What would DNA be classified as?
DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.
Is DNA A complex compound?
In short, DNA is a complex molecule that consists of many components, a portion of which are passed from parent organisms to their offspring during the process of reproduction. Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules.
Is DNA an organelle?
The three organelles that contain DNA are the nucleus, mitochondria and chloroplasts. The nucleus is the control center of the cell, and houses genetic information. The mitochondria and chloroplasts both produce energy, in animal and plant cells, respectively.
Is DNA A molecule?
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells.
Is DNA A biology or A chemical?
Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis. It is found in most cells of every organism. DNA is a key part of reproduction in which genetic heredity occurs through the passing down of DNA from parent or parents to offspring.
Is DNA a molecule?
Is DNA circular or linear?
Linear DNA is the form of DNA present in the eukaryotic nucleus and is composed of two free ends. Circular DNA is the DNA having a closed conformation and found in the cytoplasm of the prokaryotic cell, mitochondria or chloroplast. Linear DNA is found in the nucleus of eukaryotes.
Is DNA a polymer?
The proteins we eat, and which we’re made of, are polymers made up of amino acids. And even our DNA is a polymer—it’s made of monomers called nucleotides.
What is the chemistry of DNA?
DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
What is linear DNA?
Linear DNA is the form of DNA present in the eukaryotic nucleus and is composed of two free ends. Circular DNA is predominantly found in prokaryotes, whereas the mitochondria, chloroplast and plasmids also contain circular DNA.
Why is DNA linear?
In most eukaryotic cells, DNA is arranged in multiple linear chromosomes. One potential selective pressure in favor of linear chromosomes relates to the size of an organism’s genome: linear chromosomes may make transcription and replication of large genomes easier.
Is DNA an organic or inorganic compound?
Organic compounds are those which contain carbon along with some other elements. DNA is made up of Nucleic acids . They are Adenine , Guanine , Thymine and Cytosine . These Nucleic acids contain sugar moiety which is made up of carbon. Thus, DNA can be considered as an organic compound.
What are the components of DNA called?
What is the backbone of the DNA molecule is made up two components what are these? A DNA molecule is made up of numerous genes and are found on chromosomes. DNA contains monomers called nucleotides, which is made up of a phosphate group, a deoxyribose sugar,… and a nitrogenous base.
What does an a DNA molecule consist of?
DNA is made up of molecules called nucleotides . Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
What chemicals are in DNA?
DNA is composed of four chemicals: cytosine, guanine, thymine and adenine. Our cells are made up of DNA, which is strung together in chromosomes. We have our parents to thank for these chromosomes — 23 pairs from each.
