(4) Insert the diagram page 190 ( Section 11.2 ) to Show the link DNA → protein → Characteristic. Write a sentence to explain what this means.

This diagram basically explains that DNA are the basic building building blocks of a human and their characteristics. As you can see the DNA has the power of the production of the protein, basically how it will end up being like because of the instructions found in the gene. Finally the protein is the reasone for the human's characteristics, hence hair, ckin color etc. So DNA really controls how one will look and be like as they progress in the years.

(5) What is the DNA molecule made up of? DNA molecules are made out of alternating phosphate and sugar molecules which are linked together into a long chain. These chains are called nucleotides. there are rungs that come off of the sugar molecules, these are called bases. There are 4 kinds of bases, these bases link toghether making the nucleotide. Which makes up DNA.

(6) How many different nucleotide molecules are there? List these. DNA ) is made up of 4 different chemical called nucleotide bases or organic bases. They are: - Adenine  - Thymine  - Cytosine  - Guanine These are also known as A, T, C, and G.

These bases can only link in certain ways, and during that link they make up the nucleotide, which makes up DNA.

(7) Write a sentence to explain which bases always match up together. The bases are consisted of 4 bases; A, G, C and T. which are split into two groups. A, G are purines and C, T are pyrimidines.

Since there are 4 bases, bases go together two by two in a particular order. It is essential for the bases G and C (Guanine and Cytosine) to be together and A and T (Adenine and Thymine) bonded together as shown in the diagram below.

(8) What shape is the DNA molecule (2 special words)? Draw a quick sketch (labeled) to show this shape. Double Helix

(9) Find and insert at least one image or YouTube (or other) video to show the structure of DNA.
