This is a list of molecular changes that could happen during DNA replication, transcription, mRNA processing, or translation. For each, determine whether or not the change will be passed down through generations of cells after it occurs. Explain your answer.  C->G point mutation in the DNA of a coding region of a gene A->T point mutation in the noncoding region of a gene An error in transcription changes the mRNA sequence such that what was an amino acid-coding codon in the DNA sequence is now a stop codon in the mRNA sequence. An error in translation causes the amino acid alanine (nonpolar) to be replaced by the amino acid glutamic acid (polar and negatively charged).

Question

 This is a list of molecular changes that could happen during DNA replication, transcription, mRNA processing, or translation. For each, determine whether or not the change will be passed down through generations of cells after it occurs. Explain your answer.

  •  C->G point mutation in the DNA of a coding region of a gene
  • A->T point mutation in the noncoding region of a gene
  • An error in transcription changes the mRNA sequence such that what was an amino acid-coding codon in the DNA sequence is now a stop codon in the mRNA sequence.
  • An error in translation causes the amino acid alanine (nonpolar) to be replaced by the amino acid glutamic acid (polar and negatively charged).
