Protein Synthesis 20-21

Front

What is the main function of tRNA?

Back

The main function of tRNA is to bring amino acids from the cytoplasm to the ribosomes.

Front

What is the correct order for protein synthesis?

Back

1. DNA is used to make a copy of mRNA. 2. mRNA leaves the nucleus and goes to the ribosome. 3. mRNA is translated to protein with the help of tRNA.

Front

What is the complementary RNA sequence for the DNA strand GTAGTCA?

Back

The complementary RNA sequence is CAUCAGU.

Front

Is the strand ATG CGG TAG from DNA or mRNA?

Back

The strand ATG CGG TAG is from DNA.

Front

What does mRNA make a copy of?

Back

mRNA makes a copy of one gene only at a time.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where mRNA is translated into proteins.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process of decoding mRNA to synthesize proteins.

Front

What is the structure of tRNA?

Back

tRNA has a cloverleaf structure with an anticodon on one end and an amino acid attachment site on the other.
