Biology PMA 3 Review-OCPS

Which process is shown?

• diffusion
• repiration
• recombination
• translation

How many gametes are produced at the end of meiosis II?

• 2
• 3
• 4
• 8

Crossing-over is an important process in meiosis cell division in that:

• it allows for genetic recombination within gametes found in an individual. This is why you may have blonde hair, but you mom or dad does not have blonde hair.
• it allows for the chromosomes to split apart during prophase I, within which they are able to pair up and design the DNA that makes up an individuals gametes.
• it allows for people to have many different cells that provide the structure to form new somatic cells.
• none of the answers are correct

Sexual reproduction uses the process of meiosis to increase genetic diversity. Offspring created through asexual reproduction (mitosis) are genetically identical to their parent, but the germ cells created during meiosis are different from their parent cells.

• FALSE

How would you be able to tell if two chromosomes were homologous?

• Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during anaphase I, within which the chromosomes share genetic information (DNA).
• Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during metaphase I, within which the chromosomes share genetic information (DNA).
• Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during prophase I, within which the chromosomes share genetic information (DNA).
• Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during prophase II, within which the chromosomes share genetic information (DNA).

Which of the following events occurs in both meiosis and mitosis?

• prophase I - the major event is crossing-over.
• anaphase I - this is where the homologous chromosomes are separated.
• interphase - this occurs only one in both meiosis and mitosis
• metaphase I - This is where homologous chromosomes line up in pairs in the middle of the cell.

Which of the following processes occurs only in meiosis, but not in mitosis?

• Interphase - this is where the cell performs cellular processes essential for life.
• Prophase I - Crossing-over occurs, within which the chromosomes are sharing their DNA with identical genes.
• Metaphase I - This is where the chromosomes line up in the middle of the cell.
• there is no alikeness between meiosis and mitosis.

Which of these is NOT a part of the Cell Theory?

• All cells contain a nucleus

• Cells are the basic unit of living things.

• All living things are one or more cells

• Cells come from cells
