Document Summary
Two type of cell somatic cells gametes- zygote. The differnts in the organism is not the nda structure it"s the genes, the sequence the dna is organize. Gene is s sequence of dna, regulatory genes is special genes, they produce protein by other gene. A mutation is change in the dna, usually change in all of these errors, sometimes changes in the number of structure in the chronosomes. The protein is important everything in our body, structure, the parts in our prody, production. Note: all somatic cells have the exact same getic inflow(information). Only a small part is gene is turned on. Chromosomes are just simply structure made up of dn, only found the cell nuclei. They are only visible during replication under microscope. If you could see them during normal conditionl. Chromosome made up of 23 non- identical pair. They are not genetic the same, but the code for the same traits, but they code for different things.
