What is the difference between an endonuclease and an exonuclease?
an exonuclease cleaves nucleotides from the end of a polynucleotide chain whereas an endonuclease cleaves nucleotides from within a polynucleotide chain
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 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.
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 (protein) is determined by the order of nucleotide triplets in the messenger RNA, or mRNA, chain that was transcribed from the DNA inside the nucleus for that specific protein.
What is a subunit of a nucleic acid?
The subunit of a nucleic acid are nucleotides.
A molecular chain of nucleotides?
Polynucleotides is a chemical way to refering to DNA or RNA. The backbone of a DNA or RNA is an alternating sequence of sugars and phosphates. If the chain is DNA the sugar is deoxyribonucleic acid. If the chain if RNA, the sugar is ribonucleic acid.
RNA consists of a long chain of?
nucleotides
What is the difference between an endonuclease and an exonuclease?
an exonuclease cleaves nucleotides from the end of a polynucleotide chain whereas an endonuclease cleaves nucleotides from within a polynucleotide chain
Molecules of DNA are composed of a long chain are called?
A DNA molecule is composed of long chains of DNA 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.
What is the basic building block of a nucleic-acid chain?
Nucleotides.
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 are the major components of a DNA molecular subunit?
Nucleotides are composed of a nitrogenous base, a pentose sugar, and a phosphate group.
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.
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.
Is a short-chain hydrocarbon more viscous than a long chain hydrocarbon?
Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.
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.
