Which of the following statements describes the function of the sigma factor in prokaryotic transcription? It catalyzes the removal of the introns to produce mature mRNA to terminate transcription. It causes the RNA polymerase to detach from the mRNA to terminate transcription. It catalyzes the synthesis of mRNA in a 5' to 3' direction to implement transcription elongation. It attaches the amino acid to its cognate tRNA to initiate translation. It facilitates the binding of RNA polymerase to the promoter to initiate transcription.

Put the following processes in order of their occurrence during expression of a eukaryotic gene: a. mRNA processing c. transcription b. translation d. RNA leaves nucleus
Identify whether each of the following descriptions applies to typical prokaryotic genomes only, typical eukaryotic genomes only, both, or neither, according to lecture. Answer options may be used more than once or not at all. Composed of double-stranded DNA only. Each chromosome has a centromere. Species with larger genomes have more genes. [Choose ] [Choose ] prokaryotes only neither eukaryotes or prokaryotes eukaryotes only both prokaryotes and eukaryotes [Choose ]
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 Spliceosomes remove introns and splice together exons Nucleotides are added from the 5' to 3' end tRNA anticodon binds to the corresponding mRNA codon STOP codon results in termination
Which step in the processing of heterogeneous nuclear RNA (in eukaryotes), into mature messenger RNA, is required for proper attachment of the small ribosomal subunit to the mature mRNA molecule? polyadenylation at the 3’ end 7-methyl-guanosine capping at the 5’ end excision of introns formation of quadruple-stranded DNA splicing of exons
Which of the following is true of the timing of RNA processing? The premise is false; mRNA processing does not occur in eukaryotes mRNA processing occurs in the cytosol after pre-mRNA is exported from the nucleus mRNA processing occurs co-transcriptionally mRNA processing occurs in the nucleus after transcription has terminated
Which of the following statements about translation is false? In eukaryotes, the 5' cap and the 3' poly(A) tail are involved in translation initiation. Peptidyl-transferase activity during translation is the property of a ribozyme. A base at the first position of an anticodon on the tRNA would pair with a base at the third position of the mRNA. The growing peptide chain is transferred from the tRNA in the P site to the tRNA in the A site. Ribosomes move along an mRNA in the 3’ → 5' direction.
Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. It is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. What is the difference between Rho Dependent and Rho Independent termination in prokaryotes?
Which of the following cannot be said regarding aminoacyl tRNA synthetase? It is essential for the correct reading of codons. A single tRNA synthetase can attach different amino acids to their corresponding tRNA. It is first activated when it catalyzes a reaction between ATP and an amino acid to form an aminoacyladenylic acid (amino acyl-AMP). It is responsible for the attachment of the correct amino acid to the correct tRNA. There is a different tRNA synthetase for each amino acid that will be attached to a tRNA.
Transcription and translation are separate processes in gene expression; however, they have similarties. The following terms all relate to translation. Which of these has a role that is most similar to that of the transcription start sit during transcription ? A- Start Codon B- Stop Codon C- tRNA D- Amino Acid
Which of these statements is true about the elongation step of translation? The growing polypeptide chain is transferred from the P site RNA to the A site RNA The MRNA moves through the ribosome The new amino acid is transferred from the A site RNA to the growing polypeptide chain in the P site The small ribosomal subunit detaches and reattaches every time a new amino acid is incorporated into the growing polypeptide
Which of the following processing events occur during or after the synthesls of MRNA molecules in eukaryotes? Intron splicing Addition of a 5'cap O Cleavage of multiple functional molecules from a larger precursor O Polyadenylation of the 3' end
In which order do the following events occur in prokaryotic transcription (from 1 = first to 4 = last)? The new RNA strand detaches from the DNA template and RNA polymerase RNA is synthesized in the 5' to 3' direction RNA polymerase reaches the termination site RNA polymerase complex binds to the promoter
