Chromosomes

Mutations are not just deformed creatures we see in movies—they happen every day! Scholars study the different types of genetic mutations in the 12th installment of a series of 18 lessons. A creative activity uses candy and other food...

Young scientists demonstrate their creativity while completing several activities, to assess genetic variations and mutations. Instructors provide a list of options and scientists choose to write a comic strip, create a book,...

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...

Are the only mutants you know Ninja Turtles or X-Men? The video explains both gene mutation and chromosome mutation. It includes the subtypes of mutations for each major type, the times when mutations are more likely to happen, and...

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

Students come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students examine a fictional pedigree and determine which gene is responsible for a given trait. The...

Forward and backward, it's all the same! Scientists recently discovered the y chromosome's palindrome nature suggests it's possible to for the y chromosome to recombine with itself! An animation resource gives viewers insight into the...

No, you didn't get your genes from the local clothing store. Learn where they really come from by watching this video as it explores how the genes found in all plants and animals today have arisen over...

An informative video begins by showing scholars how chromosomes are like encyclopedias. The instructor then explains and differentiates genome, chromosome, sister chromatids, nucleosomes, DNA, genes, and base pairs. 

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...
