DNA Protein Synthesis Mitosis Meiosis

What is the function of DNA in the cell?

• DNA functions as a structural component of the cell membrane

• DNA acts as a neurotransmitter in cell communication

• DNA is responsible for energy production in the cell

• The function of DNA in the cell is to store genetic information and provide instructions for protein synthesis.

Explain the process of protein synthesis.

• The process of protein synthesis involves transcription, where DNA is copied into mRNA, and translation, where mRNA is read by ribosomes to assemble amino acids into proteins.

• Protein synthesis involves photosynthesis and cellular respiration.

• Protein synthesis is a process where lipids are converted into carbohydrates.

• Protein synthesis occurs in the mitochondria and Golgi apparatus.

Differentiate between mitosis and meiosis.

• Mitosis results in two daughter cells with the same number of chromosomes, while meiosis results in four daughter cells with half the number of chromosomes.

• Mitosis and meiosis both result in two daughter cells with half the number of chromosomes.

• Meiosis results in two daughter cells with the same number of chromosomes.

• Mitosis results in four daughter cells with half the number of chromosomes.

Describe the role of tRNA in protein synthesis.

• tRNA is responsible for DNA replication in cells

• tRNA functions as a structural component of the ribosome

• tRNA plays a crucial role in delivering amino acids to the ribosome for protein synthesis.

• tRNA acts as a catalyst in protein synthesis

How does meiosis differ from mitosis in terms of chromosome number?

• Meiosis results in cells with the same number of chromosomes as the original cell.

• Mitosis results in cells with half the number of chromosomes as the original cell.

• Meiosis results in cells with half the number of chromosomes as the original cell, while mitosis results in cells with the same number of chromosomes as the original cell.

• Meiosis results in cells with double the number of chromosomes as the original cell.

What is the significance of crossing over in meiosis?

• Crossing over promotes genetic diversity.

• Crossing over prevents genetic diversity.

• Crossing over occurs in mitosis instead of meiosis.

• Crossing over has no impact on genetic variation.

What is the purpose of DNA replication?

• To generate new genetic material for a different species.

• To create an identical copy of the genetic material for cell division.

• To prevent cell division from occurring.

• To decrease the amount of genetic material in a cell.
