Biology Review Quizs

-Messenger RNA, a type of RNA that conveys genetic information from DNA to the ribosome.
-Transcribed from DNA

• mRNA

• tRNA

• rRNA

• sRNA

-identical copies of cells are made which contribute to the growth of an organism

-mechanism for the repair of injured or old cellular tissue

• Importance of Cell Cycle

• Role of Mitosis in Energy Production

• Function of Ribosomes in Protein Synthesis

• Significance of DNA Replication in Genetic Diversity

describes how certain proteins are manufactured according to a code found within the DNA; the mechanism by which certain genes are turned on, up, down, or off, resulting in variations in the amount of product they produce

• Gene expression

• Protein synthesis

• DNA replication

• Transcription regulation

• Controls and coordinates body functions

• Transmits signals between the brain and other organs

What system is responsible for these functions?

• Nervous System

• Circulatory System

• Digestive System

• Endocrine System

The process during meiosis in which the number of chromosomes is reduced by half.

• Chromosome reduction

• Chromosome duplication

• Chromosome segregation

• Chromosome replication

a loss of genetic variation in a population that is established by a small group of individuals.

• bottleneck effect

• founder effect

• genetic drift

• mutation

The diffusion of water only, not solute, from areas of high concentration to lower concentration

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion

During the phases of growth, the cell will check it is ready for the next stage. When checks fail, there is a disruption to the cell cycle.

• Cell Cycle Checkpoints

• Mitosis Stages

• Apoptosis Mechanism

• DNA Replication Process

anatomical similarities between animals during the early embryo stages

• developmental homology

• functional homology

• molecular homology

• structural homology

A nitrogenous base found in RNA, which pairs with adenine.

• Uracil

• Thymine

• Cytosine

• Guanine
