The most common type of termination signal in E. Coli is a symmetrical inverted repeat of GC rich sequences followed by about 7 As that forms a stable stem-loop structure in the RNA, which disrupts its association with the DNA template and terminates transcription. true or false

For each of the following initiation factors, how would eukaryotic initiation of translation be affected if it were missing? A. eIF 2 B. eIF4 C. eIF5

Explain the difference between prokaryotic and eukaryotic transcription. In 3-4 sentence

Describe the initiation step of bacterial transcription (make sure to include important enzymes, parts, and sequences in your answer) up to the beginning of elongation. What are three ways that transcription differs between bacteria and eukaryotes? (I'm not looking for types of RNA modification, just in terms of transcription)

Which of the following sequences would most likely be the site of the initiation of transcription? ТАТАААТА GCTAGCTA GGCGGCCC Impossible to tell

A string of 8 adenine nucleotides in the mRNA is required for function of an intrinsic transcription terminator in bacteria. True False

Although the genetic code is universal, a few organisms such as Paramecium have a slightly modified version in which UGA, a stop codon for most organisms, codes for tryptophan in Paramecium. Suppose that the researcher wanted to make an in vitro translation system using all of the components from Paramecium. Which of the components, if any, would she need to replace in order to have an in vitro system that was universal? Possible Answers: A. She would need to leave out the P site. B. She would need to leave out the termination factor proteins. C. She would need to leave out the tRNA that recognizes UGA. D. She would need to leave out the ubiquitin

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
