Transcription practice

Front

What is transcription?

Back

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

Front

What type of molecule is produced during transcription?

Back

Messenger RNA (mRNA) is produced during transcription.

Front

What does transcription convert DNA into?

Back

Transcription converts DNA into a single-stranded RNA molecule.

Front

What sugar is found in RNA?

Back

Ribose is the sugar found in RNA.

Front

What is the function of Messenger RNA (mRNA)?

Back

The function of mRNA is to carry the genetic message from DNA to the ribosome, where it is translated into a protein.

Front

Which base is not found in RNA?

Back

Thymine (T) is not found in RNA; instead, RNA contains Uracil (U).

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase is the enzyme that synthesizes RNA by unwinding the DNA and adding RNA nucleotides complementary to the DNA template.

Front

What are the three main types of RNA?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

How does RNA differ from DNA?

Back

RNA is single-stranded, contains ribose sugar, and has uracil instead of thymine, while DNA is double-stranded, contains deoxyribose sugar, and has thymine.

Front

What is the significance of the promoter region in transcription?

Back

The promoter region is a specific sequence of DNA that signals RNA polymerase where to begin transcription.
