Answer:
Explanation:
Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.
During transcription, the code present in DNA gets transcribed into the code in mRNA. (messenger RNA)
RNA even though is a single stranded shows base pairing.
The pre-mRNA gets created from the DNA.
DNA has two strands, one of these strands acts as coding and another non coding strand.
The DNA shows base pairing with AGTC. [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]
Whereas mRNA base pairing with AGUC. [ U- Uracil ]
Here in mRNA, instead of thymine, uracil gets paired.
According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.
The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.
The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.

Answer:
keystone species
Explanation:
Keystone species are indispensable species that are essential to the maintaining of the balance of an ecosystem, and also play a major role in the way species in the ecosystem interrelate. The absence or removal of a keystone species from a habitat or ecosystem would lead to the disruption and imbalance of the ecosystem, and as such lead to the extinction of other species.
An example of a keystone species is the bee. Bees are very important in pollination of flowering plants and also ensure their survival. This plants serve as home to various insects that are source of food to birds. The removal of bees from this ecosystem would affect the ecological balance of this ecosystem.
