Most codons specify an _________ . a. protein c. amino acid b. polypeptide d. mRNA
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?
Given the following codons and their corresponding amino acids: UUU-Phenylalanine GAA- Glutamate CAA- Glutamine AAU- Asparagine AAC- Asn AAA- Lysine UCU- Serine GGA-Glycine ACC-Threonine AUG- Met/ START codon CCU- Proline GUU- Valine UAU-Tyrosine UAA- STOP AGG- Arginine AUU- Isoleucine CAU- Histidine GCU- Alanine UGU-Cysteir GAU-Asparti CUA-Leucine UGG-Tryptol CGU-Arginin Box 1: Show the mRNA sequence which codes for the short peptide, lys-ala-phe- leu. Include what should come before and after this short message. Don't leave any spaces between the letters. Box 2: Show the tRNA anticodon sequence that would line up with the mRNA strand from Box 1. Don't leave any spaces between the letters. Box 3 & 4: Show the DNA base sequence that would be found in the DNA double helix which carries the gene for this peptide. Give the coding strand sequence in Box 3 and template strand sequence in Box 4. Don't leave any spaces between the letters. Box 5: What if there was a frameshift at leucine…

To determine the order of bases in the first column (UNA), second column (codon) and the third column Is the anticodon. Consider the complementary base pair, in DNA and in RNA To identify the amino acid, took at the bases in the MRNA codon, example AUG using the Genetic Code Table. Loo: for the first letter of the MRNA codon on the left side of the genstis code table (A), the second letter of the MRNA on the second letter column (U), and the third letter on the right-side column (G). AUG codes for the amino acid -methionine. Do the same with the other codons in the chart. Genetic Code Table and posticn of codon Cystelne Cysteine UAU TyrY UAC Tyr Y Tyrosine USA UAG CAU His H…
From the picture provided, which colored option (exon variant) will give me: 1. start codon 2. Stop codon Im not sure how to identify with exon out of the 15 exon varients provided which one has the start codon and which has the stop I need to filter these colored options in order to find my start codon and stop codon
The sequence of a polypeptide is determined by the order of codons that specify the amino acids in the polypeptide. How many different sequences of codons can specify the polypeptide sequence methionine-histidine-lysine? (Use the table to find the number of possibilities.)

64 codons specify 20 amino acids. There are two characteristics of codons: 1. No ambiguity: Each codon specifies only one amino acid 2. Redundancy: One amino acid is specified by more than one codon Question: What advantage we get from codon redundancy?
