Introduction to Translation & Proteins

The video tutorial explains the process of translation, the final step in gene expression, where DNA instructions are transcribed into mRNA and used by ribosomes to build proteins from amino acids. It highlights the significance of proteins in various biological functions, such as catalyzing reactions, building tissues, transporting oxygen, and more.

What is the role of messenger RNA in the translation process?

• It transports amino acids to ribosomes.

• It forms the structure of ribosomes.

• It catalyzes the formation of peptide bonds.

• It carries genetic information from DNA to ribosomes.

How are amino acids arranged in proteins?

• In a circular pattern

• In long chains linked end to end

• In a random assortment

• In a branched structure

Which of the following is NOT a function of proteins?

• Catalyzing metabolic reactions

• Building muscle tissue

• Storing genetic information

• Transporting oxygen in the bloodstream

What role do proteins play in the bloodstream?

• They replicate DNA.

• They transport oxygen.

• They produce energy.

• They store nutrients.

Which process is NOT directly associated with proteins?

• Transporting molecules inside cells

• Photosynthesis

• Responding to stimuli

• Making messenger RNA
