DNA and RNA
| Question | Answer |
|---|---|
| What does DNA stand for? | Deoxyribonucleic Acid |
| DNA is a: | Nucleic Acid |
| Where is DNA found? | In the nucleus of cells |
| Chargaff's rule | The amount of one base is equal to the base pair on the complementary side |
| Eukaryotic DNA | The DNA is linear and tightly coiled in the nucleus chromosone. |
| Prokaryotic DNA | Shaped circularly and floats around in the cytoplasm |
| DNA is made up of individual units called: | Nucleotide |
| What are nucleotides made of: | One sugar, phosphate, and a nitrogen base |
| Base Pair rules | Adenine only pairs with Thymine Guanine only pairs with Cytosine |
| What are the 4 nitrogen bases? | Adenine, Thymine,Guanine, and Cytosine |
| Purines | Adenine and Guanine |
| Pyrimidines | Thymine and Cytosine |
| What's the difference between purines and pyrimidines? | Purines are double rings and are bigger then pyrimidine Pyrimidines is single ringed and are smaller then purines |
| True or false: Purines only bond with pyrimidines and vice versa | True |
| DNA's shape is described as: | A double helix |
| Watson and Crick | Using the knowledge of DNA at the time, they built a model of the structure of DNA by piecing together information and completed their study by using Roselind Franklind's "Photo 51" to prove DNA is a double helix |
| Rosalind Franklin | Rosalind Franklin extracted DNA and blast it with x-ray crystallography to take a photo of DNA's structure called "Photo 51" |
| How many Hydrogen bonds do Adenine and Thymine have? | 2 bonds |
| How many Hydrogen bonds do Guanine and Cytosine have? | 3 bonds |
| What is the function of DNA? | DNA holds genetic information or instructions that tell the cell what to do and what proteins to make |
| What's the relationship between DNA and amino acids? | The code that DNA has tells the cells what amino acids to make as proteins are made of amino acids |
| DNA are coiled into: | Chromosomes |
| Proteins called------and--------help to keep the DNA------- | 1.Histomes 2.Nucleosomes 3.Coiled |
| What is the backbone of DNA made up of? | Sugar and phosphates |
| What's the Sugar in DNA? | Deoxyribose |
| What's the sugar in RNA? | Ribose |
| What is a nucleotide? | The fundamental structural building blocks of nucleic acids like DNA or RNA |
