A polyA tail makes the mRNA makes degrade more quickly.

Select the features of a eukaryotic mRNA that are not encoded in the genome. Select all that apply. O Intron O Exon 5' Cap O Poly A tail Promoter O start codon

The complement to a coding strand has the sequence 5' - TACTTTAGGATC - 3'. What is the MRNA strand for this sequence?

Failure to add the 3’ polyA tail will result in which of the following? The prokaryotic mRNA cannot be translated A break in the 5’-5’ triphosphate bond The eukaryotic mRNA is not transported outside the nucleus No changes, the polyA tail is not necessary

How can one primary transcript result in several polypeptides with different amino acid sequences? alternative splicing of exons O phosphorylation of proteins after translation incorporation of an amino acid at a stop codon addition of a polyA tail to the mRNA

Proteins can be made from a mRNA transcript before transcription is completed in prokaryotes because (choose the best answer): They have pol d and pol e They do not need to export the transcript out of a nucleus They add a 5' cap to the transcript They have a Shine-Delgarno sequence

Which of the following would not be found in a mature mRNA in a eukaryotic cell? A Star Codon B Poly-A tail C Promoter D Exons
