Explanation: Bacteria can acquire resistance by getting a copy of a gene encoding an altered protein or an enzyme like beta lactamase from other bacteria, even from those of a different species. There are a number of ways to get a resistance gene:
1) During transformation - in this process, akin to bacterial sex, microbes can join together and transfer DNA to each other.
2) On a small, circular, extrachromosomal piece of DNA, called a plasmid - one plasmid can encode resistance to many different antibiotics.
3)Through a transposon - transposons are "jumping genes," small pieces of DNA that can hop from DNA molecule to DNA molecule. Once in a chromosome or plasmid, they can be integrated stably.
4)By scavenging DNA remnants from degraded, dead bacteria.
Unfortunately, if a bacterium gets a resistance gene stuck into its chromosomal DNA or picks one up in a free-floating plasmid, all of its progeny will inherit the gene and the resistance it confers. Why do resistance genes persist and spread throughout bacterial populations? It's basically just Darwin's idea of the survival of the fittest, reduced to a microscopic level -- bacteria with these genes survive and outgrow susceptible variants
Its false, that verified answer fooled me. I swear to god
Your answer is True.
A is your answer
Answer:
The colour of a mouses fir is determined by a single gene. different versions of a gene are known as alleles.
Explain how a gene codes for a characteristic?
From the assertion above, every genotype is made up of a pair of allele which one is donated from a parent to form a genotype. The dominant gene determines the characteristics that the offspring would exude.
Explanation:
if parent A donates an allele T and parent B donates an allele t, both parents now has Tt has a pair of allele but the ones from parent A dominates which is T over t, then such offspring exudes tallness which is a gene inherited from one of the parents
Answer: option c a green stem without bark
Explanation: herbecious plants are usually called non Woody plant. They hve green stem and they usually have underground root.that help them take up water and nutrients from deep in the soil. They are mostly grassess and ferns. Their stem is usually soft because its body contains cellulose that makes them to be flexible. They grow very fast and have a lot of seeds.
