DNA is made up of two strands. Each strand has one of four bases on it. These are adenine, thymine, guanine and cytosine. On the other strand will be a matching pair. Adenine will match up with thymine and guanine will match up with cytosine. To make it easier, we just say A matches with T and G matches with C. On RNA "T" or thymine is replaced by uracil "U". In this case everything remains the same except now U matches up with A.

What two things make up a chromosome?
Chromosomes are comprised of nucleotides and nitrogen base pairs. The nucleotides make up the columns of the DNA structure, and are repeating sequences of a 5-carbon sugar and a phosphate. The "rungs" of the DNA structure, similar to the rungs (steps) of a ladder, and made up of four variations of nitrogen base pairs.
How are the 2 nucleotide strands connected?
In drawings of DNA the lines connecting the two strands represent base pairings. DNA is made up of four base pairs. These four pair up A-T and C-G exclusively.
A molecule of DNA is made up of?
Atoms. Water molecule is made up of two hydrogen and one oxygen atoms. Carbon di oxide is made of one carbon and two oxygen atoms. Methane is made up of one carbon and four hydrogen atoms. Even oxygen gas molecule is made up of two oxygen atoms.
DNA is described as a zipper or corkscrew unwound it looks like a ladder of what substances are rails and rungs composed?
The rails of DNA are made up of pairs of sugars and phosphates. The middle of the strand of DNA or the rungs are made of nucleotides and bases of codons, such as ATCG base pairs. The bond that holds the DNA together is a hydrogen bond.
The unit of a DNA molecule which is made up of a nitrogen carrying base a sugar molecule and a phosphate group is called a what?
DNA and RNA are nucleic acids. When broken to the smallest unit it is called a nucleotide. The nucleotide of both DNA and RNA is up of a sugar molecule which is attached to a phosphate group and a base. The bases of DNA are thymine, adenine, guanine, and cytosine. In RNA adenine is replace with uracil while it keeps thymine, guanine, and cytosine. In DNA adenine pairs with thymine, and cytosine pairs with guanine. In RNA uracil pairs with thymine, and cytosine pairs with guanine.
One DNA molecule in a single human cell is made up of about billion base pairs?
two
What is a molecule that appears on pairs of a DNA strand?
Something that would appear in pairs on a DNA strand would be a base. The bases are made up of different parts: A:Adenine C:Cytosine G:Guarnine T:Thymine
What makes up the inside ladder part of the DNA?
The Base Pairs

What base does guanine pair whit?
Guanine pairs up with cytosine in both DNA and RNA while adenine pairs up with thymine in DNA only.
What is DNA in your body?
DNA (deoxyribonucleic acid) is a molecule made up of an elaborate arrangement of the base pairs adenine, thymine, guanine, and cytosine. Each specific arrangement of these base pairs in the molecule account for every trait that a living being possesses. More simply, DNA is the blueprint for life.

Why can you predict the base of one strand in a molecule of DNA if you know the sequence of the other strands?
in DNA, each base pairs up with only one other base
How many base pairs make up a codon?
One codon is made up of three base pairs.
Why can you predict the base sequence of one strand in a molecule of DNA if you know the sequence of the others strand?
in DNA, each base pairs up with only one other base
