Why is uncoating not part of the bacteriophage life cycle?
Uncoating is not part of the bacteriophage life cycle because bacteriophages do not have an external capsid that needs to be removed to release their genetic material. Instead, bacteriophages inject their genetic material directly into a host bacterial cell.
Circular DNA molecule that is not part of the chromosome in bacterial cells?
The circular DNA molecule that is not part of the bacterial chromosome is called a plasmid. Plasmids are small, extrachromosomal pieces of DNA that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.
What happends when a bacteriophage infects a bacterial cell?
The phage injects it's genetic material into the bacteria this can either be RNA, DNA or both. This genetic material is then translated into viral proteins which are assembled into new viruses along with a brand new genetic package ready to infect a new bacteria.
What happens first when a phage infects a bacterial cell and is going to enter a lysogenic cycle?
it becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and kill the host cell
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
A bacteriophage is necessary for toxin production in?
A bacteriophage is necessary for toxin production in certain types of bacteria. This occurs when the bacteriophage infects the bacterial cell and inserts its genetic material, which can include genes encoding toxins. The bacterial cell then produces the toxin as part of the infection process.
When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage

What broken part of a chromosome becomes attached to a nonhomologous chromosome with no molecular loss?
A broken part of a chromosome that becomes attached to a nonhomologous chromosome without molecular loss is known as a translocation. This can lead to genetic disorders if the translocated segment disrupts the function of important genes located on the chromosome.

Which part of bacteriophage contain the DNA?
Head region
What is it called when a virus hides for a while as part of bacterial chromosome?
This process is known as lysogeny, where a virus integrates its genetic material into the chromosome of its host bacterium and remains dormant until conditions are favorable for reactivation.
How can bacterium produce restriction enzymes that do not cleave it's DNA?
Restriction enzymes cleave DNA at a particular recognition site -- a particular sequence of nucleotides. You can imagine the following scenarios:1. The bacterial chromosome does not contain the recognition sequence2. The bacterial chromosome contains the recognition sequence, but that particular part of the DNA is either supercoiled to keep the restriction enzyme from finding the sequence, or it's single stranded as when being replicated or transcribed.3. The bacterial chromosome contains the recognition sequence, but that particular part of the DNA is methylated or modified in some other way which prevents the restriction enzyme from attaching.
Region in bacteria where chromosomes are located?
The chromosome in bacteria is typically found in the nucleoid region, which is the central part of the cell where the genetic material is concentrated. The nucleoid is not surrounded by a membrane like the nucleus in eukaryotic cells, but it still serves as the central location for the bacterial chromosome.
What are difference between macrophage and bacteriophage?
bacteriophage is a virus that kills bacteria
