FAQs on Genes & Alleles Video Lecture - Biology A-Level - A Level
| 1. What are genes and alleles? |  |
Ans. Genes are segments of DNA that contain instructions for building proteins, which are essential for the functioning and development of living organisms. Alleles, on the other hand, are different forms of a gene that can exist at a specific location on a chromosome.
| 2. How do genes and alleles determine our traits? | |
Ans. Genes and alleles play a crucial role in determining our traits by controlling the production of proteins that influence various physical and biochemical characteristics. The combination of alleles inherited from our parents determines the specific traits we possess.
| 3. What is the relationship between genes and genetic disorders? | |
Ans. Genetic disorders are caused by abnormalities or mutations in genes. These mutations can alter the function of proteins or disrupt their production, leading to various health conditions or diseases. Some genetic disorders are inherited, while others can arise spontaneously.
| 4. Can genes and alleles change over time? | |
Ans. Yes, genes and alleles can change over time through a process called genetic variation. Mutations, which are changes in the DNA sequence, can introduce new alleles into a population. Additionally, genetic recombination during sexual reproduction can shuffle existing alleles, leading to different combinations in offspring.
| 5. How do scientists study genes and alleles? | |
Ans. Scientists study genes and alleles through various techniques, such as DNA sequencing and genetic mapping. These methods allow them to identify specific genes, determine the sequence of DNA bases, and analyze the distribution of alleles within populations. This research helps in understanding genetic diseases, evolutionary relationships, and the role of genes in different traits and characteristics.
