Cards

Term
Genetic variability in Eukaryotes
Definition
Sex accomplishes reproduction and recombination
Term
Genetic Variability in Bacteria
Definition

Seperate the process

 

-reproduction (binary fission)= verticle gene transfer

-recombination (or new combinations of genes in existing cells)= horizontal gene transfer

Term
Underlying givens of how bacterial genomes are different from our own
Definition

Foreign DNA recieved will always replace existing DNA.

 

Old DNA will be recycled

 

Plasmids move freely: to join and leave both the genome and other plasmids

 

"sticky ends" on plasmids take genes along

Term
Transformation
Definition

Donor cell must be dead

 

Recipient cell must be: same species, absorbs DNA

 

Replacement/recycling of homologous DNA

Term
Generalized Transduction
Definition

Lytic viral life cycle

 

Mistake during the assembly stage of viral life cycle

 

Random Genes are gained by fragments of host 1 DNA injected into host 2 DNA

Term
Specialized transduction
Definition

Lysogenic viral life cycle involved

 

Mistake is made during the synthesis stage of viral life cycal

 

Specific genes on host 1 genome

 

flanking insertion point of viral genes injected into host 2

Term
Bacterial Conjugation
Definition
is the transfer of genetic material between bacteria through direct cell-to-cell contact, or through a bridge-like connection between the two cells
