GM Crops
GM stands for genetically modified. So, GM crops are plants grown for food whose genes have been altered using genetic engineering. In some cases, the genes of other organisms have been inserted into the genome of the crop plant to...

Chromosome Structure and Organization
We've all seen pictures of chromosomes, and we know that they contain DNA. But how do we get from the double helix of DNA to the X-looking shape of a chromosome? Is it just DNA, or are there other things in there? How much DNA is in each...

Animal Breeding
It explains conventional methods of animal breeding and modern biotechnological approaches, which are employed for producing high-yielding animals.

How Do Plants Reproduce?
Plant reproduction comes in two types: sexual and asexual. Sexual reproduction is similar to human reproduction, in which male pollen and female ovarian germ cells fuse into a new organism that inherits the genes of both parents. Asexual...

What Is Cancer?
What happens to cells for cancerous growths to occur? Your body is made up of millions and millions of cells. In fact there are between 50 and 75 trillion cells in the body. These cells are dying and being replaced all the time. Cancer...

Strawberry DNA Extraction
Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? DNA is the genetic instructions for how an organism develops and functions. This video will show you how to extract enough DNA from...

Nature-Nurture
Is human behaviour explained primarily by what we inherit or what we experience? This film explores this key issue by looking at the example of aggression.

Biology Cells as the Basis of Life: Cell Structure - Comparing Prokaryotic and Eukaryotic Cells
A bracelet burglar is on the loose! Sally puts on her detective hat. If she can solve the crime, maybe she’ll get a voucher to use at Tiffany & Chro. This lesson will begin our review of prokaryotic and eukaryotic cells, focusing on...

Genetics: Linkage Problem #2: Map Distance, Coefficient of Coincidence, and Interference
In this video, we explore another linkage problem in genetics in which we determine the central gene, calculate map distances, and calculate coefficient of coincidence and interference. To see our first linkage problem, click the link...

Mechanisms of Natural Selection Types of Sexual Selection
We touched upon sexual selection when we learned about natural selection. Essentially when there is a variance in the reproductive success of a particular sex for a given species, secondary sex characteristics will develop in that...

Blood groups
Imagine you’ve been involved in an accident. You’re bleeding and are rushed to the hospital. Thankfully you’re given a blood transfusion, to replace your lost blood. But you can’t just have blood from any old donor... In fact, when...

Biotechnology: Genetic Modification, Cloning, Stem Cells, and Beyond
In this biology playlist, we've learned so much about DNA and living organisms! Well, so has mankind over the past century, and oh, what we have done with this knowledge! It's pretty incredible when you stop and think about it. Let's go...

Beyond Mendelian Genetics Complex Patterns of Inheritance
We've already learned about Mendelian genetics, which taught us about dominant and recessive alleles and the laws that govern their inheritance. But things are not always so simple. There are situations that go beyond this basic...

What are Mendel and Genetic Crosses
Gregor Mendel that came up with the correct hypothesis for how inheritance of traits works. Mendel published his ideas in 1866, but it took until the 1900’s for his ideas to be recognised. Mendel studied the inheritance of different...

Apoptosis Programmed Cell Death
We've touched on apoptosis before, especially when we learned about cancer in the biochemistry series. But let's a closer look. We know that apoptosis is programmed cell death, a failsafe mechanism whereby faulty cells that pose a threat...

Mutations
So, what causes mutations? Well, this is where science fiction meets science fact, sort of. In the backstory of many superheroes there will be a meeting with a radioactive substance - be it cosmic rays or radioactive waste. In real life,...

GMOs
Genetically modified organisms, or GMOs, have had their DNA artificially modified by humans, using modern genetic manipulation techniques. By changing the DNA, so changing the genome of an organism, means we can change its...
