Molecular Genetics

Front

What is an inducer in molecular genetics?

Back

An inducer is a small molecule that binds to a repressor protein, making it inactive and allowing gene transcription to occur.

Front

What is the mRNA sequence transcribed from the DNA sequence CCTAGCT?

Back

The mRNA sequence will be GGAUCGA.

Front

What shape does the DNA molecule represent?

Back

The DNA molecule represents a Double Helix shape.

Front

Where does translation occur in a cell?

Back

Translation occurs in the cytoplasm.

Front

What is the role of a corepressor in gene regulation?

Back

A corepressor is a molecule that binds to a repressor protein, enhancing its ability to inhibit gene transcription.

Front

What is the function of a promoter in DNA?

Back

A promoter is a region of DNA that initiates transcription of a particular gene.

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.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What are ribosomes and their role in translation?

Back

Ribosomes are cellular structures that facilitate the translation of mRNA into proteins.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein function.
