Click here to view an animation on DNA replication. 1. Why does DNA need to duplicate?
1. DNA needs to duplicate because the products of mitosis are two identical daughter cells. To make sure each daughter cell had the same amount of DNA as the mother cell, the DNA duplicates so each cell receives one copy.
ReplyDelete2. DNA duplicates during the "in between" phase of mitosis: interphase. Interphase is when the cell prepares for cell division.
3. DNA is made of nucleotides. The building blocks of nucleic acids are nucleotides, and DNA and RNA are the two main nucleic acids.
4. The four nitrogen bases present in DNA are: adenine, cytosine, guanine, and thymine.
When I clicked on it, the animation wouldn't load. :(
ReplyDeletethe four nitrogen bases in DNA are thymine, guanine, adenine and cytosine and DNA is made of nucleotides!

I tried a couple times, and it loaded!
ReplyDelete1. Why does DNA need to duplicate?
DNA needs to duplicate to ensure that the daughter cells in mitosis are identical to the mother cell and, therefore have the same number of chromosomes.
2. When does DNA duplicate?
DNA duplicates during Interphase, the longest stage of the cell cycle, although chromosomes cannot actually be seen until Prophase.
3. What is DNA made of?
DNA is made of building blocks known as nucleotides, just like proteins are made of amino acids, or carbohydrates are made of simple sugars.
4. What are the four nitrogen bases present in DNA?
The four nitrogen bases present in DNA are cytosine, adenine, guanine, and thymine.
1.Why does DNA need to duplicate?
ReplyDeleteIt needs to duplicate so that the daughter cells produced in mitosis have the same exact number of chromosomes as the mother.
2.When does DNA duplicate?
It duplicates during interphase.
3.What is DNA made of?
4. What are the 4 nitrogen bases present in DNA?
Adenine, Guanine, Thymine, and Cytosine.
1. Why does DNA need to duplicate?
ReplyDeleteWhen a cell divides, the new cells produced must have a full set of genes in order to function correctly.
2. When does DNA duplicate?
During Interphase.
3. What is DNA made of?
Nucleotides that are strung together in a row.
4. What are the four nitrogen bases present in DNA?
Adenine, Thymine, Guanine, and Cytosine!!!!!
I finally commented Ms.Alonso.

Great site. Presents things in a very easily understood format.
