B
All organisms contain RNA
C
The most important genes are different among most people
D
No two people, except identical twins, have exactly the same DNA
Explanation: 

Detailed explanation-1: -It’s a misconception that twins have identical fingerprints. While identical twins share many physical characteristics, each person still has their own unique fingerprint.

Detailed explanation-2: -The finer details of the patterns of skin ridges are influenced by other factors during fetal development, including substances taken during pregnancy and the environment inside the womb. These developmental factors cause each person’s dermatoglyphs to be different from everyone else’s.

Detailed explanation-3: -DNA fingerprinting uses chemicals to separate strands of DNA and reveal the unique parts of your genome. The results show up as a pattern of stripes that can be matched against other samples.

Detailed explanation-4: -DNA fingerprinting is a technique used to identify individuals by making use of the unique DNA sequence patterns that exist in their genomes. It does not make use of physical fingerprints, unlike the name. Cells from a sample of blood, semen, hair strands etc. are commonly used in this technique.
