​A Little Review

Multiple Choice

Which type of cell has no true nucleus and no membrane-bound organelles?

• Prokaryotic cell

• Eukaryotic Cell

Multiple Choice

True or False: In a sexual reproduction, the offsprings produced are genetically identical (to the parent).

• TRUE

• FALSE

Multiple Select

Which of the following are not examples of body cells?

• epithelial cells

• sperm cells

• neurons

• egg cells

Multiple Choice

True or false: Chromatins are the condensed thread-like structures that carry genetic information. They are made up of DNA and proteins (mostly histones).

• True

• False

Multiple Choice

What is the name of the constricted region of a chromosome where two sister chromatids are joined together?

• centrioles

• centrosome

• centromere

• Kinetochore

Multiple Choice

How many chromosomes are there in a normal human skin cell?

• 48

• 23

• 96

• 46

Cell Cycle

Multiple Choice

At what stage do cells spend most of their time growing, carrying out metabolic processes, and replicating it DNA?

• Mitotic Phase

• Interphase

• Synthesis Checkpoint

• Gap 0 stage?

Multiple Choice

How much of the cell cycle is occupied by cell division?

• 10%

• 50%

• 90%

• 100%

Multiple Choice

A researcher treats cells with a chemical that prevents DNA synthesis from starting. This treatment would trap cells in which part of the cell cycle?

• S-Phase

• M-phase

• G1 Phase

• G2 Phase

Multiple Select

If a checkpoint detects an error during a stage of the cell cycle, what mechanism(s) will the cell possibly activate as a response?

• cell cycle arrest

• cell cycle pause

• cell cycle continuation

• apoptosis

Multiple Select

Which types of cells does not undergo cell division?

• Neurons

• cardiac muscle cells

• stem cells

• sperm cell

​Mitosis

Multiple Choice

The cytoplasm divides, resulting in two separate daughter cells, each with its own nucleus and identical DNA.

• Mitosis

• Telophase

• Cytokinesis

• Metaphase

Multiple Choice

Sister chromatids separate and are pulled toward opposite ends of the cell by spindle fibers.

• metaphase

• prophase

• anaphase

• telophase

Multiple Choice

The chromosomes begin to condense and become visible, while the nuclear envelope starts to break down.

• metaphase

• anaphase

• prophase

• telophase

Multiple Choice

Two new nuclear envelopes form around the separated sets of chromosomes, and the chromosomes begin to uncoil.

• prophase

• metaphase

• anaphase

• telophase

Multiple Choice

Chromosomes line up along the center of the cell, preparing to be divided.

• prophase

• metaphase

• anaphase

• telophase

Multiple Choice

True or False: Mitosis produces daughter cells with different genetic information than the parent.

• TRUE

• FALSE

Multiple Choice

True or False: Mitosis is the process used to make sperm and egg cells.

• TRUE

• FALSE

Multiple Choice

True or False: Daughter cells are identical in chromosome number and genetic content to the parent cell.

• TRUE

• FALSE

Multiple Choice

Prokaryotes and eukaryotes undergo mitosis.

• TRUE

• FALSE

Multiple Choice

The normal human daughter cells from mitosis each have 23 chromosomes each.

• TRUE

• FALSE

​MEIOSIS

Multiple Choice

True or False: Autosomes undergo meiosis.

• True

• False

Multiple Choice

True or False: Meiosis produces 4 identical daughter cells.

• TRUE

• FALSE

Multiple Choice

True or False: The chromosomes in the daughter cell formed through meiosis is diploid.

• TRUE

• FALSE

Multiple Choice

At which stage does crossing over happen?

• Meiosis I

• Meiosis II

Multiple Choice

At what specific stage do sister chromatids get separated?

• Anaphase I

• Anaphase II

​Genetic Disorders

Word Cloud

This disorder is caused by a missing X chromosome (XO) in females, resulting in short stature, a webbed neck, and underdeveloped ovaries. Affected individuals may struggle with infertility and certain learning difficulties, especially in spatial reasoning.

Word Cloud

Individuals with this disorder have an extra chromosome 21, leading to intellectual disability, distinct facial features (such as upward-slanting eyes, a flat nasal bridge, and a small mouth), and a higher risk of heart defects.

Word Cloud

This condition affects males who have an extra X chromosome (XXY), which causes reduced testosterone levels, small testes, breast development, and difficulties with language and social interaction.

Word Cloud

Caused by an extra chromosome 13, this condition leads to severe intellectual disability, cleft lip or palate, extra fingers or toes (polydactyly), and brain or spinal cord abnormalities. Life expectancy is usually very short.

Word Cloud

At which stage of meiosis does nondisjunction typically occur, leading to genetic disorders such as Trisomy 21 (Down syndrome), Trisomy 18, Trisomy 13, or Turner syndrome due to improper separation of chromosomes?
