In bacteria, RF2 recognizes which of the following stop codons?
Answer:
Correct choice is d- UGA/UAA
Prokaryotes have 2 codon specific factors RF1 and RF2.
RF1 for UAG/UAA and
RF2 for UGA/UAA
In bacteria, RF2 recognizes which of the following stop codons? UAG UAA and UAG UGA UAA...
I understand that there are three stop codons: UAG, UGA, UAA. Please explain why are there 6 possible reading frames (stretches that do not have any stop codons) when detecting an open reading frame (ORF) and how can cDNA help confirm the correct reading frame? Thanks!

Which of the following are typically used as stop codons in the genetic code (select all that apply)? UGA UAA UAG UGG
1. What would happen to a gene if the stop codon (UAA, UAG, or UGA) were mitated so that the first position in the codon became a “C” (CAA, CAG, CGA)? a) the protein product of the gene would be similar than normal b) either the immature RNA transcript or the mRNA will be degraded by nonsense mediated RNA decay c) its mature messenger RNA would be lengthened d) its immature RNA would be lengthened 2. Without a promoter region,...

Step 5: Determine how treatment with hydroxyamine will alter each DNA stop codon and the resulting mRNA stop codon. In the last step, the DNA equivalent of each mRNA stop codon was determined. The mRNA and matching DNA stop codons are listed in the table. Also, recall from a previous step that hydroxylamine exposure results in the replacement of a C with a T and a G with an A. Determine how the reaction of DNA with hydroxylamine will alter...
1. Which one of the following describes the NORMAL FUNCTION of a stop codon in mRNA during bacterial protein synthesis? a. It is at the end of a mRNA molecule and terminates translation once the protein is completed. b. It prematurely terminates protein synthesis resulting in an incomplete protein. c. The 3 stop codons are UGA, UAG, and UGG. 2. A tRNA with an ACC anticodon will insert the amino acid ________ during translation. (Use your codon sheet, Fig. 6...
A tryptophan tRNA gene mutates so that it recognizes one of the three possible stop codons – TGA now codes for Trp, according to the mutant tRNA. a) Will all proteins in the cell be affected by this mutation? Briefly explain your answer; if not all proteins will be affected, estimate about what fraction of proteins will be affected. b) Gene X encodes the stop with TGA. How will this mutation affect the protein X that is produced? c) Will...
