Plz i need i will give brainliest 1.which material(s) or shapes and colors were used to represent the phosphate-sugar backbone in your model of the dna molecule?
2.which material(s) or shapes and colors were used to represent the bases in your model of the dna molecule?
3.what are the steps in dna replication?
4.what would be the complementary sequence of nucleotides for the following dna sequence: gctaattgcatccga?
5.how does the replication process ensure that new dna molecule is identical to the original (that there are no mutations)?
6.what would you need to do to make the length of your model dna molecule more accurately represent the length of a real dna molecule?

1. Phosphate= pink 2. blue

Explanation:

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
