Polymerase chain reaction is a method of preparing DNA for forensic analysis .
<u>Explanation:</u>
- In order to prepare DNA for the forensic analysis, it must be replicated in an amount that is easily detectable in any biomedical instrument for the analysis.
- This polymerase chain reaction is a process that is helpful in preparing the DNA in huge amounts by amplifying it.
- The mitochondrial DNA and nuclear DNA are the two types of DNA used in the forensic analysis.
Answer:
65
Explanation:
The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.
Total guanine + cytosine bases in the segment= 95 + 95 = 190
So, a total of adenine and thymine bases in the DNA segment= 320-190 = 130
Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be= 130/2= 65
