The information in DNA is contained in what?

Question

1. The variation in the structure of nucleotides that make up the DNA molecule

2. the type of sugars used in making the DNA molecule

3. the sequence of amino acids that make up the DNA molecule

4. the sequence of nucleotides along the length of one strand of the DNA molecule

Answer 1

1 is not your answer because the structure of all nucleotides is the same (they consist of a phosphate group, a simple sugar, and a base)

2 is not the answer because the sugar is exactly the same in every nucleotide (always deoxyribose)

3 is not your answer because DNA does not contain amino acids... those are proteins

4 is the answer because the sequencing of the nucleotides (specifically the bases) is what causes the variation of the code

Answer 2

4. the sequence of nucleotides along the length of one strand of the DNA molecule

Answer 3

4. the sequence of nucleotides along the length of one strand of the DNA molecule

They are read in sets of 3 (triplets) and each triplet has an amino acid associated with it. Amino acids can have more than one triplet that codes for it, but a triplet can only code for one amino acid.

Hope this helps :)

Answer 4

The answer is 4!

Very simply put, the information in DNA is the code for the creation of protein. As you know in protein synthesis, DNA is unwound, mRNA is copied, and the nucleotide sequence dictates how amino acids are assembled and in what sequence.

Answer 5

The answer is 4 the sequence of nucleotides (ATGC)
This leads to a the sequence of aa in a protein (not DNA)

Answer 6

None of the above, although 4 is the answer your teacher wants.

Answer 7

4 totally without a doubt

Answer 8

choice #4

Answer 9

4 is your answer

Answer 10

i believe it is 3
