How is antibiotic resistance an adaptation?
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
When bacteria are not affected by antibiotics they have?
They have resistance to the antibiotic.
Who benefits from a mutation that causes antibiotic resistance in bacteria?
The bacteria benefits.
Antibiotic in gene cloning?
If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.
What is an example of direct evidence for evolution is... genetic changes in plants antibiotic resistance in bacteria pesticide resistance in insects or all of the above?
genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects.
Which biological agent may be susceptible to antibiotic's but can develope resistance?
bacteria
A mutation that causes antibiotic resistance in bacteria is a what mutation?
Missense mutation Nonsense mutation Frameshift insertion Frameshift deletion All may cause antibiotic resistance in bacteria
What is a word meaning a bacteria has adapted to antibiotics?
Resistant or resistance is when a bacteria has adapted to an antibiotic.
How does a population of bacteria resistant to antibiotics?
the bacteria mutates , so the antibiotic no longer affects the bacteria , therefore making it resistance
What contributes to the spread of antibiotic resistance among pathogenic bacteria?
Directional Selection
How antibiotics resistance occur?
Antibiotic resistance occurs when bacteria or other microbes builds the ability to resist the effects of the antibiotic. This happens when bacteria changes in a way that reduces or eliminates the effectiveness of the drugs designed to cure infections.
How do antibiotic resistant bacteria come about?
This term is misleading. The antibiotic "selects" bacteria that are not affected by it. If a person will grow bacteria on a petri dish and add an antibiotic to it, some bacteria may live and grow. This is actually a form of natural selection. The ones that will grow are resistance to the antibiotic. They have some way of not being affected. If a person takes a colony from the plate that has this resistance and grows it on another plate and add the antibiotic, all on the plate will be resistant.
