All of the following EXCEPT which one occurs between transcription and translation. -Introns are added to the RNA transcript -Exons are spliced together to form the final RNA transcript. -A modified adenine “cap” is added to the 5’ end of the RNA transcript. -All of these occur during RNA processing -A series of adenines, a “poly A tail” is added to the 3’ end of the RNA transcript.

You are studying the effect of various mutations in this gene. The AG sequence (3’splice site) that is within intron 2 [adjacent to Exon 3] has been changed to a CC.  What would the resulting mRNA transcript look like? Draw a similar diagram as above and indicate the nucleotide lengths on the mRNA transcript.

Which of the following is false? Options:   tRNAs are heavily processed but in a manner that is different than mRNAs   mRNAs are protected from degradation by modifications at the 5' and 3' end   rRNAs are all cleaved from a larger pre-rRNA precursor   Group II splicing requires protein and RNA to excise intron sequences   methylation of histone 3 at K4 results is mostly associated with activated transcription

How did they get N-Met-Ser-Gly-C?

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

Which of the following is likely associated with the mRNA processing step of alternative splicing? 1. A gene is discovered to encode for two different proteins one protein has 46 amino acids and the other protein has 86 amino acid 2. A gene has 7 exons. one processed mRNA transcript from this gene contains exons 3, 4, 6 and 7. a second process mRNA transcript from this gene contains exons 2, 3, 5, and 7 3. The open reading frame of a gene contains 90 nucleotides but the translated polypeptide contains only 29 amino acids 4. Complexity of the transcrptome ( # of different mRNA molecules) increases

Which of the following are features of transcription? -there is a direct interaction between nucleotides in the template DNA strand and incoming nucleotides being joined at the growing end of the RNA chain. -the RNA product remains permanently hydrogen-bonded to the template DNA strand. -the RNA being produced is elongated by addition of nucleotides at its 5' end. -the template DNA strand is "read" by RNA polymerase in a 3'-to-5' direction. -the site at which transcription starts is called the replication origin. More than one answer is right Please help me I’m confused

In eukaryotic transcription, which of the following is not included in the initiation of transcription? Group of answer choices RNA polymerase II TATA box Holoenzyme AAUAAA consensus sequence

The diagram, shown in attatched image, shows an mRNA that is alternatively spliced. The alternatively spliced variant contains Exon 1, Exon 2, and Exon 4. Indicate below if a splice site is used, blocked by a modifying protein such that the spliceosome must choose a different site, or skipped to make this alternatively spliced variant.
