random bits test 3 Flashcards
Transformation
DNA released from one bacterium is taken up by another.
There are several copies of genes for each tRNA, a mutation in one copy will result in a percentage (say ~5%) of that specific tRNA that are mutated.
.
Transduction
When a virus acts as an unwitting agent of bacterial DNA transfer; the virus transfers a fragment of bacterial DNA from one cell to another.
Conjugation
Bacterial Sexy Time.
Conjugation, unlike transformation, requires cell-cell contact and the DNA (a copy) is passed across a bridge that forms temporarily between the pair of mating cells.
what interacts in complementation?
usually gene products like proteins
how many tRNAs for a codon “family”?
rules vary a bit, but generally one tRNA for any 2 codon family, such as AGU/C, and 2 different tRNAs for a 4 codon family, such as UCX (ser).
