•there are approximately 3,000,000,000 base pairs in the mammalian genome (genes constitute only a small portion of this total)• there are approximately 10,000 genes in the mammalian genome• a single gene averages about 10,000 base pairs in size. questions1. based on the assumptions above, in the mammalian genome, how many total base pairs are in all the mammalian genes? show your math! 2. what proportion (%) of the total genome does this represent? show your math! 3. what is the probability that a random mutation will occur in any given gene? show your math! 4. only 1 out of 3 mutations that occur in a gene result in a change to the protein structure. what is the probability that a random mutation will change the structure of a protein? show your math!

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
