Energy holds them together.
Answer:
For the object of to be considered alive , it must have DNA and all the characteristics of living things.
Explanation:
If one is to determine whether the object is alive or not the object should possess all the properties of living things. firstly, it should have the genetic material the DNA without which the cell can't be alive or the nucleus in case of PROKARYOTES. it should have the ability to reproduce, move , to grow and to excrete without which it would not be considered alive.
Bacteria can be SUSCEPTIBLE or RESISTANT to antibiotics. Susceptible bacteria can't grow if the drug (i.e., the antibiotic) is present.
Susceptibility to antibiotics occurs when bacterial colonies can't grow in presence of the antibiotic (e.g., erythromycin).
Some antibiotic-resistant bacteria include:
- Methicillin-resistant <em>Staphylococcus aureus</em> (it is one of the most common antibiotic-resistant bacteria)
- Vancomycin-resistant <em>Enterococcus</em>

The product of the lac z gene is an enzyme, this enzyme do in the bacterial cell that enzyme is known as β-galactosidase, that's an important a part of the metabolism of lactose.
<h3>What are lactose restriction enzyme ?</h3>
When a restriction enzyme along with BamHI is used to reduce the plasmid, it might reduce the circle at one place. The reduce could open up the circle withinside the LacZ gene. This is due to the fact gene cloners have located a bit of DNA that has many limit enzyme reducing in the LacZ gene.
It cleaves (separates) a disaccharide lactose molecule into a ways greater digestible glucose and galactose lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose.
