A random mutation in one bacteria can result in this.
think of a huge population of bacteria. billions of bacteria. and only 5 or so have the resistance by a random chance (random mutation).
the antiobiotics will kill all of bacteria, except for the 5 with the resistance.
Then, only those 5 will reproduce. since they reproduce asexually, this resistance will be passed on to all of the daughter. Then, all of sudden, there are a lot of bacteria around that are resistant to the antibiotic...
it can also occur by conjugation, which is when a bacteria inserts its DNA into another bacteria. this can result in the second bacteria having the resistance too.
this is a very basic description of the process.

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.
Why does an antibiotic not work the same for all bacteria?
Bacteria also do evolve. If one bacteria is mutated, and survives an attack by antibiotic, he multiplies and forms more bacteria which are more resistant against antibiotic. As days of surviving antibiotics and multiplying eventually creates a bacteria which is resistant against it.
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.
