Back

Transcription is the process of synthesizing a complementary RNA strand from a DNA template.

Front

What role do nitrogenous bases play in DNA?

Back

The order of the nitrogenous bases determines the order of amino acids in the synthesized proteins.

Front

What is the structure of DNA?

Back

DNA has a double helix structure composed of two strands of nucleotides.

Front

What is the function of RNA?

Back

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

Front

What is the difference between DNA replication and transcription?

Back

DNA replication copies the entire DNA molecule, while transcription only copies a specific segment into RNA.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.
