The genetic code is said to be triplet, meaning that there may be three ways in which an amino acid may terminate a chain. there are three amino acids per base in mRNA. there are three "nonsense" triplets. there are three bases in mRNA that code for an amino acid. none of the above Question 6 When examining the genetic code, it is apparent that there are 44 stop codons because there are only 20 amino acids. there can be more than one codon for a particular amino acid. 1 pts the code is ambiguous in that the same codon can code for two or more amino acids. there can be more than one amino acid for a particular codon. AUG is a terminating codon.

When examining the genetic code, it is apparent that there can be more than one codon for a particular amino acid. AUG is a start codon. There are 3 stop codons because there are only 20 amino acids. The code is ambiguous in that the same codon can code for two or more amino acids. There can be more than one amino acid for a particular codon.

27. When examining the genetic code, it is apparent that A. there can be more than one codon for a particular amino acid B. AUG is a terminating codon C. there can be more than one amino acid for a particular codon D. the code is ambiguous in that the same codon can code for two or more amino acids E. there are 44 stop codons because there are only 20 amino acids. 28. The relationship between a gene and a messenger RNA is that A. genes are made from mRNAs. B. all genes are made from mRNAs C. mRNAs make proteins, which then code for genes D. mRNAs are made from genes E. messenger RNA is directly responsible for making Okazaki fragments. 29. Introns are known to contain termination codons (UAA, UGA, or UAG) yet these codons do not interrupt the coding of a particular protein. Why? A. Introns are removed from mRNA before translation. B. Exons are spliced out of mRNA before translation. C. These triplets cause frameshift mutations, but not termination. D. More than one termination codon is needed to stop translation. E. UAA, UGA, and UAG are initiator codons, not termination codons. 30. In a coding experiment using repeating copolymers, the following data were obtained: Copolymer Codons produced Amino acids in polypeptide GA GAG, AGA Glu, Arg GGA GGA, GAG, AGG Gly, Glu, Arg Taking into account the wobble hypothesis and the fact that GAA codes for Glu, what are the codons for the given amino acids? A. GAG = Glu, AGA = Arg, GGA + AGG = Gly B. AGA = Arg, GGA = Gly, GAG + AGG = Glu C. GAG = Glu, GGA = Gly, AGA + AGG = Arg D. GAG = Arg, AGA = Glu, GGA + AGG = Gly E. AGA = Arg, AGG = Gly, GAG + GGA = Glu

1) genetic code a) 3 connected Nucleotides in an mRNA sequence code for amino acids - known as codons. b) 4 connected Nucleotides in an mRNA sequence code for amino acids - known as codons. c) each Nucleotides in an mRNA sequence code for amino acids - known as codons. d) code is same as binary number 0 and 1 2) Considering a triplet code, there are 64 possible codons that code for the 20 amino acids and 3 stop codons meaning that multiple codons can specify one amino acid. a) yes b) no c) that doesn't make sense d) actually 164 codons are made 3) tRNA a) Transfers amino acids, Each amino acid has a specific tRNA (20 amino acids, 20 tRNA) b) Transfer RNA, moves peptides to ribosomes c) Transfers RNA from DNA d) Transfers mRNA to cytoplasm 4) tRNA a) has an anticodon sequence of specific amino acid it attaches to on opposite side b) has no structure c) is a part of ribosomes d) in NOT synthesized from DNA
