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
