DNA
These are the standards you must teach with your Website:
SC.912.L.15.15: Describe how mutation and genetic recombination increase genetic variation.
SC.912.L.16.3: Describe the basic process of DNA replication and how it relates to the transmission and conservation of the genetic information.
SC.912.L.16.5: Explain the basic processes of transcription and translation, and how they result in the expression of genes.
SC.912.L.16.9: Explain how and why the genetic code is universal and is common to almost all organisms.

Also have these on your website
You can focus your presentation on these (just briefly explain the above standards):
-How DNA is used in Forensics. (paternity, genetic markers, crime scene investigations, forensic chemistry).
-What does DNA look like? Include pictures and diagrams.
-What does DNA do?
-What is a double helix?
-Why is the study of DNA important?
-How has the study of DNA evolved over time?

Tip: Watch video clips about each of the standards to help aid in your understanding.
