DNA Structure & Replication
Protein Synthesis
Learning Outcomes that will be tested...
B4 - Analyse the structure and function of nucleic acids in biological systems
- List the major functions of RNA and DNA
- name the four nitrogenous bases in RNA and describe the structure of RNA
- name the four nitrogenous bases in DNA and describe the structure of DNA
- Compare DNA and RNA
B5 - Describe DNA replication
- describe the three steps in the semi-conservative replication of DNA: unzipping, complementary base pairing, joining of adjacent nucleotides
- describe the purpose of DNA replication
- Identify the site of DNA replication
B6 - Describe recombinant DNA and describe a minimum of three uses for recombinant DNA
B7 - Demonstrate an understanding of the process of protein synthesis
- Identify the roles of DNA, mRNA, tRNA and ribosomes in transcription and translation
- determine the sequence of amino acids coded for by a DNA sequence given a mRNA table
- identify the complimentary nature of the mRNA and the tRNA anti-codon
B8 - explain how mutations in DNA affect protein synthesis
- give examples of environmental mutagens
- use examples to explain how mutations in DNA change the sequence of amino acids in a polypeptide chain and as a result may lead to genetic disorders
