DNA Structure
1. Dna Stands for deoxyribonucleic acid a self replicating material present in nearly all living organisms as the main constituent of chromosomes. 2. Dna structure is made up of molecules called nucleotides. 1) a five carbon ribose sugar, 2) a phosphate molecule and 3) one of four nitrogenous bases: adenine, guanine, cytosine or uracil.
DNA Replication
Define- Dna replication is the process of making a copy of Dna and there should be two dna stands after you replicate.
Step 1: Enzymes called helicase separate the dna strands.
Step 2: Enzymes called Dna polymerases add complementary nucleotides found floating freely inside the nucleus to each of the original strands
Step 3: DNA Polymerases finish replicating the Dna and fall off.
Is Dna Replication semiconservative or Conservative? Semiconservative replication would produce two copies that each contained one of the original strands and one new strand. Conservative replication would leave the two original template DNA strands together in a double helix and would produce a copy composed of two new strands containing all of the new DNA base pairs.
Where is DNA found in a cell ? Nearly every cell in a person's body has the sameDNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNAcan also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
