1. Cell starts into mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)
3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)
4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)
5. Two new molecules of DNA are created
Statements:
Adenine
Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)
DNA
Replication
Double helix
3. golgi apparatus
2. rough endoplasmic
1. cytoplasm

Answer:
The negative effects of the destruction on the global environment as well as on the local environment are the following :
1) If forests are destroyed for making commercial area, the habitat of animals are also destroyed.
2) Forest helps in the cleaning of environment by consuming carbondioxide and releasing oxygen. If destruction of forest occurs, the environment remains polluted.
Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
