What are all reasons why bacteria are useful in genetic engineering?
|
|
They are very small. They do not need large containers. They have no mitochondria.
|
|
|
They reproduce asexually. They can double their numbers in twenty minutes in goodconditions. They have cell walls.
|
|
|
They have the same genetic code as other organisms. They have plasmids. There is a lack of ethical concern about their use
|
|
|
Their DNA is not in a nucleus. They have a cell membrane. They have a large surface areato volume ratio

Explanation:
Detailed explanation-1: -Bacteria are cheap, easy to grow, clonal, multiply quickly, are relatively easy to transform, and can be stored at-80 °C almost indefinitely. Once a gene is isolated it can be stored inside the bacteria, providing an unlimited supply for research.
Detailed explanation-2: -Bacteria can translate foreign genes into proteins – and scientists have ways to ensure that the bacteria make the proteins in large amounts. For these reasons, bacteria can function as ‘protein factories’, producing medically important proteins and others.
