DNA and Protein Synthesis

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It is composed of two strands that coil around each other to form a double helix.

Front

What is the function of RNA?

Back

RNA (Ribonucleic Acid) plays a crucial role in the synthesis of proteins by acting as a messenger between DNA and ribosomes.

Front

What are the three types of RNA?

Back

The three types of RNA are: 1) mRNA (messenger RNA), 2) tRNA (transfer RNA), and 3) rRNA (ribosomal RNA).

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA. It occurs in the nucleus of eukaryotic cells.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information carried by mRNA.

Front

Where does DNA replication occur?

Back

DNA replication occurs in the nucleus of eukaryotic cells.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides on tRNA that pairs with a complementary codon on mRNA during protein synthesis.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins.

Front

What is the difference between DNA and RNA?

Back

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