Guide with Complete Solutions
gene expression - Answer✔️✔️-The process by which DNA directs the synthesis of
proteins or, in some cases, just RNAs. Includes 2 stages - transcription and translation
Garrod - Answer✔️✔️-scientist who was the first to say in 1909 that genes determine
phenotype through the production of enzymes that catalyze chemical reactions;
diseases caused by missing enzymes are "inborn errors of metabolism"
Beadle and Tatum - Answer✔️✔️-Exposed bread mold to X-rays, creating mutants.
Showed that each gene encodes a particular substance ("one gene, one enzyme"
concept, later restated "one gene one polypeptide").
transcription - Answer✔️✔️-process by which a DNA template is used to produce a
single-stranded RNA molecule
messenger RNA - Answer✔️✔️-RNA molecule that carries copies of instructions for the
assembly of amino acids into proteins from DNA to the rest of the cell
translation - Answer✔️✔️-Decoding of a mRNA message into a polypeptide chain
ribosomes - Answer✔️✔️-sites of translation
primary transcript - Answer✔️✔️-the initial RNA transcript from any gene, including those
specifying RNA that is not translated into protein
triplet code - Answer✔️✔️-the normal version of the genetic code in which a sequence of
