Week 14- Chapter 21 Homework Problem 21.72 < 52 of 58 Review Constants| Periodic Table Part A How does a point mutation for an enzyme affect the order of amino acids in that protein? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help then the order of amino acids will change in the of the polypeptide chain If the resulting codon still codes for the same amino acid, If the rest of substitution of a substitution of a base in DNA changes the amino acid coded for by the codon, tRNA then the order of amino acids will differ at that point mRNA there is no effect Submit Request Answer week 14-Chapter 21 Homework Problem 21.79-Clinical Application 〈) 54 of 58 ReviewI ConstantsI Periodic Table Part A A point mutation changes a codon in the mRNA for an enzyme from GCC to GCA. Why is there no change in the amino acid order in the protein? Both codons GCC and GCA code for alanine. A point mutation does not change the amino acid order in the protein. Both codons GCC and GCA are STOP codons. Only two first base determine the amino acid order in the protein. Submit Request Answer Part A A point mutation in the mRNA for an enzyme results in the replacement of leucine with alanine in the resulting enzyme molecule. Why does this change in amino acids have little effect on the biological activity c the enzyme? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help protein function Alanine is also a and would have similar leucine. Thus, enzyme activity should be maintained because the not undergo major change amino acid of interactions to those protein structure nonpolar polar acidic polar basic function to that should Submit Request Answer Week 14- Chapter 21 Homework Problem 21.80 with feedback - Clinical Application 55 of 58 Part B A point mutation in mRNA replaces cytosine in the codon UCA with adenine. How would this substitution affect the amino acid order in the protein? Drag the terms on the left to the appropriate blanks on the right to complete the sentences Reset Help isoleucine UCA codes for codes for the protein reaches the altered codon, whereas UAA When synthesis of serine START would be observed tyrosine the same sequence cysteine STOP termination of the protein a new sequence leucine Submit Request Answer 56 of 58 Problem 21.105 ▼ Part A R.
