Students experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.

Students explore the "genetic code." They observe how genes may be manipulated for genetic research, gene cloning, and genetic engineering. In a lab setting, students examine the mechanics involved in cutting and ligating DNAs into a...

The metaphors used here to describe the "cut and paste" procedures for genetic engineering will really help your biologists in their understanding of restriction enzymes and DNA.  The uses of genes that are isolated and incorporated...

After studying DNA replication and the genetics of inheritance, this slide show is useful for explaining specific mutations that can happen and result in an illness. Sickle cell anemia, and cystic fibrosis are explained on a genetic...

The basics of mutation types and some potential effects of those are described and diagrammed here. Each detail is very clear and includes the labels and translation change exhibited. A great slideshow to expand on DNA replication issues.

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Learners explore enzymes and enzyme combinations. They examine and cut up and practice matching DNA sequences.

In this nutrient biochemistry worksheet, students complete the blanks with information about nucleic acids and the process. Students also draw a figure referenced in the text given.

Students experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.

Young scholars are able to explain their models to other students and to their parents. Then young scholars like to decorate the room by hanging the models or constructing mobiles of a number of models.

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Students, working in teams, assume they are the newly hired research director of a biotech firm interviewing the top two candidates for the position of research scientist. They evaluate the candidates and decide who should be hired based...

Students identify chromosome pairs based upon band patterns and location of centromere. They order chromosome pairs based upon size. Students differentiate normal karyotypes from abnormal karyotypes. They correctly record karyotype...

In this replication worksheet, students color in the nucleotide outline and the enzymes plus the base pairs to show the replication of DNA.

Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...

For this adaptations worksheet, learners read about 3 species that have changed over time to adapt to their environment. Students design a squirrel that has adapted to an island habitat that learners are assigned. They describe the...

In this organic chemistry learning exercise, students solve 20 problems including isomer structure, functional groups, types of reactions and the polymers that make up the structures of organic molecules.

Students conduct Internet research on Antisense Oligonucleotide Therapy. They design a puzzle to represent these processes, read and summarize an article, conduct research, and design a theoretical experimental procedure.

Students identify the steps in a gel electrophoresis experiment and describe the role of enzymes. They examine the relationship between fragment size and migration rate in a gel. They view DNA fragments as well.

Pupils explain the importance and function of enzymes. They compare and contrast the processes of DNA replication and polymerase chain reactions. They practice using new vocabulary as well.

In this biology worksheet, students identify and describe the three types of RNA, messenger, transfer, and ribosomal RNA. Then they write the key features of molecules of RNA for each form.

Learners explore neurological disorders. They examine the presence and absence of discernible genes. Students describe neruological diseases and draw faces of affected persons. They play a human neurology disorders learning game.

Students see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They comprehend how blood corpuscles manufacture normal hemoglobin. Students already comprehend that genes control the synthesis...

Ninth graders determine nucleotide sequences. They identify those base sequences that are normal, those that are normal variants and those that cause cystic fibrosis. Students use DNA nucleotide sequences to determine amino acid...
