Decoding DNA

Course Access: Lifetime
Course Overview

Become familiar with the structure of DNA and how it codes for proteins.  Before participating in DNA Detective or DNA Barcoding on-site programs at Ecolinc, it would be advantageous if students completed this pre-learning program to ensure their understanding of DNA structure and function. The course involves a detailed look at how nucleotides make up the DNA molecule. It also allows students to ensure they are familiar with the sequence of events during protein synthesis and have an understanding of the terms they will be using during the on-site visit.

Background information

DNA is the molecule of life. This double helix structure contains all the information necessary to build and maintain an organism. However, DNA does more than specify the structure and function of living things — it also serves as the primary unit of heredity in organisms of all types. In other words, whenever organisms reproduce, a portion of their DNA is passed along to their offspring. But what, exactly, is DNA? What smaller elements make up this complex molecule, how are these elements arranged, and how is information extracted from them? This course answers each of these questions.

Year Level: Yr 11

Prior knowledge

It would be expected that the students would have some prior knowledge of cells and organelles.

Course Connections

Does this course link to other Ecolinc programs?

This course is an ideal introduction to the following on-site programs:

Be A DNA Detective
How inheritance is explained: DNA Bar Coding

or this course can stand alone as a learning experience.

Learning intentions

  1. Label a diagram of DNA showing the different parts that make up this molecule as well as showing specific pairing between nitrogen bases
  2. Sequence the events that occur during protein synthesis
  3. Match the glossary words with their meetings

Estimated Duration: 60 minutes

Victorian Curriculum

  • Science Understanding (Year 9 & 10)

The transmission of heritable characteristics from one generation to the next involves DNA and genes(VCSSU119)

VCE Area of Study

Biology Unit 2 AoS:

    • The distinction between a genome, gene and allele
    • The genome as the sum total of an organism’s DNA measured in the number of base pairs contained in a haploid set of chromosomes
    • The role of genomic research since the Human Genome Project, with reference to the sequencing of the genes of many organisms, comparing relatedness between species, determining gene function and genomic applications for the early detection and diagnosis of human diseases.

Outcome Descriptor:

On completion of this unit the student should be able to apply an understanding of genetics to describe patterns of inheritance, analyse pedigree charts, predict outcomes of genetic crosses and identify the implications of the uses of genetic screening and decision making related to inheritance.
