Front

What is transposase?

Back

Transposase is a protein that facilitates the insertion and excision of transposable elements in DNA.

Front

What is a transposable element?

Back

Transposable elements, also known as 'jumping genes', are DNA sequences that can change their position within the genome.

Front

What role do transposons play in genetics?

Back

Transposons can cause mutations, contribute to genetic diversity, and play a role in the evolution of genomes.

Front

What is the function of a transcription factor?

Back

Transcription factors are proteins that help regulate the transcription of specific genes by binding to nearby DNA.

Front

What is a ribozyme?

Back

A ribozyme is a RNA molecule that can catalyze biochemical reactions, similar to the action of protein enzymes.

Front

Define gene expression.

Back

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

Front

What is the central dogma of molecular biology?

Back

The central dogma describes the flow of genetic information from DNA to RNA to protein.

Front

What is the role of RNA polymerase?

Back

RNA polymerase is an enzyme that synthesizes RNA from a DNA template during transcription.

Front

What are the main types of RNA?

Back

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

Front

What is the significance of mutations in genetics?

Back

Mutations can lead to genetic variation, which is essential for evolution, but can also cause genetic disorders.
