LONG QUIZ - FINALS

What is the first step in protein synthesis?

• Mutation

• Translation

• Replication

• Transcription

Where does transcription occur in the cell?

• cytoplasm

• nucleus

• mitochondria

• endoplasmic reticulum

What is the role of mRNA processing in protein synthesis?

• mRNA processing ensures that the mRNA is ready for translation

• mRNA processing removes the 5' cap and 3' poly-A tail from the mRNA

• mRNA processing adds exons to the mRNA sequence

• mRNA processing involves converting DNA to RNA directly without any modifications

What is the function of ribosomes in translation?

• Ribosomes store genetic information

• Ribosomes regulate gene expression

• Ribosomes synthesize DNA

• Ribosomes translate mRNA into proteins.

How does tRNA contribute to protein synthesis?

• tRNA contributes to protein synthesis by regulating gene expression.

• tRNA contributes to protein synthesis by breaking down proteins.

• tRNA contributes to protein synthesis by storing amino acids in the cell.

• tRNA contributes to protein synthesis by delivering amino acids to the ribosome.

What is the primary component of nucleic acid?

• Proteins

• Nucleotides

• Carbohydrates

• Lipids

What is the main function of nucleic acid in protein synthesis?

• Provide genetic information for protein synthesis

• Store energy for protein synthesis

• Regulate the speed of protein synthesis

• Act as a catalyst in protein synthesis

Name the components of nucleic acid.

• Phosphate group, sugar molecule, amino acid

• Phosphate group, fatty acid, nitrogenous base

• Phosphate group, sugar molecule, nitrogenous base

• Hydrogen group, sugar molecule, nitrogenous base

Describe the role of RNA polymerase in transcription.

• RNA polymerase is not involved in the transcription process

• RNA polymerase breaks down DNA during transcription

• RNA polymerase catalyzes the synthesis of RNA from a DNA template during transcription.

• RNA polymerase synthesizes DNA from an RNA template

Explain the process of translation in protein synthesis.

• Translation is the process of converting DNA to RNA

• Translation occurs in the nucleus of the cell

• Translation involves the synthesis of DNA molecules

• Translation is the process where mRNA is decoded to build a protein in ribosomes
