Protein Synthesis and Genetics Concepts

How is the human genome organized within the nucleus?

• As a single, long strand of DNA

• Into 23 pairs of chromosomes

• As a collection of free-floating genes

• Within ribosomes

Which enzyme is responsible for creating messenger RNA (mRNA) from a DNA template?

• DNA ligase

• RNA polymerase

• Helicase

• Ribosome

What occurs in Transcription?

• The synthesis of messenger RNA (mRNA) from a DNA template.
• The translation of mRNA into proteins.

Which of the following leaves the nucleus to carry the code for protein synthesis?

• DNA
• Ribosome RNA (rRNA)

• messenger RNA (mRNA)

What is the primary role of transfer RNA (tRNA) molecules during protein synthesis?

• To process messenger RNA in the nucleus

• To carry amino acids to the ribosome

• To unwind the DNA double helix

• To form the 3D structure of a protein

How many amino acids exist?

• 18
• 25
• 20

What occurs in Translation?

• mRNA is converted into DNA.
• In Translation, proteins are synthesized from mRNA.
• DNA is replicated into mRNA.

What is the central DOGMA of Protein Synthesis?

• RNA -> DNA -> Protein
• DNA -> RNA -> Protein
• DNA -> Protein -> RNA
