Which of the following best describes meiosis?
-
Cell division that occurs only in the reproductive structures of an organsim
-
Process prior to the first stage of cell division
-
Occurs in all cells of the body
-
Cell division that occurs in the repair process of damaged skin
Correct Answer
A. Cell division that occurs only in the reproductive structures of an organsimExplanation
Meiosis is a type of cell division that specifically occurs in the reproductive structures of an organism. It is a specialized process that results in the formation of gametes (sperm and eggs) with half the number of chromosomes as the parent cell. This is necessary for sexual reproduction and ensures genetic diversity in offspring. Meiosis is not a process that occurs in all cells of the body or in the repair process of damaged skin.Rate this question:

Which of the following is a difference between asexual reproduction and sexual reproduction?
-
Sexual reproduction leads to greator amounts of genetic variation
-
They are the same in terms of genetic variation
-
They both occur in somatic cells
-
Sexual reproduction leads to less genetic variation
Correct Answer
A. Sexual reproduction leads to greator amounts of genetic variationExplanation
Sexual reproduction leads to greater amounts of genetic variation because it involves the fusion of genetic material from two different individuals, resulting in offspring with a combination of traits from both parents. This mixing of genetic material through processes like recombination and crossing over during meiosis leads to the creation of new gene combinations, increasing genetic diversity. In contrast, asexual reproduction involves the production of offspring from a single parent, resulting in genetically identical or nearly identical offspring, leading to less genetic variation.Rate this question:

Meiosis plays a more significant role in reproduction than mitosis in which of the following?
-
Increasing the variability of genetic information
-
More efficiently using energy in the cell division process
-
More rapidly reproducing and growing
-
Increasing the process of asexual reproduction
Correct Answer
A. Increasing the variability of genetic informationExplanation
Meiosis plays a more significant role in reproduction than mitosis in increasing the variability of genetic information. During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment, resulting in new combinations of genes. This leads to the production of genetically diverse gametes, which are necessary for sexual reproduction and the creation of offspring with unique genetic traits. In contrast, mitosis is responsible for the growth and repair of cells and produces genetically identical daughter cells.Rate this question:

If the diploid number at the start of meiosis is 8 chromosomes, what will the number of chromosomes be in each of the daughter cells?
-
4
-
2
-
8
-
6
Correct Answer
A. 4Explanation
The purpose of meiosis is to half the number of chromosomes so that they can unite with a gamete with the other half to increase genetic variation.Rate this question:

When one or more nucleotides are lost during chromosomal crossover during meiosis this is called...
-
Substitution mutation
-
Deletion mutation
-
Translocation mutation
-
Inversion mutation
Correct Answer
A. Deletion mutationExplanation
During chromosomal crossover in meiosis, when one or more nucleotides are lost, it is referred to as a deletion mutation. This type of mutation involves the removal of genetic material from a chromosome, resulting in the loss of specific nucleotides. This can lead to significant changes in the genetic code and potentially disrupt the functioning of genes. Deletion mutations can have various effects depending on the location and size of the deletion, ranging from mild to severe genetic disorders.Rate this question:

Compared with mitosis, meiosis produces
-
Greater number of cell chromosomes per cell
-
Greater volume of cell cytoplasm per cell
-
Greater number of daughter
-
Greater amount of genetic material per cell
Correct Answer
A. Greater number of daughterExplanation
Meiosis produces a greater number of daughter cells compared to mitosis. In meiosis, one parent cell divides into four daughter cells, each with half the number of chromosomes as the parent cell. This is essential for sexual reproduction as it ensures that the resulting offspring have the correct number of chromosomes. In contrast, mitosis produces two daughter cells that are identical to the parent cell, with the same number of chromosomes. Therefore, meiosis is responsible for increasing genetic diversity and creating gametes for sexual reproduction.Rate this question:

In cellular reproduction which of the following processes occurs the same number of times in meiosis as it does mitosis?
-
The cytoplasm is divided evenly between the cells.
-
The DNA in the chromosomes is duplicated.
-
The cells divide in equally sized halves.
-
The chromosomes align themselves at opposite ends of the cell.
Correct Answer
A. The DNA in the chromosomes is duplicated.Explanation
In both meiosis and mitosis, the DNA in the chromosomes is duplicated. This is an essential step in both processes to ensure that each daughter cell receives a complete set of genetic information. During DNA duplication, the DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical copies of each chromosome, which are then segregated to the daughter cells during cell division. Therefore, the process of DNA duplication occurs the same number of times in both meiosis and mitosis.Rate this question:

The DNA regions that code for proteins are...
-
Introns
-
Promoters
-
Exons
-
Initiators
Correct Answer
A. ExonsExplanation
Exons are the DNA regions that code for proteins. They are the segments of DNA that are transcribed into mRNA and eventually translated into amino acids to form proteins. Introns, on the other hand, are non-coding regions that are removed during mRNA processing. Promoters are DNA sequences that initiate gene transcription, and initiators are specific sequences that signal the start of transcription. Therefore, exons are the correct answer as they are the specific regions of DNA that contain the coding information for proteins.Rate this question:
