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.
Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The phosphate group can be removed from a nucleotide without breaking the polynucleotide chain within a DNA molecule. The phosphate group is attached to the 5' carbon of the sugar molecule in a nucleotide through a phosphodiester bond, which does not affect the backbone of the DNA chain when cleaved.
What is the polymer of dna known as?
The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
What is the definition of DNA molecule?
Consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine
What are the four chemicals that hold together DNA molecule?
If by "four chemicals" you mean nucleotides, then they are as follows: 1. deoxyadenosine monophosphate or adenine 2. deoxyguanosine monophosphate or guanine 3. deoxycytosine monophosphate or cytidine 4. deoxythymine monophosphate or thymidine The chemical bonds holding DNA molecules together are 1. phosphodiester bond in the polynucleotide strand 2. hydrogen bond between the complementary nitrogenous bases on adjacent polynucleotide 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.
What is the monomer of the polynucleotide molecule called?
The monomer of a polynucleotide molecule is called a nucleotide. It consists of three components: a phosphate group, a sugar (deoxyribose in DNA or ribose in RNA), and a nitrogenous base (adenine, thymine, cytosine, guanine in DNA; adenine, uracil, cytosine, guanine in RNA).
What is a polynucleotide?
Polynucleotide is a molecule that is usually in DNA and RNA. It is biopolymer composed and usually has thirteen or more nucleotides.
Which component of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
all i know is that its not phosphate
What Type of polynucleotide acting as messenger?
Messenger RNA (mRNA) acts as the polynucleotide that carries genetic information from DNA to the ribosomes in the cell. It is involved in the process of protein synthesis, where the information encoded in mRNA is translated into a specific protein by the ribosomes.
How many polynucleotide chains are in each DNA molecule?
hundreds and thousands =) : im looking at my book right now because i also needed this answer.
What is the job of nucleotide?
A nucleotide is the monomer of a nucleic acid. When many nucleotides go through polymerization, then they create a polymer called a polynucleotide. Which are the building blocks for DNA and RNA.
What do polynuceotides do?
Polynucleotides are macromolecules made up of nucleotide monomers. They play a crucial role in storing, transmitting, and expressing genetic information in living organisms. DNA and RNA are examples of polynucleotides that carry genetic instructions for the synthesis of proteins.
What type of bonding holds the two poly nucleotide strands of a DNA molecule together?
The two polynucleotide strands of a DNA molecule are held together by hydrogen bonds between complementary bases. Adenine pairs with thymine and guanine pairs with cytosine. This base-pairing contributes to the structural stability of the DNA molecule.
Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The phosphate group can be removed from a nucleotide without breaking the polynucleotide chain within a DNA molecule. The phosphate group is attached to the 5' carbon of the sugar molecule in a nucleotide through a phosphodiester bond, which does not affect the backbone of the DNA chain when cleaved.
Name of substance that DNA is composed of?
DNA (deoxyribonucleic acid) is a double stranded polynucleotide. It is made of two anti-parallel strands of many individual units called nucleotides joined together. The nucleotides themselves consist of a phosphate group, a pentose sugar (in the nucleotides of DNA the pentose sugar present is deoxyribose) and a nitrogenous base (in the nucleotides of DNA the bases are adenine, thymine, guanine and cytosine).
What is the polymer of dna known as?
The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
