How Does DNA Make Protein?

The video explains how DNA is central to protein synthesis, which is vital for cellular functions. Proteins, made of amino acids, are coded by DNA sequences. Each gene in DNA corresponds to a specific protein. The process involves transcribing DNA to RNA, which is then translated by ribosomes to form proteins. This mechanism is crucial for life and contributes to individual uniqueness.

What are proteins primarily composed of?

• Carbohydrates

• Nucleotides

• Fatty acids

• Amino acids

How many amino acids does human DNA code for?

• 10

• 20

• 30

• 40

What is a gene?

• A stretch of DNA coding for a protein

• A type of amino acid

• A sequence of RNA

• A protein molecule

What role does RNA play in protein synthesis?

• It forms the structure of ribosomes

• It transcribes DNA instructions and carries them to ribosomes

• It breaks down proteins

• It stores genetic information

What determines the unique nature of proteins in an organism?

• The DNA inherited

• The amount of RNA

• The number of ribosomes

• The sequence of amino acids
