• Thymine

• Cytosine

• Uracil

During a biology class, Olivia is explaining the process of copying DNA to mRNA. What is this process known as?

• Translation

• Transcription

• Replication

• Methylation

During a biology class, Maya asked, "What molecule carries amino acids to the ribosome during protein synthesis?"

• mRNA

• tRNA

• rRNA

• DNA

Maya is studying biology and wants to know which type of RNA is a component of ribosomes. Can you help her?

• mRNA

• tRNA

• rRNA

• sRNA

During a biology class, Olivia is learning about transcription. What is the role of RNA polymerase in this process?

• Unwinding the DNA double helix

• Synthesizing RNA from a DNA template

• Transporting amino acids

• Binding amino acids together

During a biology class, Phoebe and Olivia are discussing which process involves the conversion of mRNA into a polypeptide chain. Can you help them identify the correct process?
