DNA is a polymer. The monomeric units of DNA are nucleotides, and the polymers are called « polynucleotide. » Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogenous base attached to the sugar, and a phosphate group.

What describes the structure of DNA?

DNA is a molecule that holds the growth and development instructions for every living thing.Its structure is described as double-stranded helix held together by complementary base pairs. The basic unit of DNA is the nucleotide. These nucleotides are composed of deoxyribose, phosphates and bases.

What is the polymer structure of DNA?

DNA consists of two long polymers (called share) run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose), and a phosphate residue.

Are nucleotides polymers of DNA?

Nucleotides

RNA and DNA are made of polymers long chain nucleotides. Nucleotides consist of sugar molecules (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogenous base.

What is the nucleotide structure of DNA?

Each nucleotide consists of a Heterocyclic base linked to a phosphate group through a five-carbon sugar (deoxyribose or ribose) (See Figure 4-1). DNA and RNA each contain four different bases (see Figure 4-2). The purines adenine (A) and guanine (G) and pyrimidine cytosine (C) are found in DNA and RNA.

What color is DNA in real life?

Figure 1: A single nucleotide contains a nitrogenous base (red), a deoxyribose molecule (grey), and a phosphate group attached to the 5′ side of the sugar (shown in light grey). Opposite the 5′ side of the sugar molecule is the 3′ side (dark grey) to which free hydroxyl groups are attached (not shown).

What is DNA and its structure?

DNA is a twisted-looking double-stranded molecule, giving it its unique shape, called a double helix. Each of the two strands is a long sequence of nucleotides or a single unit consisting of a phosphate molecule. A sugar molecule called deoxyribose, which contains five carbon atoms.

What are the two main classes of polymers?

Polymers fall into two categories:

• Thermoset or thermoset plastic.
• Thermoformed plastic or thermoplastic.

What is a polymer of nucleotides called?

The monomeric units of DNA are nucleotides, and the polymers are called a « polynucleotide ». » Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogenous base attached to the sugar, and a phosphate group.

Are nucleic acids polymers?

nucleic acid is a macromolecule Consists of repeating units of monomeric « nucleotides » consisting of a nitrogen-containing heterocyclic base (purine or pyrimidine), a pentose (five-carbon) sugar (ribose or 2′-deoxyribose), and one to three consisting of phosphate groups.

Why is DNA a polymer?

DNA is a A polymer made from four different monomers , called nucleotides. They are linked together in different combinations to form long chains. In a DNA molecule, two strands twist around each other to form a double helix.

What is the evidence that DNA is a polymer?

What is the evidence from the diagram that DNA is a polymer? DNA is a polymer Since it contains multiple repeating units (monomers). These monomers are called nucleotides. Multiple nucleotides are linked together by phosphodiester bonds to form a polymer, DNA.

Is DNA a monomer or a polymer?

even our DNA polymer– It consists of monomers called nucleotides.

How many parts are there in DNA?

DNA is made up of chemical building blocks called nucleotides.These blocks are made of three parts: Phosphate group, sugar group and one of the four nitrogen bases. To form a DNA strand, nucleotides are linked into chains with alternating phosphate groups and sugar groups.

What are the 3 types of DNA?

The three major forms of DNA are double-stranded and linked by interactions between complementary base pairs.these are the terms A, B, and Z DNA.

What are the 3 functions of DNA?

DNA now has three different functions –Genetics, Immunology and Structure– They vary widely and depend on the sugar phosphate backbone and bases.

Are amino acids monomers or polymers?

Biomacromolecules are large biopolymers, such as nucleic acids, proteins, and carbohydrates, composed of monomer link together. For example, proteins are made up of monomers called amino acids.

Are ribonucleotides polymers?

One RNA polymer is a string of ribonucleotides, each made up of three distinct parts: a ribose sugar, a phosphate group, and a base — a cytosine or uracil, called a pyrimidine, or a purine, guanine or adenine.

Are amino acids a polymer?

Poly(amino acids) are A polymer composed of amino acids as monomer units. Structural and functional proteins, polypeptides, peptides and polymers derived from amino acids, namely poly(β-alanine) and ɛ-poly(lysine), are classified as poly(amino acids).

On what basis are polymers classified?

The most common way to classify polymers is to divide them into three groups – Thermoplastics, Thermosets and Elastomers. Thermoplastics can be divided into two types – crystalline and amorphous.

What are the 4 polymers?

terms. Synthetic polymers are man-made polymers. From a utility standpoint, they can be grouped into four broad categories: Thermoplastics, Thermosets, Elastomers and Synthetic Fibers.

What is DNA short answer?

DNA, or DNA, is the genetic material of humans and almost all other organisms. Almost every cell in the human body has the same DNA. The information in DNA is stored as a code consisting of four chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T).

What are the 4 types of DNA?

Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

What are DNA full details?

DNA, commonly known as DNA, is a complex molecule that contains all the information needed to build and maintain an organism. All living things have DNA inside their cells. In fact, nearly every cell in a multicellular organism possesses the complete set of DNA that the organism needs.
