- List all possible codons present in a ribonucleotide polymer containing U and G in random sequence. Which amino acids are encoded by this RNA?The genetic information contained in DNA consists of a linear sequence of coding units known as codons. Each codon consists of three adjacent DNA nucleotides that corresponto a single amino acid in a protien. The E.coli DNA molecule contains 4.70 x 10^6 base pairs. Determine the number of codons that can be present. Assuming that the average protein in E.coli consists of a chain of 400 amino acids, calculate the maximum number of protiens that can be coded by an E.coli DNA molecule.Codons in the set CUU, CUC, CUA, and CUG all code for the amino acid leucine. In this set, the first and second bases are identical; the identity of the third base is irrelevant. For what other sets of codons is the third base also irrelevant? For what amino acid(s) does each set code?
- The genetic code is thought to have evolved to maximize genetic stability by minimizing the effect on protein function of most substitution mutations (single-base changes). We will use the six arginine codons to test this idea. Consider all of the substitutions that could affect all of the six arginine codons.(a) How many total mutations are possible?(b) How many of these mutations are “silent,” in the sense that the mutantcodon is changed to another Arg codon?(c) How many of these mutations are conservative, in the sense that an Argcodon is changed to a functionally similar Lys codon?The amino acid glycine is encoded by four codons: GGA, GGC, GGG, and GGU. Which of the following statements correctly explains this fact? The glycine anticodon contains the sequence CC, but the 5' base of the anticodon can pair nonspecifically with the 3' base of the codon. The glycine anticodon contains the sequence CC, but the 3' base of the anticodon can pair nonspecifically with the 5' base of the codon. Glycine tRNA has four anticodons, and the appropriate anticodon specifically pairs with the correct codon. There are four tRNAs for glycine, each of which has an anticodon that specifically pairs with the correct codon. all of the aboveThe following pattern has been observed in the genetic code. For many codons, the first base specifies a biosynthetic precursor: U = pyruvate, C = α-ketoglutarate, A = oxaloacetate, G = any of a number of simple precursors. The second base of the codon tends to be associated with water solubility: water-soluble amino acids have a G, A, or C as the middle position, whereas five of seven of the most hydrophobic amino acids have U as the middle base. The third base in a codon is often information free; that is, many of the codons for the same amino acid differ only with the third base. Review amino acid biosynthesis and determine which amino acids obey these rules. What are the exceptions?
- A normal hemoglobin protein has a glutamic acid at position 6; in sickle-cell hemoglobin, this glutamic acid has been replaced by a valine. List all the possible mRNA codons that could be present for each type of hemoglobin. Can a single base change result in a change from Glu to Val in hemoglobin?DNA molecules consist of chemically linked sequences of the bases adenine, guanine, cytosine, and thymine, denoted A, G, C, and T. A sequence of three basesiscalleda codon. A base may appear more than once in a codon. a) How many different codons are there? b) The bases A and G are purines, while C and T are pyrimidines. How many codons are there whose first and third bases are purines and whose second base is a pyrimidine? c) How many codons consist of three different bases?There are different tRNAs for each amino acid. What is one major way to differentiate among the tRNAs for each amino acid?
- A series of tRNAs have the following anticodons. Consider the wobble rules listed in Table and give all possible codons with which each tRNA can pair. Q. 5′ –AAG–3′Consider the following DNA sequence, which codes for a short polypeptide: 5'-ATGGGCTTAGCGTAGGTTAGT-3' Determine the mRNA transcript of this sequence. You have to write these sequences from the 5' end to the 3' end and indicate those ends as shown in the original sequence in order to get the full mark. How many amino acids will make up this polypeptide? Determine the first four anticodons that will be used in order to translate this sequence.For the m-RNA nucleotide codons given below, what is the corresponding sequence of amino acids? AUG UGU AUA UAU GUA AUC ACC UUC UAU GUA ACA UUU UGG AAC AGC UGC CAU GUA UAC CAG AAA CUU GCA GAG CUG GCU UUG AUA UGA The α-helices are known to contain primarily the amino acids methionine, alanine, leucine, glutamate, and lysine, while β-pleated sheets are known to primarily contain the amino acids tryptophan, tyrosine, phenylalanine, isoleucine, valine, and threonine. Which one of these two types of secondary protein structure is present with this amino acid sequence?
