Usually they transform them by changing their genetic code, they change it by splitting the genetics of a bacteria (it looks like a circle, rather than a double helix) and adding in a part of another organism's code, this is most commonly seen in preparing insulin for diabetics, the gene that codes for insulin is "spliced" onto the regular bacteria gene, and then the bacteria is grown, harvested, and refined to get insulin that would otherwise have to have come from pigs or other animals
What else can I help you with?
What modern organisms do scientists think the first cells resembled?
Bacteria were the first cells.
What are the two ways scientists transform plant cells without using plasmids?
Scientists can transform plant cells by using Agrobacterium tumefaciens, a bacterium that naturally transfers its DNA into plant cells, or by using gene guns to deliver DNA-coated particles into plant cells using a high-pressure gun.
How do scientists think mitochondria originated?
Scientists believe that mitochondria originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. Over time, the relationship between the host cell and the engulfed bacteria became mutually beneficial, leading to the evolution of mitochondria as specialized organelles responsible for energy production in eukaryotic cells.
What does the sex pillus of cells do?
The sex pilus is a filamentous structure on the surface of bacterial cells that is involved in the process of conjugation, which is a means of horizontal gene transfer between bacterial cells. It serves as a bridge through which the transfer of genetic material, such as plasmids, can occur between donor and recipient bacterial cells.
How do scientists use bacterial shapes and configurations to identify bacterial cells?
Scientists use bacterial shapes and configurations as key characteristics for identifying bacterial cells. For example, cocci are spherical, bacilli are rod-shaped, and spirilla are spiral-shaped. Observing these shapes under a microscope allows scientists to classify and identify different types of bacteria.
What are two ways scientists transform plant cells without using plasmids?
hello.

What factors might influence transformation efficiency?
Temperature, Pressure, Technique used to Tranform Bacteria, Time taken to Transform Bacteria, Concentration and Mass of Plasmid be used to transform the bacteria.
Is the following true or false for years many scientists thought that it was clone bacteria?
False. For many years, scientists were able to clone bacteria, but it was not a widespread belief that bacteria itself was cloned. Instead, bacteria can reproduce through a process called binary fission, where a single cell divides into two identical daughter cells.
How do scientists transform bacteria?
Usually they transform them by changing their genetic code, they change it by splitting the genetics of a bacteria (it looks like a circle, rather than a double helix) and adding in a part of another organism's code, this is most commonly seen in preparing insulin for diabetics, the gene that codes for insulin is "spliced" onto the regular bacteria gene, and then the bacteria is grown, harvested, and refined to get insulin that would otherwise have to have come from pigs or other animals
What did scientists discover with the help microscopes?
Scientists discovered the existence of cells, microorganisms, and structures within cells, such as organelles like mitochondria and chloroplasts. Microscopes have also helped researchers study complex biological processes at the cellular and molecular levels.
Membrane-bound organelles that transform energy in all eukaryotic cells?
Mitochondria are membrane-bound organelles that transform energy in all eukaryotic cells. They carry out cellular respiration to produce ATP, the main energy currency of the cell. Mitochondria have their own DNA and are thought to have originated from ancient symbiotic bacteria.
How do scientists think mitochondria originated?
Scientists believe that mitochondria originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. Over time, the relationship between the host cell and the engulfed bacteria became mutually beneficial, leading to the evolution of mitochondria as specialized organelles responsible for energy production in eukaryotic cells.
How are fungus cells difforent from bacteria cells?
Fungus cells are eukariyotic cells. Bacteria have prokariyotic cells
Do bacteria cells have nucleas?
Bacteria cells don't have a nucleas.
How are bacteria cells different then cells of prokayotes?
Bacteria are prokaryotes.
