⩥ Horizontal gene transfer refers to the transfer of genes from one
organism to another, as occurs during conjugation between bacteria.
How does this differ from vertical gene transfer?.
Answer: In horizontal gene transfer, genes are transferred from one
mature adult organism to another. In vertical gene transfer, genes are
transferred from adults to offspring.
⩥ Horizontal gene flow is accomplished in prokaryotes by
____________..
Answer: Conjugation, transduction, and transformation
⩥ What was the LUCA?.
Answer: the last organism prior to the divergence of bacteria and
archaea
,⩥ Photosynthetic organisms were present when Earth was primarily
anoxic. Why was the appearance of cyanobacteria critical for the
oxidation of the atmosphere?.
Answer: The early forms of photosynthesis did not produce oxygen as a
waste product.
⩥ Which statements describe the evidence that supports the
endosymbiotic theory?.
Answer: Chloroplasts and mitochondria have a double-stranded, circular
piece of DNA in their cytoplasm
⩥ The genes for 16S rRNA are used to determine genetic relatedness
amongst microbes because __________..
Answer: these highly conserved genes are of adequate length to show
deep relationships
⩥ For organisms to be considered members of the same species, they
must ______________ ..
Answer: Be genetically and phenotypically cohesive
⩥ Some organisms seem to change names, for example VIbrio fischerii
is now Aliivibrio fischerii. How can it be known which is the proper
name..
Answer: The official source is the International Journal of Systematic
and Evolutionary Microbiology.
, ⩥ An organism of the genus Staphylococcus is _________, while an
organism of the genus Spirochaeta is __________________..
Answer: Spherical/Coiled
⩥ What is the biological function of endospores?.
Answer: They enable organisms to endure extremes of temperature,
drying and nutrient depletion
⩥ The cytoplasmic membrane could best be described as.
Answer: A highly selective permeability barrier
⩥ What makes phospholipid membranes good at keeping some
molecules out, and allowing others to freely pass..
Answer: They have both hydrophilic and hydrophobic regions
⩥ Integral proteins are mostly involved in _______________..
Answer: Transport function
⩥ How does water enter and exit a cell?.
Answer: By simple diffusion or by use of an integral transport protein
⩥ A glycoprotein is ______________..
