What else can I help you with?
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 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).
Is sugar a component of a nucleotide?
No, sugar is not a component of a nucleotide. Nucleotides consist of a sugar molecule, a phosphate group, and a nitrogenous base.
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 a polynucleotide?
Polynucleotide is a molecule that is usually in DNA and RNA. It is biopolymer composed and usually has thirteen or more nucleotides.
What sugar is a componenet part of a DNA nucleotide?
The sugar deoxyribose is a component of a DNA nucleotide.
Which structure is not a component of a nucleotide?
Amino acid is not a component of a nucleotide. Nucleotides are made up of a phosphate group, a sugar molecule, and a nitrogenous base. Amino acids are the building blocks of proteins, not nucleotides.
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.
Why is DNA called polynucleotide?
DNA is called a polynucleotide because it is composed of multiple nucleotides linked together in a chain. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base, and when these nucleotides join together through phosphodiester bonds, they form a long chain called a polynucleotide.
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 component of DNA carries the gentic code?
The genetic code is carried by the sequences of nucleotide bases in the DNA molecule. These bases are adenine (A), thymine (T), cytosine (C), and guanine (G). The specific order of these bases determines the genetic information encoded in DNA.
What does 'deoxyribo ' stand for?
It means that the sugar in a molecule is deoxyribose.So, for example, deoxyribonucleic acid (DNA) means "the nucleic acid that has deoxyribose as the sugar component of every nucleotide in its molecule".
