Strands are complementary to each other, strand contain Adenine, Thymine Gunine and cytosine the other strand will also have this just in a different pattern. They have an antiparallel structure, a complementary strand is needed in order for replication to occur, along with the help of many enzymes.
Explanation: Strands are complementary to each other, its mean that if one strand contain Adenine, Gunine and cytosine so on the other strand there will Thymine bond with Adenine, Cytosine with Gunanine and Gunanine with Cytosine. DNA molecules have an antiparallel structure - that is, the two strands of the helix run in ... Replication relies on complementary base pairing, that is the principle explained ... DNA replication occurs through the help of several enzymes.
Irreducible complexity (IC) involves the idea that certain biological systems cannot evolve by successive small modifications to pre-existing functional systems through natural selection.
A plane mirror always forms a virtual image (behind the mirror). The image and object are the same distance from a flat mirror, the image size is the same as the object size, and the image is upright.
