What is the function of DNA in living organisms?

• To synthesize proteins directly.

• To regulate metabolic pathways.

• The function of DNA in living organisms is to store and transmit genetic information.

• To provide energy for cellular processes.

How many chromosomes do humans have?

• 46

• 50

• 44

• 48

What is the process of DNA replication?

• DNA replication involves the breakdown of RNA molecules.

• DNA replication occurs only during cell division.

• DNA replication is the process by which a cell duplicates its DNA, resulting in two identical copies.

• DNA replication is the process of protein synthesis.

What role do genes play in DNA?

• Genes are segments of DNA that encode instructions for protein synthesis.

• Genes are the building blocks of cells.

• Genes are segments of RNA that regulate cell division.

• Genes are responsible for the color of DNA.

How does DNA differ between individuals?

• DNA differences are caused by environmental factors only.

• All individuals have the same number of chromosomes.

• DNA differs between individuals due to variations in nucleotide sequences.

• DNA is identical in all individuals.

What is the significance of the Human Genome Project?

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

• It had no impact on medical research.

• It focused solely on animal genetics.

• It was primarily a project for mapping plant genomes.

What techniques are used to analyze DNA?

• Chromatography

• Mass Spectrometry

• Nuclear Magnetic Resonance (NMR)

• Polymerase Chain Reaction (PCR), Gel Electrophoresis, DNA Sequencing, Restriction Fragment Length Polymorphism (RFLP)
