Answer:
A DNA fragment is inserted into a plasmid.
The DNA fragment replicates during cell division.
The plasmid enters a host bacterial cell.
The plasmid becomes part of a host cell's chromosome.
A host cell produces a protein that it would not have produced naturally.
Explanation:
Recombinant DNA is the DNA molecules formed invitro or lab condition with the help of a plasmid, bacterial cell as host and a desirable gene or DNA fragment by the technique of genetic engineering or recombination. This is also known as molecular cloning.
The correct order of steps in the DNA recombination process are as follows:
The desired DNA fragment is inserted into a vector or plasmid.
The DNA fragment replicates during cell division.
The plasmid enters a cell of host bacterial
The plasmid becomes part of a host cell's chromosome.
A host cell produces a protein that it would not have produced naturally.
Answer:
See the answer below
Explanation:
The impacts of wiping out the mice can be classified into two - positive or negative.
The positive impact resulting from wiping out the mice would be felt in terms of reduced destruction to properties, transmission of pathogens, and constituting a nuisance to the environment.
The negative impact, however, will largely be felt on the existing food chains in the community. Organisms that serve as food for the mice will experience a boost in their population as a result of reduced predation while organisms whose source of food depends on the mice will see a decline in their own population as a result of inadequate food. <em>This might create a chain reaction that may lead to a major disruption to the food chains and the overall functioning of the ecosystem. </em>
Answer:
The gametophyte produces the haploid gametes
Explanation:
Ferns are a group of lower plants that also undergo the ALTERNATION OF GENERATIONS in their reproductive life cycle. The plant consists of the SPOROPHYTE and GAMETOPHYTE. The sporophyte is a diploid plant body that produces the haploid spores via meiosis. These spores are released on the sporangium and grow into a haploid GAMETOPHYTE.
The gametophyte produces the haploid GAMETES i.e. male gametophyte (antheridium) produces sperm while female gametophyte (archegonium) produces eggs, which undergo fertilization to produce a diploid zygote that develops into the sporophyte. The cycle begins again.
Answer:
the question is not correct
Explanation:

Answer:
Probably because they just need air to being able to live and have air going in and out like carbon dioxide and getting rid of used air.
