Ch. 15 Vocabulary


Base pair A and T and C and G align with each other on opposite strands of the double-stranded DNA
Bidirectional gene therapy (blank)
Chromosome very large circular molecule of several million base pairs of DNA
Complementary DNA has nucleotides on one strand that match up with specific nucleotides on the other strand--provided that A & T always base pair and C&G always base pair
Diploid eukaryotes--have 2 copies of each chromosome
DNase enzyme that degrades DNA
Genetic engineering overall processes of changing the normal genetic character of an individual or providing new gene products
Genetics study of the heredity (how genes are passed from one generation to the next), variation, and expression of genes
Genome collection of all genes in a cell
Haploid prokaryotes--contain one copy of each chromosome
Heredity how genes are passed from one generation to the next
Mutant strain a gene required to produce the capsule was defective
Origin of replication direct site of each chromosome that signals the enzymes the proper location to begin replication
Proofread polymerase checks newly added nucleotides--is A opposite a T in the template--G opposite C--if base pair not proper--polymerase removes it and tries again to add the correct one
Protease (proteinase) enzyme that degrades protein, and RNase degrades RNA
Proteinase (protease) enzyme that degrades protein, and RNase degrades RNA
Recombinant DNA technology series of tools, enzymes, and bacterial hosts--allow researchers to isolate and identify the mutant adenine deaminase (ADA) gene
Replication enzymatic process of making another copy, or dublicate
RNase degrades RNA
Transfection when virus carries foreign DNA--term transfect is used in place of infect
Transforming principle Griffith showed genes can functionally affect character of cells--genes can be transferred from one cell to another
viral vectors delivery system called a vector--most widely used vectors for gene therapy are viruses
Wild-type bacterium bacterium lacking mutations--had a capsule
