DNA sequencing TED ED

What is a genome?

• The sequence of letters that make up the name of an organism

• The collection of genes within the cells of an organism

• The code that cells use to behave

• The set of proteins present in an organism

What is DNA?

• A molecule that forms genes

• A protein that regulates cell growth

• A chemical compound that gives color to the eyes

• A type of cell present in the brain

What is the goal of genome sequencing?

• Study the structure of proteins in an organism

• Analyze the shape of organs in an organism

• Determine the color of the eyes of an organism

• Know the sequence of letters that make up a genome

What common method is used to increase the detected signal of each letter of DNA?

• Add more letters to the genome

• Remove repeated letters from the genome

• Change the color of the DNA letters

• Make thousands of copies of each piece of the genome

What do the special colored letters do in the genome sequencing process?

• Cause mutations in the DNA

• Bind to their opposite letter in the DNA

• Are removed from the genome

• Determine the size of the genome

What happens after taking photographs of each fragment of the genome in the sequencing process?

• What happens after taking pictures of each fragment of the genome in the sequencing process?

• The colors are read to determine the sequence of letters

• The colors are removed to obtain the sequence of letters

• The fragments are compared with other genomes

Why is it important to interpret the genes of the genome?

• To understand the differences between genomes and how they affect organisms

• To determine the eye color of an organism

• To identify the age of an organism

• To predict the behavior of an organism

What aspects can be affected by disparities between people's genomes?

• The amount of sleep, exercise, diet, and studies

• Body temperature, blood pressure, sugar level, and cholesterol

• Height, weight, age, and gender

• Appearance, tastes, behavior, and response to medications

What was the approximate cost of sequencing the first human genome?

• Ten million dollars

• Five hundred thousand dollars

• One hundred million dollars

• More than three billion dollars

What is the main function of genes in the genome?

• Determine how cells behave

• Regulate body temperature

• Produce energy for the organism

• Control blood pressure
