Bacteria Genetics Flashcards
Are bacteria dna is a haploid or diploid state
Haploid state (23)
What is bacteriophage
A bacteriophage is a virus that can infect bacteria
Two types of bacteriophage are
Virulent phage
And temperate phage
These phages are also called prophage
Virulent phage
Temperate phage
Lysogenic phage
Temperate phage
A bacteria that has a prophage in its chromosome is called a
Bacteriophage
Lysogenic
Virulent phage
Temperate phage
Lysogenic
Virulent phages act by
Injecting its dna template into the bacteria causing the rna of the bacteria to use its template to synthesize
Which result in more phages and the bacteria cannot hold much longer and burst
Temperate phage act by
Inserting its dna into the chromosome and remaining dormant until it is activated
Bacteria genetics change that requires cell to cell contact is called
Transformation
Transduction
Conjugation
Trasposon
Conjugation
The transfer of genetic information from one bacteria to another through the use of phage is called
Transformation
Transduction
Conjugation
Trasposon
Transduction
Bacteria genetics changes using exogenous free floating dna is called
Transformation
Transduction
Conjugation
Trasposon
Transformation
What are transposon
Trasnposons are dna fragments that can move from one position to another in a dna strand
They are gene strands with leg
Cell to cell conjugation can only be done through what organ
Sex pilus
Plasmids are
Circular genetics information that are outside of the bacteria gene
They are bacteria genes oo but they are not attached together to the main gene body
Just floating freely genes
Genes in bacteria that are easily transferable are called
Transposon
Plasmid
Lysogenes
Bacteriophage
Plasmid
Through accumulation of hereditary factor bacteria can cause eloving through
Natural selection
Bacterial chromosome exist as
Double stranded closed circular and naked dna
Also super coiled
The chromosome of bacteria is located at the
Nucleiod
The chromosome of bacteria is it
Diploid or haploid
Haploid
Plasmids are carrying gene for extra resistance called
R factor
Plasmid cells are easily transferable to bacteria cell by
Conjugation
Plasmids are capable of autonomous replication
True or false
True
Transposon are capable of autonomous replication
True or false
False
Induced mutation is usually due to
Mutagen
Spontaneous mutation is usually due to
Typing error of dna in dna replication
What year did Francis crock and James Watson propose the genetics law
1954
