i need help finding the right answer becasue what i wrote is wrong
Step by step
Solved in 2 steps
- The AUC and AUA codons in mRNA both specify isoleucine. What feature of the genetic code explains this? complementarity nonsense codons universality degeneracyWhich of the following statements is false? a. GTP is an energy source during various stages of translation. b. In the ribosome, peptidyl transferase catalyzes peptide bondformation between amino acids. c. When the mRNA code UAA reaches the ribosome, there isno tRNA to bind to it. d. A long polypeptide is cut off the tRNA in the A site so its Metamino acid links to the amino acid in the P site. e. Forty-two amino acids of a protein are encoded by 126nucleotides of the mRNA.How many nucleotides are in 12 mRNA codons? 12 24 36 43
- 1. What is the central dogma? What are the compounds involved in this process? (Keywords: transcription of DNA to RNA, translation of RNA to proteins; gene expression)1. Identify the name of the correct amino acid that corresponds to the correct tRNA codon and mRNA codon. State the process used to convert to mRNA and tRNA.7. Although DNA gets all the glory, it’s actually RNA that does most of the work when cells produce proteins. Explain how RNA is involved in gene expression (i.e., in transcription and translation).
- 2)Which of the following are involved in translation? Choose all that apply tRNA DNA ribosome amino acids mRNA acetyl transferase RNA polymerase rRNA1. When can a mutation on the DNA cause shortening of the translation product? Give a specific example to support your answer. 2. When can a mutation on the DNA cause production of a longer translation product? Give a specific example to support your answer.2. How many codons are there in the mRNA?
