DNA comprises the genetic makeup of every organism. It carries genetic information that is used by the organs in the body to determine what functions to carry out.


DNA cannot be used to see the nuclei of cells or absorb viruses. A person's personality cannot be determined from DNA.


The answer is D. to determine if people are related, as DNA between two people can be compared for similarities of code between the two.

During DNA Replication, a DNA strand that has the bases 3'ATACGC5' produces a strand with the bases
Gemiola [76]

During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'  

Answer: Option B

<u>Explanation:</u>

The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.

Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
