TED-Ed: Where do genes come from? - Carl Zimmer

The video explores the origin and evolution of genes, starting from primitive microbes to the diverse genes present today. It explains how gene duplication and mutations lead to new functions and how non-coding DNA can give rise to new genes. Examples include the evolution of genes for odor detection in humans and venom production in snakes. The process of gene diversification is ongoing, contributing to the adaptability and survival of species.

What is the primary role of genes in living organisms?

• To regulate body temperature

• To eliminate waste from the body

• To encode molecules that make up the body

• To provide energy for cellular processes

How do new genes typically arise according to the video?

• Through deliberate genetic engineering

• Through the fusion of different species

• By copying existing genes and accumulating mutations

• By spontaneous generation from non-living matter

What is an example of a mutation's effect on gene function mentioned in the video?

• A gene causing the organism to change color

• A gene making a protein in a different organ

• A gene becoming inactive

• A gene producing more energy

What is the significance of non-coding DNA in gene evolution?

• It is responsible for energy production

• It always remains non-functional

• It can mutate to form new functional genes

• It regulates the body's temperature

How do scientists view the future of gene creation on Earth?

• Gene creation is only possible in laboratories

• New genes will continue to form as long as life exists

• Gene creation has stopped

• All possible genes have already been formed
