How many polynucleotide strands do RNA have?
RNA typically consists of a single polynucleotide strand.
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.
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 make up the backbone of a polynucleotide strand?
The backbone of a polynucleotide strand is composed of alternating sugar (deoxyribose or ribose) and phosphate molecules. The sugar-phosphate backbone provides the structural support for the nucleotide bases, which extend from the backbone and form interactions with bases on the opposite strand in DNA or RNA molecules.
What is the difference between an endonuclease and an exonuclease?
An endonuclease cleaves nucleic acids internally at specific recognition sites, while an exonuclease cleaves nucleic acids at the ends by removing nucleotides one at a time. Endonucleases are involved in processes like DNA repair and recombination, while exonucleases are important for proofreading during DNA replication.
How many polynucleotide strands do RNA have?
RNA typically consists of a single polynucleotide strand.
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.
The struct of RNA?
RNA is a single polynucleotide chain.
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.
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.
What has the author Roshan Shafai written?
Roshan Shafai has written: 'The polynucleotide structure of a germin gene'
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.
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

The sugar-phosphate backbone provides the structural support for the nucleotide bases, which extend from the backbone and form interactions with bases on the opposite strand in DNA or RNA molecules.
What bonds form a polynucleotide strand?
A polynucleotide strand forms from covalent bonds known as phosphodiester bonds, which link together the individual nucleotides (composed of a sugar, phosphate group, and nitrogenous base). These phosphodiester bonds connect the 3' carbon of one nucleotide to the 5' carbon of the next nucleotide in the strand, creating a linear chain.
What is created when nucleotides join together into a polynucleotide?
When nucleotides join together into a polynucleotide, they form a long chain known as a nucleic acid, such as DNA or RNA. This process involves the formation of phosphodiester bonds between the sugar of one nucleotide and the phosphate group of another, creating a backbone that holds the sequence of nitrogenous bases. The specific arrangement of these bases encodes genetic information essential for biological functions.
