EXPRESSION AND GENETIC ANALYSIS
METHODS

◉ Genetics. Answer: The brand of biology that deals with heredity
and variation


◉ Gene. Answer: A segment of DNA that has the information to
produce a functional product


◉ Traits. Answer: The characteristics of an organism


◉ Macromolecule. Answer: Molecules composed of many repeating
units of smaller building blocks


◉ Organelle. Answer: A membrane bound compartment with a
specialized function


◉ Proteome. Answer: All of the proteins that a cell or organism
makes at a given time

, ◉ Enzymes. Answer: Proteins that accelerate chemical reactions


◉ Nucleotide. Answer: The basic structural unit of DNA


◉ Genetic Code. Answer: Contain the information to direct the order
of amino acids within polypeptides


◉ Chromosome. Answer: A linear, double stranded structure that
contains well over a hundred million nucleotides. It contains the
genetic information of the cell


◉ Gene Expression. Answer: The process of using a gene sequence
to affect the characteristics of cells and organisms


◉ Transcription. Answer: The DNA sequence within a gene is copied
into a nucleotide sequence of ribonucleic acid (RNA). Most genes
encode for RNA that can synthesize messenger RNA (mRNA)


◉ Translation. Answer: The sequence of nucleotides in an mRNA
provides the information (using the genetic code) to produce the
amino acid sequence of a polypeptide (results in proteins)


◉ Messanger RNA (mRNA). Answer: RNA that contains the
information for the synthesis of a particular polypeptide
