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.
Sea ice has a greater impact on sea level rise than land ice. Sea ice is much more variable in volume and mass than land ice, which is relatively fixed. As a result, sea ice has a greater impact on sea level rise.
Autotrophs are organisms that are able to use a source of energy such as sunlight, to produce their own food. Heterotrophs cannot produce their own food and must rely on the foods they ingest for energy.
