DNA, RNA 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 RNA?

Back

RNA (Ribonucleic Acid) is a single-stranded molecule that plays a crucial role in the synthesis of proteins. It is involved in translating the genetic information from DNA into proteins.

Front

What is protein synthesis?

Back

Protein synthesis is the process by which cells generate new proteins. It involves two main steps: transcription (copying DNA to mRNA) and translation (reading mRNA to assemble amino acids into proteins).

Front

What are the four bases of DNA?

Back

The four bases of DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What are the four bases of RNA?

Back

The four bases of RNA are Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

Front

What is an anti-codon?

Back

An anti-codon is a sequence of three nucleotides in tRNA that is complementary to a codon in mRNA, allowing for the correct amino acid to be added during protein synthesis.

Front

How does DNA replicate?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself. It involves unwinding the double helix and using each strand as a template to synthesize a new complementary strand.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs. They read the mRNA sequence and facilitate the assembly of amino acids into a polypeptide chain.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA. It occurs in the nucleus and is the first step in protein synthesis.
