Answer:
A DNA molecule produced by combining DNA from different sources is known as recombinant DNA.
Explanation:
Recombinant DNA (rDNA) can be obtained by coupling DNA fragments from different sources, a process that is performed at the restriction site level and uses enzymes.
Once rDNA has been designed —cutting out fragments of DNA that are then reassembled— it must be brought to a specific location in the cells, to be copied and expressed, using means of transport called vectors.
<u>DNA recombination</u> is performed in biotechnology laboratories specialized in the manipulation of genetic material.
The other options are not correct because:
- <u><em>Mutant or mutated DNA</em></u><em> is a DNA molecule with an alteration of its nitrogenous base sequence
</em>
- <u><em>Hybrid DNA</em></u><em> is a variant of recombiant DNA, in which only two DNA molecules from different sources are used.
</em>
- <u><em>Polyploid</em></u><em> refers to cells containing the genome of different species.</em>
Viruses enter human body like an invader and uses the living cells to replicate causing infections in the cell or can damage it.
Explanation:
The attacks of viruses on the body of living organisms is compared with a ‘sneak attack’ as they invade the body and enters into a living cell to replicate themselves. This may cause damage or bring about changes in the cell causing sickness and infections.
They can hide themselves on our body attacking sneakily to harm the immune system to fight the infection. This stealth infection can result in fever, damaging immunity, disorder etc.
You should move this question to Mathematics instead. Or at least physics.
If the shopper decided on having to adopt the apple cider
and honey diet, the shopper should consider things like the source credibility,
in which the shopper should know whether this diet produces benefit, if It is
factual and it is something that will not produce any harmful effects.
The answer is
Left: meiosis
Right: cloning
