What is a deletion mutation?

Back

A deletion mutation is a type of genetic mutation where one or more nucleotides are removed from the DNA sequence, potentially leading to a frameshift in the reading frame.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are added or deleted from the DNA sequence, altering the reading frame of the genetic code.

Front

What is the primary goal of translation in biology?

Back

The primary goal of translation is to synthesize proteins from messenger RNA (mRNA) templates.

Front

How do enzymes affect chemical reactions?

Back

Enzymes increase the speed of chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is genetic material?

Back

Genetic material is the substance that carries genetic information in living organisms, primarily DNA or RNA.

Front

What are the main components of a virus?

Back

Viruses typically consist of genetic material (DNA or RNA) surrounded by a protein coat, and some may have an outer lipid envelope.

Front

What is the function of lipids in biological systems?

Back

Lipids serve as a source of energy, provide insulation, and make up cell membranes.

Front

What is the difference between bacteria and viruses?

Back

Bacteria are single-celled organisms that can live independently, while viruses are non-living entities that require a host cell to replicate.

Front

What is the role of ribosomal RNA (rRNA) in protein synthesis?

Back

Ribosomal RNA (rRNA) is a key component of ribosomes, which facilitate the translation of mRNA into proteins.

Front

What are the four main types of biomolecules?

Back

The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.
