How many strands does DNA have what is its shape?
DNA has two strands that form a double helix shape. The double helix structure is like a twisted ladder, with two strands of nucleotides connected by hydrogen bonds and coiled around each other.
What are the two long chains in the DNA called?
The two long chains in DNA are called nucleotide strands. These strands are made up of smaller units called nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The nucleotide strands are complementary and form a double helix structure.
The double helix is made up of a series of what that are linked together?
The double helix is made up of a series of nucleotides that are linked together. Each nucleotide consists of a phosphate group, a sugar molecule, and a nitrogenous base. These nucleotides form the building blocks of DNA strands.
What The type of bond that links two nucleotides between two different strands of DNA is known?
The type of bond that links two nucleotides between two different strands of DNA is known as a hydrogen bond. These bonds form between complementary nitrogenous bases—adenine pairs with thymine, and cytosine pairs with guanine—holding the two strands of the DNA double helix together. Hydrogen bonds are relatively weak compared to covalent bonds, allowing the DNA strands to separate during processes such as replication and transcription.
What is an RNA nucleotide?
An RNA nucleotide is the building block of RNA, consisting of a nitrogenous base (adenine, guanine, cytosine, or uracil), a ribose sugar, and a phosphate group. These nucleotides are linked together to form RNA strands during transcription.
How does the Cell's nucleus get the new nucleotides that are necessary to form new Rna and DNA?
Nucleotides are assembled from raw materials and precursors. New DNA and Rna strands RESULT mainly from nucleotide RECYCLING!
DNA molecules has how many strands?
DNA molecules have two strands that are twisted together to form a double helix structure. Each strand is made up of a sequence of nucleotides containing genetic information.
How many strands does DNA have what is its shape?
DNA has two strands that form a double helix shape. The double helix structure is like a twisted ladder, with two strands of nucleotides connected by hydrogen bonds and coiled around each other.
How did James Watson discover DNA?
James Watson and Francis Crick discoverd the two strands of nucleotides that form a twisted ladder (double helix) in DNA

Is DNA a single stranded molecule?
Yes, DNA is double-stranded.There are two strands. Each one is a polymer (series) of nucleotides, and the two strands twine round one another to form the DNA molecule.
What is an RNA nucleotide?
An RNA nucleotide is the building block of RNA, consisting of a nitrogenous base (adenine, guanine, cytosine, or uracil), a ribose sugar, and a phosphate group. These nucleotides are linked together to form RNA strands during transcription.
What are the strands of the DNA ladder made of?
The strands of the DNA ladder are made of nucleotides, which consist of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). These nucleotides join together to form the double helix structure of DNA.
How do you describe the basic structure of the DNA molecules?
DNA is composed of two strands of DNA nucleotides, arranged into a double helix, often referred to as a twisted ladder. The sides of the ladder are composed of alternating deoxyribose sugar molecules and phosphate molecules, and the rungs of the ladder are the pairs of nitrogen bases. The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.
Is DNA a single strand of nucleotides?
No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.
