1. the double helix structure of the dna looks like a ladder. which parts create the rungs? which parts hold the rungs together?

2. what components make up a nucleotide?

3. which nitrogenous bases pair with each other? what type of hydrogen bond forms between them?

4. what is the relationship between chromosomes, genes and dna molecules?

I'm not sure about 4. sorry, but

Explanation:

1. The hydrogen bases are like the rungs, and the base pairs make up the part that holds the rungs

2. The phosphate, the deoxyribose sugar, and the base

3. C pairs with G, and A pairs with T,

C - G

A - T

im not in connections yet but i might can you some questions. what grade are you in?

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
