ capping, addition of the poly A tail, and splicing. The 5′ capping reaction replaces the triphosphate group at the 5′ end of the RNA chain with a special nucleotide that is referred to as the 5′ cap.
What are the three post-transcriptional modifications that occur in eukaryotes?
The three post-transcriptional modifications are: 5′ capping, poly A tail addition, and splicing.
