When mendel crossed peas with rr and rr genotypes (where r is dominant and produces wrinkled peas and r is recessive and results
LuckyWell [14K]
I think your question all turn into lowercases, uppercases, and lowercases are important in genetics because it can differentiate between the dominant and recessive forms. 
let me explain at least how to calculate the offspring percentage:
for example, you have Rr crossed with another Rr (R for wrinkled peas and r for smooth peas), you just have to match between the four letters, and you will have four possibilities:
R and R
R and r
r and R
r and r
you will have RR, Rr, Rr, and rr
if we convert into percentages, it will give: 
25% RR
50% Rr (there's two Rr so 25 + 25)
25% rr

What is DNA, and how does it function in cells?
Tom [10]
DNA, short for deoxyribonucleic acid, is present in the nucleus of eukaryotic cells and floats around in the cytoplasm of prokaryotic cells. DNA produces blueprints which RNA carry out to ribosomes to code for protein. You can say that DNA passes genetic material through generations.

PLEASE HELP ASAPPP !!! 15 POINTS !!!
sasho [114]

***see attached pic***

Some helpful tips:

The nucleus is always going to be the big, spherical shape.

The ER is always going to be a weird, folded looking structure attached to the nucleus (rough = has ribosomes on it which are usually represented by little dots, smooth = has no ribosomes on it aka no dots)

The GA looks like the ER but it is not going to be attached to the nucleus like the ER is.

The mitochondria is always going to be pill-shaped and have weird folds inside of it.
