What does it mean that the genetic code is 'universal'?

Back

The genetic code is considered 'universal' because it is the same in almost all organisms, indicating a common evolutionary origin.

Front

How do genetic and environmental factors influence health?

Back

Genetic and environmental factors influence health by affecting disease risk and health outcomes, shaping both individual and public health.

Front

What are the major parts of the brain?

Back

The major parts of the brain are the cerebrum, cerebellum, and brainstem.

Front

When does DNA replication occur in the cell cycle?

Back

DNA replication occurs during the S phase of the cell cycle.

Front

What role do plasmids play in genetic engineering?

Back

Plasmids are used as vectors to transfer genes into organisms in genetic engineering.

Front

Define 'genetic engineering'.

Back

Genetic engineering is the manipulation of an organism's DNA to alter its characteristics.

Front

What is the function of the cerebrum?

Back

The cerebrum is responsible for higher brain functions, including thought, action, and sensory processing.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is significant because it is the stage where DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What are vectors in genetic engineering?

Back

Vectors are tools used to deliver genetic material into cells, commonly used in genetic engineering.

Front

Explain the term 'phenotype'.

Back

Phenotype refers to the observable physical and physiological traits of an organism, determined by its genotype and environment.
