What 5 things are in an animal cell?

Nucleus (Contains DNA), Cell membrane (holds together and controls ins and outs), ribosome (protein synthesis), cytoplasm (chemical reactions), Mitochondria

1 of 8

What do mitochondria do and where are they commonly found?

Most of respiration takes place there. Liver cells and muscle cells

2 of 8

What 6 things are in a plant cell?

Nucleus, Cytoplasm, Chloroplasts(photosynthesis), Cell wall(support), Vacuole(cell sap), Cell membrane

3 of 8

What do bacteria cells contain?

Cytoplasm, Cell membrane, Cell wall, circular strand of dna (no nucleus), no chloroplasts/mitochondria

4 of 8

What are chromasomes made up of?

DNA - DNA divided into genes

5 of 8

What does DNA look like and what does it contain?

A double helix. Bases - AT GC (complimentary base pairing)

6 of 8

Who first modelled DNA, and how?

Watson and Crick - 1953. Used data from other scientists (X-ray showing its a double helix, bases in pairs)

7 of 8

How does DNA replicate?

Double helix unzips to form 2 single strands. New bases join on using complimentary base pairing. Result is 2 double stranded molecules of DNA
