genes
| Question | Answer |
|---|---|
| How many pairs of chromosomes does humans have? | 23 pairs of chromosomes |
| What is chromatin? | It is the mixture of DNA and proteins that make up chromosomes |
| What are 3 parts of a DNA? | DNA is made up of 3 parts: Phosphate (It provides structural support to the molecule and is the backbone of the DNA), Sugar Deoxyribose (It is simple sugars that is key component in a DNA), and 4 Nitrogeneous bases |
| What are 4 Nitrogeneous bases? | The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C). |
| What is Codon? | It is when 3 nucleotide sequence in which the order of the nitrogenous bases makes up a certain amino acid and there are 20 amino acids. |
| What is Nucleotide? | It is a rung in the DNA which contains 2 of the Nitrogenous bases. |
| What is amino acid? | Amino acids are molecules that combine to form proteins |
| What is Gene? | It is a segment of DNA strand which controls certain traits of an individual. |
| What is Phenylketonuria? | It is a disease in which the body does not have an enzyme to digest the amino acids. |
| What is down Syndrome? | It is a disease when an embryo has an extra chromosome. |
| What is Huntington disease? | It is a disease that affects the nerve cells so that the person loses muscles control. |
| What is transgenic organism? | It is a genetically modified organisms whose genes are altered or genes from other species are inserted. |
| What is genetic engineering? | It is the process of combining genes (DNA) from one organism to another. |
| What is Mutations? | It is when the Codon sequence in the DNA strand change its order to was in. This creates an abnormality of the protein the codon makes which means the protein can not do its function properly. |
| What is Mutagens? | It is radiations or substances that causes the genes to mutate. eg. Drugs, and smoking. |
| What is cloning? | It is the process of creating identical genetics copies of an organism. It occurs in plants naturally eg. cuttings of an plant can grow a new plant when you root them. |
