A codon is: three amino acids on a polypetide that are snipped off by the helicase enzy O sets of nucleotides on the tRNA, opposite the anti-codon sequence an MRNA component that specifies a specific amino acid that which attaches to the mRNA triplet sequence a don that goes with another don the protein that begins transcription by breaking H bonds

Which one of the following is a codon for amino acid valine RNA triplet code GUU? AGT CAA GUC UGA ACC

Which of the following is responsible for creating the covalent bonds that link the amino acids of a protein in the order specified by the gene that encodes that protein?    rRNA tRNA mRNA ribosome

Which one of the following options is NOT a step in RNA processing? Addition of the 5’ G cap Addition of the 3’ poly A tail Splicing to remove exons and connect the retained introns Splicing to remove introns and connect the retained exons

Which one of the following features could you use to determine the length of the RNA that is produced based on the gene, before it is processed? The exon and intron sequences The promoter and enhancer sequences The start and stop codons for translation The transcription start and termination sequences

The genetic code is Random in that the codons for the same amino acid are structurally unrelated Read by pairing codons in TRNAS with anticodons in mRNAs Read by pairing anticodons in TRNAS with codons in MRNAS Redundant in that each codon can code for multiple amino acids

N   Transfer RNAs (tRNAs) serve as adaptors between mRNA and amino acids during protein synthesis. Determining right and wrong

An anti-codon is the sequence of the nitrogenous bases on the?  complementary strand of DNA which codes for one amino acid complementary strand mRNA which codes for one amino acid tRNA molecule where the amino acid is attached tRNA molecule which recognises the appropriate sequence of bases on the mRNA mRNA molecule which instructs the ribosomes to initiate protein synthesis

Which of the following would not be found in a mature mRNA in a eukaryotic cell? A Star Codon B Poly-A tail C Promoter D Exons
