Summary Introduction
To fill: The given table that describes various aspects of eukaryotic gene expression.
Introduction: Genes are sets of nucleotides that code for a particular protein. The genes have to be expressed for the synthesis of a protein. Gene regulation is a process where the expression of genes is controlled for the synthesis of specified gene products (usually RNA or proteins). This gene expression is regulated depending on the requirement of the cell.

In tabular form and using your own words, compare and contrast the prokaryotic vs. the eukaryotic gene expression.
Indicate which of the following items are associated with transcription or translation. This could be in prokaryotes or eukaryotes, or both.
Group of answer choices: Translation OR Transcription
Sigma binds to the promoter
mRNA binds to the small ribosomal subunit

- Consider this list (below) of steps involved in translation. These steps are out of order. TRANSLATION: 1. the small and large ribosomal sub-units unite2. two amino acids join together.3. another tRNA anti-codon bonds with another mRNA codon 4. an initial tRNA bearing a specific amino acid arrives at the ribosome 5. the process continues until a protein molecule is completed6. at the synthesis site, initial mRNA codons are insertedarrow_forwardConsider this list (below) of steps involved in transcription. These steps are out of order. TRANSCRIPTION: 1. mRNA travels through a nuclear pore and enters the cytoplasm 2. the mRNA polymerase attaches at the start of a specific gene 3. RNA polymerase reads the gene surface4. a transcription factor bonds to a promoter site5. DNA molecule is unwound 6. a complimentary mRNA is produced What is the correct order of this transcription?arrow_forwardYou are working on a protein for a research project. The protein does not express well in prokaryotic expression systems so you decide to try a eukaryotic system, baker’s yeast, instead. As part of the expression system, you add a signal peptide to the protein so that it will be exported through the endomembrane system to the outside of the yeast cell. This makes purifying the protein much simpler. During the purification, you notice that the protein is heavier than it should be during gel filtration chromatography. This is confirmed by SDS-PAGE. What could be the reason that the protein has gained mass when expressed in the eukaryotic system?arrow_forward
- Consider gene expression in a prokaryotic or bacterial celI. Which of the following is true for translation or protein synthesis in this cell? Select all that apply. Small ribosomal subunit recognizes the 5' cap of the mRNA during initiation FMET charged tRNA binds to the P site during initiation The growing polypeptide is transferred from a TRNA in the P site to a charged TRNA in the A site RNA:RNA interactions are formedarrow_forwardImagine you are going to label a gene associated with apoptosis in Symbiodiniaceae with a Yellow Fluorescent Protein (YFP). To generate the YFP, you know the pre-MRNA looks as follows: Unspliced YFP premature mRNA Сap 5' UTR Exon 1 Intron Exon 2 Intron Exon 3 3' UTR Poly-A tail If Exon 2 is also required for mRNA stability, what can be predicted from the possible spliced alternative isoforms formed? One of the isoforms will not have a poly-A tail O The alternative splicing of YFP pre-MRNA prevents 5'-capping The MRNA isoform without Exon 2 will be degraded faster than the other isoform Exon 2 will be added to isoform B later to correct the mistake in splicing The protein translated from one of the mRNA isoforms will possess an additional functional domainarrow_forwardChoose any/all that apply to mRNA processing in eukaryotes. The "starter/initiator" methionine codon is added to the 5' end of each mRNA molecule during post-transcriptional processing. The entirety of every mRNA transcript is always translated to protein. The 5' m'G cap interacts with the 3' poly (A) tail (via initiation factors and other proteins) to circularize an mRNA as part of the initiation of protein translation. mRNA processing occurs while genes are actively being transcribed.arrow_forward
