Answer:
5' AUGAAGUUUGGCUAA 3'
Explanation:
The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.
The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.
For the DNA sequence;
3' TACTTCAAACCGATT 5'
The mRNA sequence will be synthesized;
5' AUGAAGUUUGGCUAA 3'
There really isn't a specific answer to this question but it seems like the evolved around Africa
Answer:
With decrease in pH of ocean water, the survival rate of corals, algae, and fish in coral reef reduces.
Explanation:
Coral reefs find difficulty in living in acidic ocean water. It is so because the coral’s shell that is made up of calcium carbonate is unable to sustain in acidic environment.
Not only this the skeleton of snails, clams, algae , fish etc is also made up of calcium carbonate. Increased acidity leads to death of these species.
Thus, the lower is the pH of ocean water, the higher is its acidity and hence the lower is the probability of survival of corals, algae, and fish in the coral reef
