Transcription

Front

What is transcription?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

Which nitrogen base is not found in RNA?

Back

Thymine (T) is not found in RNA; instead, uracil (U) is used.

Front

What is the role of DNA in transcription?

Back

DNA serves as the blueprint for the production of RNA within a cell.

Front

List the five nitrogen bases found in nucleic acids.

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G), and Uracil (U).

Front

What determines the genetic code in DNA?

Back

The order (sequence) of the nitrogen bases determines the genetic code in DNA.

Front

What is the complementary RNA sequence for the DNA sequence 'GAT'?

Back

The complementary RNA sequence for 'GAT' is 'CUA'.

Front

What is the function of RNA?

Back

RNA plays a crucial role in translating the genetic information from DNA into proteins.

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 uracil instead of thymine, and has ribose sugar instead of deoxyribose.

Front

What is mRNA and its role in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.
