7. I. What do you know about DNA/RNA?

8. II. What is DNA?
DNA is a long molecule, like a chain, where the links of the chain are pieces called nucleotides. (sometimes also called “bases.”)
DNA is basically a long molecule that contains coded instructions for the cells. DNA stands for deoxyribonucleic acid.
About half of our DNA comes from our mother, and half comes from our father. Which pieces we get is basically random, and each child gets a different subset of the parents’ DNA.

9. III. Structure of DNA:
Each DNA nucleotide is made up of the following:
Phosphate : (P)
Simple Sugar : DNA: deoxyribose (D), RNA: ribose (R).
Nitrogen Base : Four Types in DNA: adenine (A), guanine (G), thymine (T), cytosine (C). Four Types in RNA: all of them except thymine (uracil instead)
***Adenine and Thymine are always paired together.
***Cytosine and Guanine are always paired together.

10. IV. Shape of a DNA molecule:
The structure of DNA was determined by James Watson and Francis Crick.
They described the shape of a the DNA molecule as a double helix.
Double helix: two strands of DNA that are coiled around each other and attached by bonds between the nitrogenous bases of each chain.

11. V. What is RNA? RNA is a nucleic acid used to make proteins.
RNA stands for ribonucleic acid.

12. VI. RNA vs. DNA DNA RNA Double stranded single stranded
Sugar-deoxyribose sugar-ribose
Nitrogen base: thymine nitrogen base: uracil

13. VII. Types of RNA
Messenger RNA: brings instructions from DNA in the nucleus to the cell’s factory floor. (cytoplasm)
Ribosomal RNA: binds to the mRNA and uses instructions to assemble amino acids in the correct order.
Transfer RNA: delivers amino acids to ribosomes to be assembled into proteins.
