- If an extra nucleotide is inserted in the first exon of the beta globin gene, what effect will it have on the amino acid sequence of the globin polypeptides? Will the globin most likely be fully functional, partly functional, or nonfunctional? Why?If a tRNA has an anticodon sequence 5'-CAU-3', What would be an amino acid carried by that tRNA? Phe, Val, His, or Met?Is this diagram of tRNA technically incorrect? Shouldn't it be 3' on the left and 5' on the right for the tRNA such that the 5' to 3' codon can match with the antiparallel 3' to 5' anticodon?
- How is each tRNA charged with the correct amino acid? What are the consequences of a tRNA carrying an incorrect amino acid?Which of the following is true about tRNA? Select one: A. All tRNAs have a CCA sequence at the 3'-end. B. All tRNAs have a CCG sequence at the 5'-end. C. All tRNAs have a CAC sequence at the 3'-end. D. All tRNAs have a CCA sequence at the 5'-end. E. All tRNAs have a CCG sequence at the 3'-end.An anticodon has the sequence GCG. What amino acid does this tRNA carry? What would be the effect of a mutation that changed the C of the anticodon to G?
