For this biology worksheet, 9th graders identify and explain what cell stay in inter-phase. Then they describe which stage of cell is the shortest and determine why that is true. Students also explain the process of mitosis.

You can use these slides to explain the many complicated steps of the Polymerase Chain Reaction. The diagnostic and forensic uses of gel electrophoresis are detailed. This PowerPoint could be used to communicate facts, or to prompt...

Advanced biology masters take a close look at DNA and the scientists who contributed to our understanding of this complex and powerful molecule. They answer 21 questions about DNA structure, replication, and repair. This can be used as a...

A continuous cascade of information comes through this PowerPoint on biotechnology. The topic is defined, a history is presented, and basic genetic engineering techniques are explained. The topic is covered in an objective manner,...

Students explore DNA, genes, chromosomes and the chemicals that make up DNA. They research Internet resources to develop their knowledge of DNA. They conduct an experiment to separate DNA from peas and create a poster that they can use...

Are you a mutant? Learn about multiple types of mutations with a presentation to discover the answer. Both genes and chromosomes mutate at various points in their life cycles. Slides describe each type and the resulting impact on...

In this science worksheet, students study the relationships between cells, DNA, chromosomes, bases and genes. Students cut apart 6 cards and paste them onto another paper in order from largest objects to smallest objects. Prior knowledge...

Young scholars explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using...

Students define attributes of human chromosomes and match them to make a human karyotype.  In this investigative lesson students demonstrate how traits are encoded in genes found on chromosomes. 

Teenaged scientists can use this quiz or study guide to show off their understanding of genetic mutations and their causes; includes short answer, multiple choice, matching, and more.

Students draw a picture of a person from popular culture, then "clone" it using printing techniques in this Art lesson that tackles the questions surrounding cloning, DNA, and current scientific techniques. An emphasis is placed on the...

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...

In this DNA instructional activity, students identify the different parts of the DNA and color them. They complete 16 short answer and fill in the blank questions on DNA.

In this DNA replication worksheet, students review the steps that take place for DNA replication. This worksheet has 9 fill in the blank questions.

Young scholars examine inheritance of blood types.  In the chromosome lesson, students create a model of chromosome and predict the blood type of offspring.

Students engage in a lesson that is concerned with the "X" chromosome and how ti is part of genetics with the use of Punnett squares. They use this tool in order to predict future genetic outcomes while focusing upon specific questions.

Students read about the X and Y chromosomes in humans and complete a worksheet.

Introduce the concept of genetics to your kindergartners with a science experiment about chromosomes in fish. After a quick overview of what chromosomes are, learners color different chromosomes to show that they come from the mom or the...

Students interact with a video to explore the basis for the science of chromosomes. They perform a chromosomal analysis called a karyotype and explore how seemingly minute errors in chromosomes can lead to devastating illnesses.

Students use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs. environmental...

Students examine the difference between mitosis and meiosis, and describe the steps involved in meiosis and the significance of each step. They create a diploid nucleus containing two pairs of chromosomes using clay.

In this genetic change learning exercise, students will explore the changes that can occur in DNA including point mutations and chromosomal mutations. This learning exercise has 11 multiple choice questions.

In this biology word search worksheet, students search for 29 words that are located in a word bank at the bottom of the page. They find words such as chromosomes, alleles, DNA, and populations.

Students study genetic traits using popsicle sticks as chromosomes. For this biology lesson, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.
