Unit 5: Protein Synthesis - Modified

Front

What is the role of DNA in protein synthesis?

Back

DNA controls the production of proteins in the cell.

Front

What molecule is produced during transcription?

Back

mRNA (messenger RNA) is created during transcription.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when a nucleotide base is inserted or deleted, shifting the entire DNA sequence and changing the entire protein.

Front

Which nitrogen base is found in DNA but not in RNA?

Back

Thymine is present in DNA but not in RNA.

Front

What is the flow of genetic information?

Back

The flow of genetic information is DNA -> RNA -> Protein.

Front

What is the function of mRNA?

Back

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

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide is replaced by another, potentially altering the protein produced.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where mRNA is translated into proteins.

Front

What is tRNA and its function?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis.
