The nucleotide sequence in DNA codes for specific codons [group of three sequential ] nucleotides which in turn code for specific amino acids which make up protiens, produced in DNA transcription the the ribosome. Genetic information allows specific protiens to be made, in accordance to what the cell needs.
I think the answer is B- nucleotide sequence, hope this helped!

B. nucleotide sequence

The key to answering this question is knowing that the sequence, or order, of nucleotides determines the order of amino acids in proteins. Proteins then perform multiple functions within the cell. More precisely, three nucleotides together comprise a codon and this codon then specifies an amino acid, according to the genetic code. See e.g., http://en.wikipedia.org/wiki/Genetic_code

B. nucleotide sequence
The nucleotide sequence is commonly represented by A, T, C, and G (adenine, cytosine, guanine, and thymine) that you see making up many representations of DNA strands. The way in whic these four units combine will determine the genetic structure of an organism. DNA is a double helix (meaning two strings together spiraled to look like a staircase). In this staircase, each step is a pair; A and T go together and C and G match up.

Peptide bonds are between amino acids that make proteins. Nucleotide sequence is the sequence that makes DNA what it is and the genes that it creates.
Nucleotides are made up of three chemicals....a phosphate, carbohydrate and base....these 3 together make up a monomer or a repeating unit that make up DNA. These monomers can be compared to the pearls on a pearl necklace....the 3 together in DNA are 1 pearl. Many pearls together make up the DNA molecule.
Hope this helps!

Juke is correct. Human DNA is made up of four nucleotides called A, C, G, and T. You can think of them as the "alphabet" of DNA - the English language has 26 letters, but the language of DNA has only 4.

We combine English letters into sequences, forming the words and sentences that we use to communicate and exchange information. In much the same way, the DNA nucleotides (A, C, G, and T) can be combined into sequences (fittingly called "nucleotide sequences") which contain GENETIC information.

As a side note, the "DNA nucleotides" are sometimes called "DNA bases".

I am not a biology expert, however by process of elimination I think I can help.

peptide bond: This is a chemical bond between two molecules (not it)

nucleotide sequences: succession of nucleotides representing the primary structure of a real or hypothetical DNA molecule (I believe this to be the answer)

triphosphates: chemical compound that is involved with RNA not DNA (not it)

uracil: Also found in RNA and is a chemical compound (not it)

Hopefully this is what you need!
