Describe DNA Replication...

DNA can make exact copies of itself/self-replicate. When more DNA is needed by an organism(like during reproduction or cell growth) the hydrogen bonds between the nucleotide bases break and the 2 single strands of DNA seperate. New complementary bases(T-A & C-G) are brought in by the cell and paired with each of the 2 seperate strands, forming 2 new identical double-stranded DNA molecules. This is the Replication of DNA.

Compare & Contrast DNA & RNA...

Contrast

• DNA is double-stranded




• RNA is single-strandes




• DNA has Adenine(A), Thymine(T), Cytosine(C), & Guanine(G)




• RNA has (A), (C), (G), & Uracil(U)




• RNA is the main genetic material used in viruses




• Viruses dont have DNA

Compare

• Both are genetic material

Describe each component of the cell cycle...

The cell grows and duplicates its DNA and centrioles --> The chromatin condenses into chromosomes --> The chromosomes line up across the middle of the cell --> The sister chromatids separate into individual chromosomes and move apart--> The chromosomes gather at opposite ends of the cell --> The cell membrane pinches the cytoplasm in half--> Repeats
