5.3 DNA and genes
Slide 1 - Diapositive
Slide 2 - Vidéo
DNA
Slide 3 - Diapositive
DO YOU REMEMBER?
Slide 4 - Diapositive
nucleotides (base of DNA)
Slide 5 - Diapositive
4 different bases (nucleotides)
c
ytosine
g
uanine
a
denine
t
hymine
Slide 6 - Diapositive
Slide 7 - Diapositive
double helix (ladder)
Slide 8 - Diapositive
information is stored in code
AATCCGGACGAATTCCGGAAAAAATTTTTTTTTTTTTTTTTTCGCGCGAATTCATATATATCGGACGGACGAAC etc etc etc it would be a very thick book :-)
Slide 9 - Diapositive
GENE: section of DNA with complete code for a protein
Slide 10 - Diapositive
proteins
Lots of functions
E.g. enzymes, hormones, antibodies, cell structure
gene = code for 1 protein
Genes determine your characteristics
Slide 11 - Diapositive
copying
you start with one fertilised egg with 46 chromosomes...
you end up with billions of cells with the same 46 chromosomes => all of them a copy from the original.....
things can go wrong on the way => mutations (5.5)
Slide 12 - Diapositive
from DNA code to proteins
3 bases = 1 amino acid
ACC is code for one type
AAG is code for another
21 different amino acids.
string of amino acids = protein
Slide 13 - Diapositive
amino acids -> protein
