• Located in the cytoplasm of the cell • Respiration occurs here
1 of 9
Ribosomes
• Located in the cytoplasm • The site of photosynthesis
2 of 9
Nucleus
• Contains genes • Each gene is a section of a chromosome made of DNA • They code for a particular protein
3 of 9
DNA
• Made of 2 strands coiled to form a double helix • Each strand contains chemicals called bases • There are 4 different types of bases with cross links between the strands formed by pairs of bases • Each gene contains a different sequence of bases
4 of 9
Bases
• 4 bases = A, T, G, C • Cross links holding strands together are always between the same bases • This is complimentary base pairing
5 of 9
mRNA
Carries code needed to produce a protein from the DNA to ribosomes
6 of 9
Enzymes
• Many of the proteins that are made • Can control the activity of the cell
7 of 9
Watson & Crick
• Built model of DNA using data from other scientists • Their important discoveries = x-ray photos showed the shape of DNA as a double helix + Data indicating that the bases occured in pairs
8 of 9
Nobel Prize
• Watson & Crick received a Nobel Prize for working out the structure of DNA in 1953 and were awarded this in 1962 • Discovery needs to be checked by other scientists to make sure it is correct
