BIO 12-MOD1/1.2E

Lesson 1.2E Vocabulary Words

TermDefinition
adenosine triphosphate (ATP) (ATP) high-energy molecules used by the cell to synthesize macromolecules, such as carbohydrates and proteins
complementary base pairing Complementary base pairing describes the manner in which the nitrogenous bases of the DNA molecules align with each other. Complementary base pairings are also responsible for the double-helix structure of DNA.
cytosine (C) One of four nitrogen-containing bases in nucleotides composing the structure of DNA and RNA; pairs with guanine.
deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses
double helix describes the appearance of a DNA molecule
guanine (G) Double spiral; describes the three-dimensional shape of DNA.
ribonucleic acid (RNA) Nucleic acid produced from covalent bonding of nucleotide monomers that contain the sugar ribose; occurs in three forms: messenger RNA, ribosomal RNA, and transfer RNA.
nitrogenous base is simply a nitrogen containing molecule that has the same chemical properties as a base. They are particularly important since they make up the building blocks of DNA and RNA: adenine, guanine, cytosine, thymine and uracil.
nucleic acids there are two types of nucleic acids; DNA and RNA; both are polymers of nucleotides
nucleotide composed of three main parts: a phosphate group (phosphoric acid), a pentose sugar (DNA contains the sugar deoxyribose and RNA contains the sugar ribose), and a nitrogen-containing base
phosphate (PO43−) as an inorganic chemical is a salt of phosphoric acid. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid.
thymine (T) (T) One of four nitrogen-containing bases in nucleotides composing the structure of DNA; pairs with adenine.
uracil (U) (U) One of four nitrogen-containing structures of RNA; pairs with adenine.
