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

O making tRNA O transcribing rRNA O removing introns from precursor mRNA O transcriptional initiation at the promoter O adding the polyA tail O mRNA binding to the small ribosomal subunit ORNA splicing O tRNA binding to codons
Place the steps below in the correct order to accurately reflect the steps by which a secretory protein is co-translationally imported into the lumen of the endoplasmic reticulum: As the polypeptide elongates and translocates into the ER, the signal peptidase cleaves the signal peptide. The SRP binds the SRP receptor, directing the ribosome to dock on the ER membrane. Termination of translation, results in the release of the polypeptide into the ER lumen, release of the ribosome from the ER membrane, and closing of the channel. The signal recognition particle (SRP) binds to the signal sequence on a newly synthesized polypeptide and stalls translation. The channel in the ER membrane opens and the polypeptide is inserted into the ER lumen. The SRP is released. A.6-4-2-3-1-5 B.4-2-5-1-3-6 C.3-1-6-2-4-5 D.1-2-3-4-5-6 E.2-6-1-5-4-3
A scientist observing a cell during gene expression would be able to easily distinguish it as a prokaryotic cell by which of the following observations? Group of answer choices as soon as the DNA introns are removed from the template after the 5' caps are converted to mRNA after a transcription initiation complex has been formed during transcription once the pre-mRNA has been converted to mRNA 2. Which of the following is least related to the other items? Group of answer choices inducer repressor operator enhancers regulator

Choose all that apply regarding gene transcription in eukaryotes: Exons are removed from mRNA by the spliceosome. RNA polymerase II must completely finish an mRNA transcript before processing can begin. RNA polymerase I catalyzes the synthesis of the majority of ribosomal RNA. Histone acetylation is a method of controlling gene expression. Acetylation creates more positive charges on histones, leading to tighter binding of the proteins to DNA. Introns must be removed from the initial RNA transcript. The hormone 17beta-estradiol binds to a G-protein coupled receptor to control gene transcription. The 5' cap of mRNA requires the free triphosphate on the nucleotide at the 5' end. Multiple transcription factors are necessary to form the pre-initiation complex (PIC) of RNA Pol II.
