Missense mutation
Photosynthetic eukaryotic microbes are classified as _________.
algae

Enveloped, their host cell
During the ________ stage of the growth curve, the bacteria are growing at an exponential rate.
Log
___________ is responsible for translation in bacteria.
Ribosomes (50S and 30S in bacteria, 60S and 40S in eukaryotes)
_________ is an example of horizontal gene transfer.
Transformation, Transduction, Conjugation
_________ reproduction involves fusion of haploid cells to become diploid cells.
Sexual
Phages are inserted into the genome of the host during the _________ cycle.
lysogenic cycle
This type of media is used to inhibit the growth of organisms on a type of media while promoting the growth of others.
Selective media
When bacteria divide by ____________, they transfer an identical copy of their genome to their daughter cells. This is known as ______________.
Binary fission, vertical gene transfer
Transduction requires the use of ________ to transfer genetic material between non-related bacterial cells.
A bacteriophage
These eukaryotes are always unicellular and can be classified based on their motility
Protozoans (ciliates use cilia, flagellates use flagella, pseudopods use pseudopodia)
After entering the host cell _________ of animal viruses is needed to release the nucleic acids from the capsid.
Uncoating
__________ is appropriate for preparation of a patient's skin prior to a medical procedure.
Degerming
This is a method of genetic diversity that is not a form of horizontal gene transfer or point mutation.
