- Briefly describe the function of the following in protein synthesis. a. rRNA b. tRNA c. mRNAarrow_forwardA certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).arrow_forwardExplain the process of elongation during translation.arrow_forward
- Describe all the elements required to carry out the process of translation.arrow_forwardList the differences in the loading of the tRNA and its alignment with the mRNA between the initiation phase and the elongation phase of translation. (at least 5)arrow_forwardDescribe some of the ways that the initiation step of translation differs from the elongation steps of translation.arrow_forward
- Describe the role of a release factor at the end of translation.arrow_forwardIllustrate the process of translation by providing the correct bases for tRNA strand given the mRNA template strand. (Remember that mRNA has uracil instead of thymine.) Template Strand: GCUAUGUUUarrow_forwardThe initial step in the protein translation is described by: release of the initiation factors upon assembly of the initiation complex binding of mRNA to the smaller subunit of the ribosome delivery of an aminoacyl-tRNA to the A site of the ribosome formation of the aminoacyl-tRNAarrow_forward
- Describe in detail all of the steps necessary to carry out translation. You may write in complete sentences or provide a numbered or bulleted list. Be sure to indicate the role of each item below: Amino acids, mRNA, 30S ribosome, 50S ribosome, tRNA, protein chain, E site, P site, and A site.arrow_forwardConsider this list (below) of steps involved in translation. These steps are out of order. TRANSLATION: 1. the small and large ribosomal sub-units unite2. two amino acids join together.3. another tRNA anti-codon bonds with another mRNA codon 4. an initial tRNA bearing a specific amino acid arrives at the ribosome 5. the process continues until a protein molecule is completed6. at the synthesis site, initial mRNA codons are insertedarrow_forwardIndicate 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 terminationarrow_forward
