The building block of a nucleic acid, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group.
a base found in DNA (but not in RNA) and derived from pyrimidine
One of the four aromatic bases found in DNA and RNA. Guanine is a purine; it pairs with cytosine.
a nitrogen-containing base found in RNA (but not in DNA) and derived from pyrimidine
messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome
region of DNA that indicates to an enzyme where to bind to make RNA
basic building blocks of protein molecules
principle that bonds in DNA can form only between adenine and thymine and betwen guanine and cytosine
a base found in DNA and RNA and derived from pyrimidine
enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule
the biochemical units of heredity that make up the chromosomes; a segment of DNA capable of synthesizing a protein
ribosomal RNA; type of RNA that makes up part of the ribosome
sequence of DNA that is not involved in coding for a protein
macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed by the body for growth and repair and to make up enzymes
nitrogen base found in DNA and RNA; pairs with thymine in DNA and with uracil in RNA
five-carbon sugar that is a component of DNA nucleotides
repetitive DNA at the end of a eukaryotic chromosome
(genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA
short-chain RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according
sequence of a gene's DNA that transcribes into protein structures
The bases of DNA that contain Carbon, Hydrogen, Oxygen, and Nitrogen which includes: Adenine, Thymine,Cytosine, and Guanine.
an enzyme in eukaryotic cells that can add telomeres to the ends of chromosomes after they divide
enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription
