Essential vocabulary for the IBO DP Biology course
Terms in this set (14)
an organic base found in DNA and RNA in which it pairs with thymine (or uracil).
Complementary base pairs
the standard arrangement of bases in nucleotides in relation to their opposite pairing, such as cytosine paired with guanine and adenine with thymine (or uracil in RNA).
an organic base found in DNA and RNA in which it pairs with guanine.
an enzyme that catalyses the elongation of new DNA during replication.
a nucleic acid consisting of two long chains of nucleotides twisted into a double helix that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.
an organic base found in DNA and RNA in which it pairs with cytosine.
a chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom of another molecule.
Nucleic acids biological
molecules, such as DNA or RNA, composed of nucleotides that control cellular functions and heredity.
the building blocks of nucleic acids consisting of a five-carbon sugar, a nitrogenous base, and a phosphate group.
a large molecule consisting of many identical or similar monomers linked together.
a nucleic acid consisting of a long single-stranded chain of nucleotides involved in protein synthesis.
an enzyme that links together the growing chain of RNA during transcription.
an organic base found in DNA, but not in RNA, that pairs with adenine.
a nitrogen-containing base found in RNA, but not in DNA, that pairs with adenine.
