Answer:
No it would not be useful for cell.
Explanation:
RNA polymerase uses only one strand of DNA which is called the template strand for the synthesis of mRNA. The other strand which is not used to make mRNA is called the coding strand.
If an RNA polymerase is designed which transcribe both the strand than two different strands of mRNA will be generated that will have different nucleotide sequences and will code for different proteins. So one strands will generate a protein which have different amino acids sequence that will complicate the overall process for the cell.
Another problem is if two RNA strands are formed then they can form a double helix and the ribosome might not be able to bind on them and translation might stop. Therefore it would not be useful for cell.
Pyroxene and plagioclases feldspar
Answer:
The correct answer would be C) It increases survival for cuckoos, but decreases survival of the other birds.
The host chicks often face lots of competition from the cuckoo chicks in terms of food as well as space. It makes it difficult for the host chicks to survive.
It has also been found that cuckoo chicks beg to be fed more intensely due to which host chick die due to starvation.
In addition, in some species of cuckoo, cuckoo chicks remove host eggs from the nest within few days of hatching.
