DNA Structure 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 are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a single-stranded molecule that plays a crucial role in the synthesis of proteins.

Front

What are the three types of RNA?

Back

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

Front

What is the function of mRNA?

Back

mRNA carries the genetic code from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus of the cell.

Front

Where does translation occur in the cell?

Back

Translation occurs in the cytoplasm at the ribosome.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
