DNA, RNA and transcription BR

Front

What is the role of DNA in cells?

Back

DNA serves as the blueprint for making proteins, which are essential for the structure and function of cells.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What are the four nitrogenous bases in RNA?

Back

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

Front

What is transcription?

Back

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

Front

What enzyme is responsible for transcription?

Back

RNA polymerase.

Front

How do RNA bases pair with DNA bases during transcription?

Back

A pairs with U, and C pairs with G.

Front

What is the difference between DNA and RNA structure?

Back

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

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What is the function of DNA polymerase?

Back

DNA polymerase adds nucleotides to a growing DNA strand during DNA replication.

Front

What is the significance of the sequence of nitrogenous bases in DNA?

Back

The sequence determines the genetic information and instructions for building proteins.
