Dna Replication

DNA Replication What is DNA? DNA is a nuclei acid. Nucleic acids are made of nucleotides (ribose/deoxyribose, phosphate group and nitrogenous bases). DNA has deoxyribose, is stable, and has the bases adenine, guanine, thymine and cytosine; it determines genetic information. DNA looks like ATP. What is a DNA monomer? A DNA monomer is a nucleotide. A nucleotide is formed of a 5 Carbon sugar, a phosphate and a nitrogenous base (adenine, thymine, cytosine and guanine). The bases that make up...

Dna Replication

Dna replication is the biological process that happens to occur in all organisms and it copies thier DNA, it’s the basic process for biological inheritance. This process all begins when one double helix DNA molecule produces two exact identical copies of the molecule. Then the cell cycle begins, consisting of interphase, prophase, metaphase, anaphase and telophase. Each original strand of the double helix serves as an template for the production of the complementary strand. DNA replication begins...
