Answer 1

Answer:While base pairing, adenine (A) always pairs with thymine (T) in case of DNA while it pairs with uracil (U) in case of RNA. On the other hand, guanine always pairs with cytosine whether DNA or RNA.

In the given sequence of DNA; AGCTTCGA  

Pairs with U and G pairs with C and vice versa.

So the RNA sequence comes to be: UCGAAGCU.

So, the correct option is 'UCGAAGCU'.
