Biology Protein Synthesis Quiz

In the process of creating a new protein in a human cell, what is the first step where the DNA code is copied into mRNA?

• Translation

• Transcription

• Replication

• Mutation

Imagine a factory where workers assemble cars from parts. In a similar way, where does the assembly of amino acids into protein take place within a cell?

• In the nucleus

• Inside the mitochondria

• On the cell membrane

In the process of creating a protein, what is the role of transcription?

• To produce fats

• To replicate genetic material

• To transcribe DNA into mRNA

• To decompose proteins

In the process of creating a blueprint for protein synthesis, which molecule serves as the template?

• tRNA

• mRNA

• DNA

• rRNA

In the process of creating a new protein in a human cell, what is the role of translation?

• To produce DNA copies

• To synthesize proteins from mRNA

• To replicate the cell

• To modify lipids

During a biology class, students were asked to identify the correct model of DNA. Which of the following did they identify correctly?

In the process of making proteins in a cell, which type of RNA is responsible for bringing amino acids to the site of protein synthesis, the ribosome?

• mRNA

• tRNA

• rRNA

• DNA

In a cell's protein factory, which process is responsible for reading the mRNA blueprint to assemble amino acids into a protein?

• Transcription
