DNA Basics
• DNA is the most basic building block of life
• DNA makes proteins for the body
• DNA passes genes from one generation to the next
• Almost all cells have DNA
DNA to RNA
•DNA cannot leave the nuclease
•DNA splits itself and makes a copy called RNA
•The RNA is then responsible for getting the code to aRibosome which makes the needed protein
•This process is called translation and transcription
DNA in genetics
• DNA passes from one generation to the next in chromosomes
• Natural selection insures that only the most benifitial traits get passed on
• Natural selection is the reason for evolution
Natural Selection
• Natural selection starts with a random mutation which can be good or bad
• If the mutation makes it easier for the organism to survive then the trait is most likely to be passed on
• This is because the organism with the trait will be able to provide better and therefore able to mate more
