Gene Expression

Front

What is gene expression?

Back

The process by which information from a gene is used to synthesize a functional gene product, typically a protein.

Front

What are the two main stages of gene expression?

Back

Transcription and translation.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA.

Front

What is translation?

Back

The process of decoding mRNA to synthesize a protein.

Front

What is a codon?

Back

A sequence of three nucleotides in mRNA that specifies an amino acid.

Front

What is the role of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is a substitution mutation?

Back

A type of mutation where one nucleotide is replaced by another, potentially altering the amino acid sequence.

Front

What is the genetic code?

Back

The set of rules by which information encoded in genetic material is translated into proteins.
