You are a scientist trying to recreate dna replication in a test tube. emplate dna moleclon nucleotides, enzymes, etc.) have been added to the test tube. the template dna molecules that you are using come from a cat, a nd the dna polymerases in use come from a dog. th e newly synthesized dna that will be produced will be most similar to
a- cats dna
b- a mixture of dog and cat dna
c- dogs dna
d- mixture of dog and cat rna

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
