Question

Write the mRNA that would be transcribed from following strandof DNA. DNA: GTATACCAGTCATTTGTC Suppose the bases of the DNA in the question before were nottranscribed correctly and the mRNA read: CAAAUGGUCAGUAAACAG How many mistakes were made? The protein formed is different from the one formed in thequestion before. Give one possible effect this could have inthe human body.

Explanation / Answer

Remember that mRNA would be the opposite code for DNA except thatinstead of mRNA having a T, it has a U. GTAT ACCAGTCATTT GT C   DNA CAUAUGGUCAGUAAACAG   mRNA CAAAUGGUCAGUAAACAG   incorrectmRNA, one mistake What would have been the CAU codon (codes for the His amino acid),is now the CAA codon (codes for the Gln amino acid) Incorrect sequences can cause sickle cell anemia, cystic fibrosis,tay-sachs, and phenylketonuria.
