What else can I help you with?
What part of DNA is found at the centre of the molecule?
phosphate molecule
What part of DNA gives the molecule a negative charge?
The phosphate groups in the DNA molecule give it a negative charge.
Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
What part of the nucleotide make up the backbone of the DNA molecule?
dna strands
Are phosphate groups part of a DNA molecule?
Yes
What molecule carries genetic information?
Chromosomes do that part.
Three thing make the structure of a DNA molecule?
The structure of a DNA molecule is made up of three things: a sugar-phosphate backbone, nucleotide bases (adenine, thymine, cytosine, and guanine), and hydrogen bonds that form between the bases. These components form the double helix shape of the DNA molecule.
Are nucleotides pieces that form the dna molecule?
Yes, nucleotides are the building blocks of DNA. They are composed of a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine). These nucleotides link together to form the double helix structure of the DNA molecule.
Are the phosphate groups on the interior or exterior of the DNA molecule?
On the exterior linking the sugar backbones together.
What sugar is a componenet part of a DNA nucleotide?
The sugar deoxyribose is a component of a DNA nucleotide.
Which pair of nitrogen bases will form a bond in a DNA molecule?
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
What is DNA, a complex molecule with a double helix shape?
DNA, or deoxyribonucleic acid, is a complex molecule that carries genetic information in the form of a double helix structure.
