Document Summary
Somatic cells: all cells excluding sex cells, all somatic cells have the same genetic information. ** differences in the organisms is the sequence of genes . U instead of t; triplet code (for mrna) Regulatory genes: that produce proteins that influence other genes, send a message to the cell to be turned on (only a small part is turned on) Mutation: change in the dna, either a change in the sequence of bases or a change in the structure and number of chromosomes. Genes and mutations are important they lack the production of proteins. Proteins are important in the function of the organism (ie. they affect the regulation of system) Influence proteins that affect the organism develops from a zygote and the way they function. Normally, not during division, when they are unwrapped and lose, they are just one giant dna molecule composed of thousands of genes 3 billion base pairs.
