How many strands of nucleotides are in a DNA molecule?
There are two strands of DNA in a DNA double helix, each consisting of many nucleotide subunits. They are like building blocks that make up the DNA molecule, which would then be like a block tower. A 'strand of nucleotides' as you put it would basically be a DNA molecule (if they are deoxyribose nucleotides) or if they are ribose nucleotides, they would be a RNA molecule. DNA can come in double stranded helices (most of the time) or can be single stranded (as in some viruses).
How many stands make up DNA double helix?
A DNA double helix is made up of two stands that twist around each other in a spiral shape. Each strand consists of a sequence of nucleotide bases that pair up with the bases on the opposite strand, forming the characteristic double helix structure.
What make up both side of DNA double helix ladder?
The two sides of the DNA double helix ladder are made up of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The nitrogenous bases on opposite strands pair together through hydrogen bonding (adenine with thymine, and guanine with cytosine), holding the two sides of the ladder together.
How do you make a double helix model?
One way might be to get a flexible ladder and then turn both ends in opposite directions on its axis, in other words twist it. The result should be quite similar to a DNA double helix. You can use beads: http://www.instructables.com/id/The_Double_Helix_Glass_Bead_DNA_model/
What are the long chains that DNA make up?
DNA is made of two strands (chains) of DNA nucleotides that are twisted, forming a double helix, often compared to a twisted ladder. The two strands are held together by hydrogen bonds between the nitrogen bases.

What molecules come together to make a DNA molecule?
Nucleotides which formed double helix.
What is the processes of replication?
DNA replication simply means that DNA will split the double helix in two and refill its self. which then will make two of the same DNA strands.
In DNA molecule how many polynucleotide strands are present?
In a DNA molecule, two polynucleotide strands are present. These strands are arranged in a double helix structure, with each strand consisting of a sequence of nucleotides that are complementary to each other.
How many stands make up DNA double helix?
A DNA double helix is made up of two stands that twist around each other in a spiral shape. Each strand consists of a sequence of nucleotide bases that pair up with the bases on the opposite strand, forming the characteristic double helix structure.
What joins sugars to phosphate groups in nucleotides?
In nucleotides, sugars are joined to phosphate groups by phosphodiester bonds. This bond is formed between the 5' carbon of one sugar molecule and the 3' carbon of another sugar molecule, creating a sugar-phosphate backbone in DNA and RNA strands.

What are the 4 DNA nucleotides?
The four DNA nucleotides are adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides pair up with each other to form the base pairs that make up the DNA double helix.
What is the structure and function of a DNA strand molecule?
The structure of a DNA strand molecule is a double helix made up of two strands of nucleotides. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. The function of DNA is to store and transmit genetic information, which is encoded in the sequence of the nitrogenous bases along the strands. This information is used by cells to make proteins and carry out various biological processes.
