Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

In this protein synthesis worksheet, students use a given strand of DNA to write the complimentary base pairs. They transcribe the message to the RNA and then they translate the message into the proper amino acids using the codons on the...

In this chromosome activity students complete a crossword puzzle by answering questions on DNA, nucleic acids, nucleotides and RNA.  

Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs,...

In this how HIV infects cells activity, students read the given information about how HIV infects cells. Students explain the role of various structures in HIV infection. Students design a drug that might slow the rate of cellular...

Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

Most pupils know about the flu, HIV, and other viruses, but they don't know what each actually looks like. This interactive shows their relative size, structure, and allows for comparisons. It stresses the similarities and differences...

Provides the three models of replication and shows how they would create different DNA strands. Good graphics and explanations.

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.

Observe the animated model to see DNA being replicated.
