Which is the best definition for “expression of DNA”?Group of answer choicesUse of RNA to synthesize proteins.Use of DNA to synthesize RNA.Use of DNA to synthesize RNA followed (in most cases) by use of that RNA to synthesize proteins.Use of DNA to synthesize DNA that will be inherited by descendents (daughter cells).

What is "gene expression"?1 pointprocess by which DNA makes a copy of itself during cell division.the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteinsprocesses that convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP),the process by which the instructions in our DNA are converted into a functional product, such as a protein.RNA is synthesized on a DNA template in a process called:1 pointmethylationacetlyationtranscriptiontranslationThe enzyme that builds RNA from a DNA template1 pointDNA polymerasRNA polymeraseLigaseRNA primaseGyraseGiven the following DNA strand, which of the following is its complementary mRNA?

Which of the following statements about gene expression is NOT true?a) It is the process which ultimately leads to synthesis of a protein as encoded in theDNA.b) It can be ‘switched on’ or ‘switched off’ by regulatory factors.c) Gene expression of homeotic genes varies in time (i.e., age of the embryo) andspace (i.e., region of the embryo).d) House keeping genes are expressed intermittently

Which of the following best describes the process by which a protein-coding gene is expressed?Group of answer choicesDNA is chemically converted into RNA, which is then chemically converted into a protein molecule, all within the same cell.DNA is chemically converted into RNA, which is used as a template for building a protein molecule that is then transported to another cell.DNA is transported from one cell to another, where it is chemically converted first into RNA and then into a protein molecule.DNA is used as a template to build a new RNA strand, which is used as a template to build a protein molecule, all within the same cell.DNA is used as a template to build a new RNA strand, which is transported to another cell and then chemically converted into a protein molecule.Next

If DNA directs the production of RNA, what does RNA make?Group of answer choicesRNA makes hereditary molecules.RNA makes membranes.RNA makes proteins.RNA makes more DNA.
