When a cell copies its DNA (replication), the original DNA ladder is broken apart and new nucleotides are added to the center. T
his creates two exact copies, each one made from half the original DNA molecule. • DNA polymerase (the enzyme which builds DNA) will only attach bases which match with the original strand of DNA.
• In DNA replication, Adenine and Thymine will bong together and Cytosine and Guanine will bond together.
• When creating the matching stand the following pairing rules must be used:
A? T
C? G
Directions: Use the base pairing rules above to figure out the sequence of the new strand of DNA for the original strands below.
Yes, I believe they are. If you are talking about us humans finding fossils then no. There are many fossils, bones and other interesting things still to be found
