Back

Transcription

Front

Which cell organelle is the site of Translation to produce proteins?

Back

Ribosome

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of tRNA in translation?

Back

tRNA transports amino acids to the ribosome and matches them to the codons in mRNA.

Front

What is the difference between DNA and RNA in terms of structure?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is the process of converting mRNA into a protein called?

Back

Translation

Front

What are mutations and how can they affect protein synthesis?

Back

Mutations are changes in the DNA sequence that can lead to changes in the amino acid sequence of proteins, potentially altering their function.
