defunct mRNA translation in bacteria would... Correct Answer: prevent cells from replicating. lysogenic cycle Correct Answer: a viral reproductive cycle in which the viral DNA is added to the host cell's DNA and is copied along with the host cell's DNA Lytic phase or lytic cycle Correct Answer: phage replicates immediately, destroying the host cell (All phages carry out this life cycle) protein production Correct Answer: -proteins made at ribosomes -ribosomes on Rough ER make proteins that are excreted or attached to the cell membrane. The free ribosomes in the cytoplasm make proteins that stay in the cytoplasm. -new proteins produced at the rough ER are folded and processed ( chains are added) in the rough ER 2 -then they're transported to the Golgi apparatus in vesicles -at the Golgi apparatus the proteins undergo further processing ( chains are trimmed and more are added) -the proteins enter more vesicles to be transported around the cell proteins (found in mucus) move to the cell surface and are secreted. missense mutation Correct Answer: A base-pair substitution that results in a codon that codes for a different amino acid. nonsense mutation Correct Answer: A mutation that changes an amino acid codon to one of the three stop codons, resulting in a shorter and usually nonfunctional protein. frameshift mutation Correct Answer: mutation that involves the insertion or deletion of a nucleotide in the DNA sequence silent mutation Correct Answer: A mutation that changes a single nucleotide, but does not change the amino acid created.
