The double-stranded DNA molecule is held together by four chemical components called bases. Horse isle Real Time Quiz Answer: Bases
The backbone of a DNA molecule is composed of 1:1 molecular phosphoric acid and deoxyribose, together with the base (A, T, C, or G) is called a nucleotide. While the backbone of a RNA molecule is composed of 1:1 molecular phosphoric acid and ribose.
no
Cytosine is always coupled with Guanine. (I like to remember that the round letters stick together).In DNA, Thymine is coupled with Adenine, but in RNA, Thymine is replaced by Uracil.Therefore, in RNA, U and A go together, always.
Adenine and Thymine together and cytosine and guanine together.
The chemical process by which a molecule of water is removed from the reactants to join the reactants together. Dehydration synthesis takes place when the monomers of organic compounds join together by a chemical reaction to make polymers. Hydrolysis its the opposite reaction of breaking up polymers and is accomplished also by chemical reaction. "The joining of two molecules associated with the removal of a water molecule" -Fundamentals of Anatomy and Physiology 7th ed.
chemical bonds
The atoms of a molecule stay together with chemical bonds.
molecule
Each molecule has a specific structure.
Two or more atoms that get together and share electrons form a chemical bond.
Atoms are linked in a molecule by chemical bondings.The chemical bondings are: ionic, covalent and metallic bonding in metals.
A molecule a group of atoms bonded together, representative of the smallest essential unit of a chemical compound that can take part in a chemical reaction.
What components make up the backbone of DNA
a molecule
This is a chemical compound (molecule).
Molecules are composed of atoms, which are held together by sharing their outer electrons in covalent bonds. Glucose is the most common biological molecule on Earth.
A molecule is not an unique entity. It is common to any substance. Any no. of atom which combine together by chemical bonds form a molecule. The melting point of any molecule depends upon its chemical composition.
