Airida [17]

Answer:

<h2>5'-UCAAUGC-3'</h2>

Explanation:

According to base pairing rule of DNA and RNA, A is always pairs with T ( in case of DNA) or with U ( in case of RNA) with two hydrogen bonds(A=T), and C is always pairs with G in both DNA and RNA  with three hydrogen bonds ( C≡G).

As given here, one segment of RNA molecule containing sequence 5'-GCAUUGA-3', so as the rule, G always binds with C and so on, so the sequence of the binding segment would be 3'-CGUAACU-5'. it can be written as 5'-UCAAUGC-3'

baherus [9]

Answer:

At least 17 PCR cycles or 16 PCR cycles

Explanation:

As we know -

In one chain of  heating and cooling  of polymerase chain reaction (PCR), the strands of DNA gets doubled.

The general mathematical representation of this is

{2^n - (2 *  n)}

where "n" is the number of PCR cycles.

It is given that DNA strands  to be produced is 16 times the original quantity of DNA.

So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less  than 16 times the original quantity of DNA
