How are adenine and guanine alike and different

Answers

Answer 1

Answer: They both are constituents of DNA.
Adenine, cytosine, guanine and thymine are the glue that holds together the two sugar-phosphate strands which form the back-bone of DNA. The order in which these bases occur is what stores the information in DNA.

List the 3 basic steps of DNA replication?

Answers

The 3 basic steps of DNA replication are: initiation, elongation and termination.

What is DNA replication?

DNA replication is the process by which cells make copies of their genetic material. The process occurs in three main steps:

Initiation: This step involves the separation of the double helix structure of the DNA molecule, and the unwinding of the two strands at a specific point called the origin of replication.

Elongation: This step involves the building of new strands of DNA, which are complementary to the original strands. This is done by enzymes called DNA polymerases, which add nucleotides to the growing DNA chain. The new strands are created in the 5' to 3' direction, meaning that the polymerase adds nucleotides to the 3' end of the strand.

Termination: Once the entire length of the DNA molecule has been replicated, the replication process is complete. The two new DNA molecules, which are exact copies of the original, are then separated from each other.

Darwin observed that the finches on two diffrent island in the galapagos belong to.the same family but showed alot of variations in their break size and shape how can this vaction be justified

Answers

The island where not the same and definitely have different foods, terrain, vegetation, etc.

Depending on what on finch eats, it's beak needs to be adapted to that food. And it also depends on what other things it uses for if he needs to poke the ground or rocks in search of food for example.

Each finch has adapted to its environment.

Hope it helped,

Happy homework/ study/ exam!
