General Biology 2 Formative Assessment BNHS-SHS

Scientists discovered that a specific fragment of the organisms’ DNA is responsible in coding for its specific trait such as hair/skin/fur color. What is this fragment called?

• Chromosome

• Deoxyribonucleic acid

• Genes

• RNA

Which of the following enzymes enzyme which is vital in the process of genetic engineering because it splits or cuts the DNA to obtain the targeted gene?

• Activation enzyme

• Ligase 18

• Restriction enzyme

• Scissor enzyme

The process of changing or altering the genes may be summarized in four basic steps, which among the following steps come first?

• Isolate the DNA from the cell and identify the target part of the DNA

• Cut the specific part of the DNA through a special enzyme

• Combine the DNA from two different sources

• Introduce the new formed DNA to the host cell

The new DNA produced through genetic engineering will be introduced to a host cell to see how it will code for a new protein. What concept in biology is highlighted in this step?

• Law of inheritance

• . Law of conservation of energy

• Central Atom of Molecules

• Central Dogma of Molecular Biology

Which among the following best describes the Cenozoic era?

• Age of bacterium

• Age of invertebrates

• Age of reptiles

• Age of mammals

How will you describe the Geologic Time Scale?

• It divides up the history of the earth based on life-forms that have existed during specific times since the creation of the planet.

• It sums up the history of the earth based on life-forms that have existed during specific times since the creation of the solar system.

• It sectioned the history of the earth based on non-living things that have existed during specific times since the creation of the planet.

• It divides up the history of the earth based on spheres of the Earth where life-forms have existed during specific times since the creation of the planet.

The following are the principles of used in relative dating of fossils EXCEPT:

• Law of Superposition

• Law of Original Horizontality

• Law of Cross-Cutting Relationship

• Law of Superimposition

Evolution is brought by the change in the gene frequency of a population over the next generation, which among the following is considered the change in gene frequencies because of chance processes?

• Artificial Selection

• Natural Selection

• Gene Flow

• Genetic Drift

Name the type of mechanisms of evolution that takes place because some female/male species prefer to interbreed with mates that have certain or predetermined qualities.

• Mutation

• Recombination

• Non-random Mating

• Natural Selection

Identify the mechanism of evolution that resulted from the deletion, insertion, substitution, or inversion of DNA because of radiation or copying errors.

• Artificial Selection

• Mutation

• Recombination

• Genetic Drift
