CCP Biology DNA, Replication and Protein Synthesis

Front

What is the location of the promoter in DNA transcription?

Back

The promoter is located upstream from the template strand.

Front

Who is known for taking the famous X-ray diffraction photo of DNA?

Back

Rosalind Franklin.

Front

What is a frameshift mutation?

Back

A frameshift mutation is a genetic mutation caused by the insertion or deletion of a base in the DNA sequence.

Front

What is the role of the release factor in translation?

Back

The release factor binds to the stop codon in the A site in place of a tRNA.

Front

What is the corresponding codon for AGT during transcription?

Back

The corresponding codon is UCA.

Front

Define transcription in the context of DNA.

Back

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

Front

What is the function of RNA polymerase during transcription?

Back

RNA polymerase synthesizes RNA by adding nucleotides complementary to the DNA template strand.

Front

What are the three main stages of protein synthesis?

Back

The three main stages of protein synthesis are transcription, translation, and post-translational modification.

Front

What is the significance of the start codon in translation?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What is the difference between DNA and RNA?

Back

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