Determine what amino acid will be formed from the given DNA strand below:
3’ T A C A T G C C G A A T 5’
Note: Prepare the partner strand of this DNA. Discuss how will replication happen by mentioning the enzyme needed then transcribe to form mRNA. Discuss what will happen to mRNA, then translate, mentioning the anticodon to be used. Look at the genetic code to know what amino acid will become part of the polypeptide chain.
1. Partner DNA strand
2. the mRNA strand
3. the tRNA
4. the formed amino acids
Describe the function of DNA polymerase. Explain why each part of the name DNA polymerase (DNA, polymer, -ase) makes sense.
Illustrate the major features of DNA’s primary and secondary structure. Explain the concept of polarity as it applies to the structure of DNA.
