Poll

How did humans first become infected with Covid-19?

Another human had it first

It came from an animal

It came from outer space

A human created it

3

Poll

Which animal did the Covid-19 virus come from?

4

Bats

  • Bats are known carriers of the coronavirus.

  • In 2003 there was another coronavirus threat linked to bats

  • Bats tested in the first Covid-19 hotspot have a similar viral genome to the virus found in humans

Multiple Choice

How do we know that this virus came from bats?

1

humans and bats have similar DNA

2

They found a sick bat with Covid

3

The viral genetics

4

We don't know

The Genetics of Covid-19

  • Covid-19 is an RNA strand virus

  • These strands of RNA have a genetic code that tells a host cell how to build more of it.

  • The RNA is the instruction manual

  • The viral covid RNA found in bats is very similar to the viral covid RNA found in humans

What is RNA?

Ribonucleic acid

  • RNA is a strand of genetic information made from nucleotides

  • Nucleotides are the structural parts of RNA and DNA

Multiple Choice

What are the structural parts of RNA and DNA called?

1

Ribosomes

2

Nucleotides

Ribonucleic Acid

Nucleotides

  • Nucleotides are found in both RNA and DNA.

  • There are 4 nucleotides that make RNA (Adenine, Guanine, Cytosine, Uricil)

13

Groups of Nucleotides

  • Three nucleotides next to each other make up a "Codon"

  • Codons code for amino acids (protein)

  • Proteins code for EVERYTHING in the cell (genetic traits, hormones, enzymes)

Multiple Choice

A group of three nucleotides next to each other make up a...

1

Codon

2

RNA strand

3

nucleic acid

4

Base pair

Recap:

  • Covid-19 is a RNA strand virus which means all of virus's genetic information is one strand of RNA

  • RNA is a single strand of genetic information that tells the cell what proteins to make

  • The cell looks at 3 nucleotides next to each other that code for amino acids

  • The amino acids will then make proteins or more virus
