A molecular chain of nucleotides is a sequence of nucleotide units linked together. Nucleotides are the building blocks of nucleic acids like DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base. When these nucleotides are connected in a specific order, they form a nucleic acid chain that carries genetic information.

Individual chains of the DNA double helix are made up of molecules called?
nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). These nucleotides are linked together by covalent bonds to form the backbone of the DNA chain.
The order of the amino acids in a polypeptide chain are determind by the order of nucleotides in the what?
The order of amino acids in a polypeptide chain is determined by the sequence of nucleotides in the mRNA (messenger RNA) molecule. This sequence is read during the process of translation by the ribosome, which then assembles the corresponding amino acids in the correct order to form the polypeptide chain.
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.
What is the number of nucleotides found in a protein?
None! The reason is: there are no nucleotides in proteins. Nucleotides are the monomers (building blocks) of nucleic acids. The monomers of proteins are amino acids. The relationship between nucleotides and amino acids is the genetic code. In brief, the genetic code works like this: within a region of DNA that codes for a polypeptide chain (from which a protein will be made) a group of three adjacent nucleotides code for one amino acid.
What is the linear sequence of amino acids in a polypeptide chain is called?
The linear sequence of amino acids in a polypeptide chain is called the primary structure. It is determined by the specific order of amino acids in the chain, which is encoded by the sequence of nucleotides in the gene that codes for the protein.
A molecular chain of nucleotides?
A molecular chain of nucleotides is a sequence of nucleotides joined together by phosphodiester bonds. Nucleotides are the building blocks of DNA and RNA, consisting of a nitrogenous base, a sugar molecule, and a phosphate group. The sequence of nucleotides in a chain determines the genetic information encoded in the molecule.
Molecules of DNA are composed of a long chain are called?
Molecules of DNA are composed of a long chain of nucleotides.
RNA consists of a long chain of?
nucleotides
The number of nucleotides required to specify an amino acid is?
Three nucleotides are required for an amino acid. These nucleotides are an amine, carbolic acid, and a side chain specific to the amino acid.
Number of chains of nucleotides in RNA?
RNA is composed of a single strand of nucleotides, which are typically represented by the letters A, U, G, and C. Therefore, RNA consists of one chain of nucleotides.
What is the molecular weight of the alpha 1 chain in type V collagen?
The alpha 1 chain in type V collagen has a molecular weight of approximately 140 kDa.
Are nucleic acids and nucleotides the same thing?
No, nucleic acids are biopolymers made up of nucleotides linked together in a chain. Nucleotides are the building blocks of nucleic acids, consisting of a phosphate group, a sugar molecule, and a nitrogenous base.
How do you distinguish between a macro-molecular from molecular?
A macromolecule is formed from many molecules linked together in a chain and of course has a higher molecular mass.
Individual chains of the DNA double helix are made up of molecules called?
nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). These nucleotides are linked together by covalent bonds to form the backbone of the DNA chain.
What will be the molecular weight of poly A chain having 100 residues where AMP has weight of 300?
The molecular weight of poly A chain with 100 residues can be calculated by adding the molecular weight of each residue. Since each residue is AMP (adenosine monophosphate) with a weight of 300, the total molecular weight of the poly A chain would be 300 x 100 = 30,000.
What constitute a long chain of simple sugars?
Polysaccharide constitutes a long chain of simple sugars. The genetic information is coded in DNA by the sequence of the nucleotides.
DNA is a long chain of what smaller molecules?
DNA is a long chain of nucleotides, which contain a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). These nucleotides are arranged in a specific sequence to encode genetic information.
