10 consensus sequence-consensus sequence found in most bacterial promoters approximately 10 bp upstream of the transcription start site 3 prime splice site-the 3’ end of an intron where cleavage takes place in RNA splicing 3 prime untranslated region-sequences of nucleotides at the 3’ end of mRNA; does not code for the amino acids of a protein but affects both the stability of the mRNA and its traslation 30S initiation complex -35 consensus sequence-consensus sequences found in many bacterial promoters approximately 35 bp upstream of the transcription start site 5 prime cap-modified 5’ end of eukaryotic mRNA, consisting of an extra nucleotide and methylation of the 2’ position of the sugar in one or more subsequent nucleotides; plays a role in the binding of the ribosome to mRNA and affects mRNA stability and the removal of introns 5 prime splice site-the 5’ end of an intron where cleavage takes place in RNA splicing 5 prime untranslated region-sequence of nucleotides at the 5’ end of mRNA; does not code for the amino acids of a protein 70S initiation complex Adaptive mutation-processes by which a specific environment induces mutations that enable organisms to adapt to the environment Allosteric protein-protein that changes its conformation on binding with another molecule Alternative processing pathway-one of several pathways by which a single pre-mRNA can be processed in different ways to produce alternative types of mRNA Alternative splicing-process by which a single pre-mRNA can be splieced in more than one way to produce different types of mRNA Ames test-test in which special strains of bacteria are sued to evaluate the potential of chemicals to cause cancer Amino acid-repeating unit of proteins; consists of an amino group, a carboxyl group, a hydrogen atom, and a variable R group Aminoacyl site-one of three sites in a ribosome occupied by a tRNA in translation. All charged tRNAs first enter the A site in translation Aminoacyl tRNA synthetase-enzyme that attaches an amino acid to a tRNA. Each aminoacyl-tRNA synthestase is specific for a particular amino acid Anticodon-sequence of three nucleotides in tRNA that pairs with the corresponding codon in mRNA in translation Antisense RNA-small RNA molecule that base pairs with a complementary DNA or RNA sequence and affects is functioning Antiterminator-protein or DNA sequence that inhibits the termination of transcription Attenuation-type of gene regulation in some bacterial operons, in which transcription is initiated but terminates prematurely before transcription of the structural genes Attenuator-secondary structure that forms in the 5’ untranslated region of some operons and causes the premature termination of transcription Autonomously replicating sequence-DNA sequence that confers the ability to replicate; contains an origin of replication Auxotroph-bacterium or fungus that possesses a nutritional mutation that disrupts its ability to synthesize an essential biological molecule; cannot grow on minimal medium
