Bully whippets are homozygous for a deletion of two base pairs in the myostatin gene. The deletion changes an mRNA codon in the middle of the myostatin mRNA from UGU to UGA. Use your knowledge of the genetic code to determine the effect of this mutation on the structure of the resulting protein.

A _____________ is a point mutation that converts a codon for an amino acid to a premature stop signal.
Mutations are permanent changes in the nucleotide sequence in DNA. A point mutation is the loss or gain of a single nucleotide. If a nucleotide was lost from the DNA sequence, how would this affect subsequent transcription and translation of that gene?
According to the adaptor hypothesis, is each of the following statements true or false? A. The sequence of anticodons in tRNA directly recognizes codon sequences in mRNA, with some room for wobble. B. The amino acid attached to the tRNA directly recognizes codon sequences in mRNA. C. The amino acid attached to the tRNA affects the binding of the tRNA to a codon sequence in mRNA.
The antibiotic erythromycin works by blocking ribosomal movement (translocation) along an mRNA, in someprokaryotes. Predict the effect on protein synthesis.
During translation, small organelles called ____ read the mRNA sequence. These organelles direct transfer RNA, or tRNA, to assemble a specific sequence of ____ ____. A ____ is a sequence of three mRNA bases that codes for one amino acid.
which statement about genetic code is not true? A) mRNA is read 3 bases at a time, which are called codons. B) There is one initiator codon that codes for an amino acid. C) Each amino acid is coded for by only one codon. D) There are 3 termination codons that do not code for amino acids. E) Each codon is specific for only one amino acid. An anion has an equilibrium potential of -40 mV. What direction are the chemical and electrical forces acting on the anion at the resting membrane potential (-70 mV)?
