The primary function of DNA is to store and transmit genetic information.

To regulate metabolic pathways.

To synthesize proteins directly.

To provide energy for cellular processes.

Genes only affect an organism's behavior.

Traits are solely determined by environmental factors.

Genes have no impact on physical characteristics.

Genes influence traits by encoding proteins that determine an organism's physical and biochemical characteristics.

Proteins are simple molecules that do not interact with other substances in the body.

Proteins are primarily used for energy storage in the body.

Proteins are essential macromolecules that perform a variety of functions in the body, including tissue building, enzyme activity, and immune response.

Proteins are only found in animal products and have no role in plants.

The central dogma of molecular biology is the process of DNA -> RNA -> Protein.

DNA -> Protein -> RNA

Protein -> RNA -> DNA

RNA -> DNA -> Protein

Ribose sugar and uracil bases

The main components of DNA's structure are nucleotides, which include a phosphate group, a sugar (deoxyribose), and nitrogenous bases (adenine, thymine, cytosine, guanine).

Amino acids and proteins

Carbohydrates and lipids

DNA replication is initiated by RNA polymerase.

DNA replication involves the removal of nucleotides from the template strand.

DNA replication occurs through unwinding of the double helix, template strand synthesis, and nucleotide addition by DNA polymerase.

DNA replication occurs only during cell division.

Genotype refers to the physical appearance; phenotype is the genetic makeup.

Genotype is the sum of environmental influences; phenotype is the inherited traits.

Genotype is the observable characteristics; phenotype is the underlying DNA.

Genotype is the genetic constitution; phenotype is the expressed traits.

Traits are randomly assigned to offspring without any genetic influence.

Traits are passed through environmental factors only.

Traits are inherited through learned behaviors from parents.

Traits are passed from parents to offspring through the inheritance of genes.

Mutations are always harmful and cannot lead to beneficial traits.

A mutation is a change in the environment that affects DNA.

A mutation is a type of protein that enhances traits.

A mutation is a change in the DNA sequence that can affect traits by altering protein production.

Chromosomes are involved in the digestion of food.

Chromosomes are responsible for producing energy in cells.

Chromosomes carry and organize genetic information in the form of DNA, playing a key role in heredity and the expression of traits.

Chromosomes help in the formation of muscle tissue.

Environmental factors have no impact on genetic traits.

Environmental factors can modify gene expression and influence the prevalence of certain genetic traits.

Genetic traits are solely determined by DNA without any influence from the environment.

Environmental factors can only harm genetic traits without modifying them.

The Human Genome Project significantly advanced our understanding of human genetics and paved the way for personalized medicine and genetic research.

It aimed to eliminate all genetic diseases in humans.

It was primarily a project for developing new pharmaceuticals.

It focused solely on mapping animal genomes.

Scientists use DNA to identify individuals involved in crimes by comparing DNA profiles from evidence to known samples.

Forensic scientists use DNA to determine the age of a crime scene.

Scientists use DNA to create new species in the lab.

DNA is used to predict the weather patterns.

Asthma caused by environmental factors

Common genetic disorders include cystic fibrosis, sickle cell anemia, Down syndrome, Huntington's disease, and hemophilia.

Diabetes due to poor diet

Alzheimer's disease linked to aging
