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 prote...

Describe the signals and mechanisms required for import into the peroxisome. - Answer -peroxisomal targeting sequence -peroxisomal import machinery (Pex5 receptor- first thing that binds on and recognizes signal sequence) Describe the functions of the SRP (signal recognition particle). - Answer -Recognizes hydrophobic amino acid sequence to stop translation, brings sequence to ER. -Binds to the ribosome with an ER signal sequence and stops translation of the protein, then docks the rib...

one gene-one enzyme hypothesis - each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? - Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) - Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials into amino acids and vitamins needed for gro...
