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.
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.
What can you say about the direction of the strands of nucleotides that make up DNA molecule?
The two strands of nucleotides in a DNA molecule run in opposite directions, referred to as antiparallel. This means that one strand runs in a 5' to 3' direction while the other runs in a 3' to 5' direction. This arrangement is essential for DNA replication and other cellular processes.
What holdes the two strands of a DNA molecule to each other?
Hydrogen bonds
How would you describe the polymerization of nucleotides?
Nucleotides polymerize by forming phosphodiester bonds between the sugar of one nucleotide and the phosphate group of another, creating a chain. This process is catalyzed by enzymes called polymerases. The resulting polymer is called a nucleic acid, such as DNA or RNA.
The strict arrangement of base-pairings in the double helix results in two strands of nucleotides that are?
complimentary to each other
Which best describes the structure of a DNA molecule-?
a double helix- apex
How many strands does DNA have what is its shape?

When two nucleotides are joined to each other, what is the resulting structure called?
When two nucleotides are joined together, the resulting structure is called a dinucleotide.
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 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 strands of nucleotides make up DNA double helix?
A DNA double helix is made up of two strands of nucleotides that are complementary to each other. Each strand consists of a sequence of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
How are proteins involved in the process of DNA replication?
During DNA replication, proteins called DNA polymerases help to copy the DNA strands by adding new nucleotides to the existing strands. Other proteins, like helicases and topoisomerases, unwind and stabilize the DNA strands to allow for replication to occur smoothly. Proteins also help in proofreading and repairing any mistakes that may occur during the replication process.
Is DNA and RNA double stranded?
DNA is double stranded, meaning it consists of two strands of nucleotides that are connected together. RNA, on the other hand, is typically single stranded.
What can you say about the direction of the strands of nucleotides that make up DNA molecule?
The two strands of nucleotides in a DNA molecule run in opposite directions, referred to as antiparallel. This means that one strand runs in a 5' to 3' direction while the other runs in a 3' to 5' direction. This arrangement is essential for DNA replication and other cellular processes.
What are the two pieces of information from other scientists that enabled James Watson and Francis Crick to discover helical structure of DNA?
the two strands of nucleotides twisting around a central axis.
Number of nucleotide strands in RNA?
RNA is typically composed of a single nucleotide strand, unlike DNA which is composed of two complementary strands. Each nucleotide in RNA consists of a sugar, a phosphate group, and one of four nitrogenous bases (adenine, cytosine, guanine, or uracil).
