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 forms the back bone of a DNA chain?
The backbone of a DNA chain is formed by alternating sugar (deoxyribose) and phosphate molecules, running in a repeating pattern. The sugar-phosphate backbone provides structural support to the DNA double helix and helps to maintain the overall shape of the molecule.
The coiling of the protein chain backbone into an alpha helix is referred to as?
The coiling of the protein chain backbone into an alpha helix is referred to as secondary structure. This repetitive structure is stabilized by hydrogen bonds between the backbone amide hydrogen and carbonyl oxygen atoms.
What are the building blocks of starch?
Starch is made up of two main building blocks: amylose and amylopectin. Amylose is a linear chain of glucose molecules, while amylopectin is a branched chain of glucose molecules. These two components combine to form the complex structure of starch.
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 a polynucleotide?
Polynucleotide is a molecule that is usually in DNA and RNA. It is biopolymer composed and usually has thirteen or more nucleotides.
The struct of RNA?
RNA is a single polynucleotide chain.
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 two molecules form a long chain with what kind of backbone?
Manly two king of living thing lipids and proteins
What is an example of a sugar phosphate backbone?
DNA and RNA molecules have a sugar phosphate backbone. In DNA, the sugar is deoxyribose, while in RNA it is ribose. The phosphate groups link the sugar molecules together forming a linear chain.
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 forms the back bone of a DNA chain?
The backbone of a DNA chain is formed by alternating sugar (deoxyribose) and phosphate molecules, running in a repeating pattern. The sugar-phosphate backbone provides structural support to the DNA double helix and helps to maintain the overall shape of the molecule.
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
Backbone of Italy?
The Appennino Mountain Chain.
What forms the backbone of the DNA double helix molecule?
The backbone of a DNA chain is sugar and phosphate groups of each nucleotide.
Do carbohydrates usually have a hydrocarbon chain?
Yes, carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms. They typically have a backbone of carbon atoms bonded to each other, forming a chain or ring structure.
What is an example of chain molecules?
An example of chain molecules would be...
