Explain briefly HOW we have different cell types (blood, skin, muscles, nerves, etc.) *

Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
