The causes of genetic mutations (video) | Khan Academy
Explore the causes of genetic mutations, diving into the world of point and frame-shift mutations. Understand how base substitutions, like transitions and transversions, lead to point mutations. Discover how insertions and deletions can cause frame-shift mutations. Finally, get a glimpse of large-scale mutations, such as translocation and ...
Genes & Mutations Video For Kids | 6th, 7th & 8th Grade Science
Mutations are a change in the genetic code, DNA, and can sometimes lead to proteins being made wrong. An example could be a mouse that inherited a gene with a mutation, so it didn’t grow any hair. Give an example of a mutation and explain if the mutation is good, bad, or doesn’t change the organism.

Mutagens and carcinogens (video) | Mutations | Khan Academy
Mutagens and carcinogens can cause DNA damage, affecting protein production. Mutagens, either endogenous or exogenous, increase genetic mutation probability. Endogenous mutagens, like reactive oxygen species (ROS), are produced by the body. Exogenous mutagens include intercalators and base analogs.
Lesson Video: Genetic and Chromosomal Mutations | Nagwa
In this video, we will learn about changes in DNA that we call mutations. We will see how these mutations can affect the information that DNA carries and learn how to identify the different types of mutations on both genes and chromosomes. We’ll also learn more about spontaneous mutations and induced mutations.
DNA Damage and Mutations - BioInteractive
2003年2月5日 · This animation shows how mutations can arise when DNA is damaged. DNA can be damaged by radiation and reactive molecules, such as free radicals. As discussed in the animation, this damage may create mutations by chemically changing the DNA. Most mutations are corrected by DNA repair processes in the cell.
A Mutation Story - PBS LearningMedia
This video segment tells the story of a genetic mutation affecting the human population of West Africa. Although helpful in preventing malaria, this mutation can also lead to sickle cell anemia. Sickle cell specialist Dr. Ronald Nagel stresses the genetic diversity required for …
