Plzzzz help which of the following are correct about DNA fingerprinting
choose all correct answers
A. DNA fingerprint and actual fingerprints are the same***
B. They can determine paternity (who's the baby daddy?)
C. They can be used to identify organisms
D. DNA fingerprints show matches for identifying victims and crimes**
D is mostly correct.
A is mostly incorrect.
C is true if one has the entire genome, which at present, few species have been mapped.
B Slightly correct. Twins? what is true is it gives a probabality of paternity.
To determine which of the given options are correct about DNA fingerprinting, we can evaluate each option based on its accuracy.
A. DNA fingerprint and actual fingerprints are the same: This statement is incorrect. DNA fingerprinting refers to the process of analyzing specific regions of DNA to observe unique patterns, while actual fingerprints are impressions left by ridges and patterns on the skin's surface. Therefore, option A is incorrect.
B. They can determine paternity (who's the baby daddy?): This statement is correct. DNA fingerprinting is commonly used for determining paternity by comparing the DNA profiles of the alleged father, the child, and the mother. By analyzing the similarities and differences in specific DNA regions, scientists can establish biological relationships. Therefore, option B is correct.
C. They can be used to identify organisms: This statement is correct. DNA fingerprinting can be used to identify and differentiate various organisms, including humans, animals, and plants, by analyzing their unique DNA patterns. This technique is widely used in forensic science, research, and conservation efforts. Therefore, option C is correct.
D. DNA fingerprints show matches for identifying victims and crimes: This statement is correct. DNA fingerprinting is an important tool in forensic investigations. By comparing DNA evidence collected from crime scenes to the DNA profiles of suspects or DNA databases, investigators can identify potential matches for both victims and perpetrators. Therefore, option D is correct.
In conclusion, the correct options are B, C, and D.
