Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson plan to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

DNA carries the codes for creating just the right protein. A well-designed lesson leads pupils through the process from start to finish and everywhere in between. Guiding questions with supporting video help scholars understand the...

How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

These images from Access Excellence are possible models for DNA replication. The illustrations clearly show the differences among the three ways DNA can replicate.

A good Access Excellence site with an introduction to the processes of transcription and translation, leading to a student modeling activity.
