Sunflowers grow on a large stalk, and often only produce one flower. paddy plants produce many small flowers, with heavy pollen.
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
A biological system is a complex network of biologically relevant entities. ... Examples of biological systems at the macro scale are populations of organisms. On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the nervous system. source: google
