Gene Expression (Protein Synthesis)

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

What are the two main processes of gene expression?

Back

The two main processes are transcription and translation.

Front

Where does transcription occur in a cell?

Back

Transcription occurs in the nucleus.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is translation?

Back

Translation is the process of synthesizing proteins from the mRNA template.

Front

What are ribosomes made of?

Back

Ribosomes are made of ribosomal RNA (rRNA) and proteins.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis.

Front

What is an amino acid?

Back

Amino acids are the building blocks of proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the start codon for translation?

Back

The start codon for translation is AUG, which codes for the amino acid methionine.
