D1.2 Protein synthesis

Front

What is transcription?

Back

• The process of synthesizing RNA using a DNA template.

Front

What enzyme is responsible for transcription?

Back

• RNA polymerase.

Front

What is the function of RNA polymerase during transcription?

Back

• It binds to the DNA and synthesizes RNA by adding RNA nucleotides complementary to the DNA template strand.

Front

Where does transcription occur in eukaryotic cells?

Back

• In the nucleus.

Front

What direction does RNA polymerase synthesize RNA?

Back

• In the 5' to 3' direction.

Front

What are the base pairs in DNA and RNA?

Back

• In DNA: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). In RNA: adenine (A) pairs with uracil (U).

Front

What is the role of hydrogen bonding in transcription?

Back

• Hydrogen bonds between complementary bases help stabilize the DNA-RNA interaction during transcription.

Front

What base does adenine (A) pair with in RNA during transcription?

Back

• Uracil (U).

Front

What base does cytosine (C) pair with in RNA during transcription?

Back

• Guanine (G).

Front

What is the role of complementary base pairing in transcription?

Back

• It ensures that the RNA strand is complementary to the DNA template strand, allowing accurate RNA synthesis.
