Topics so far included in pdf bundle:

Coronavirus life cycle:
Two levels of detail, the first shows how the virus replicates within host cells, highlighting how the human cell’s own machinery is doing all the work and providing the materials. https://youtu.be/SlAIc_uE3cwThe
The second goes into more detail of the molecular biology, but still at a fairly basic level.

Antigens: This simply shows the the two main categories of antigen; those recognised by antibodies and those recognised by T cells.

Antibodies: How they are produced by B cells, how many we have at birth, what happens during an antibody response, what other cells do when a pathogen has been coated with antibodies.

Vaccines: the challenge of virus mutation https://youtu.be/9TEeBiwwkNI

The function of helper and Killer T cells: https://youtu.be/JKPrvaqssRk

Photosynthesis: The first sheet shows why water is used and oxygen is produced
https://youtu.be/aNw0QnZI0GU

The second is on the Calvin cycle and shows how carbon dioxide is incorporated into sugar.

Mitosis: A summary of how nuclei divide
https://youtu.be/jZ58O72SXYI

Meiosis: Highlighting the point at which crossing over and recombination occur
https://youtu.be/lo7VwUCBSuY

DNA replication: The role of DNA polymerase in DNA replication. This works as background information for understanding PCR
https://youtu.be/HWP84mDZMH0

The structure of DNA and RNA: There is only a very slight difference between these two molecules. I made this one because coronavirus contains RNA as its genetic information.
