Questions about the manipulation of an organisms genes in order to alter the morphological or chemical traits of the organism.

1,706 Questions

Is there a gene for determination?

There isn't a single gene responsible for determination, as it is a complex trait influenced by multiple genetic and environmental factors. Traits like determination are believed to be polygenic, meaning they are controlled by multiple genes working together. Additionally, personal experiences and upbringing also play a significant role in shaping an individual's level of determination.

How can genetic variation be introduced to sexually reproducing organisms?

Genetic variation can be introduced to sexually reproducing organisms through processes like meiosis, which shuffles and recombines parental genetic material to create new combinations. Additionally, mutations can also occur spontaneously during DNA replication, resulting in new genetic variations. Finally, the process of sexual reproduction itself, which involves the mixing of genetic material from two individuals, further increases genetic diversity in a population.

Which part of bacteria houses the genetic material?

The genetic material of a bacteria is housed within the nucleoid region of the cell, which is a concentrated area within the cytoplasm where the bacterial chromosome is located. It is not surrounded by a membrane like in eukaryotic cells.

When insulin was being commercially produced in genetically engineered bacteria and yeast it was obtained from the pancreas of what?

When insulin was being commercially produced in genetically engineered bacteria and yeast, it was obtained from the pancreas of pigs and cows. This animal insulin was then purified and used as a template to create synthetic human insulin through genetic engineering processes.

Is stinky feet a genetic disorder?

Stinky feet are typically not a genetic disorder. They are commonly caused by a combination of factors like sweating, bacteria on the skin, and wearing shoes that trap moisture. Good foot hygiene, wearing moisture-wicking socks, and changing shoes regularly can help alleviate foot odor.

How much genetic information is passed from parent to offspring?

Half of the genetic information is passed from each parent to their offspring. Offspring inherit half of their genetic material from their mother through the egg and half from their father through the sperm, combining to form a full set of genetic information.

What genetic abnormality causes phenylketonuria?

Phenylketonuria (PKU) is caused by mutations in the PAH gene, which provides instructions for making an enzyme called phenylalanine hydroxylase. This enzyme is essential for the breakdown of the amino acid phenylalanine. Mutations in the PAH gene lead to a deficiency in this enzyme, resulting in a build-up of phenylalanine in the body.

What are the two broad areas of use and two examples after a host cell grown in culture to form a clone of cells containing the cloned gene of interest?

The two broad areas of use for cloned cells containing a gene of interest are medical research and biotechnology. Examples include using the cells to study gene function in disease models and to produce recombinant proteins for therapeutic purposes.

How does a cell divide to create cells with exactly half of the original cells genetic information?

During cell division, the cell's genetic material is duplicated and then segregated evenly into two daughter cells. This process, known as mitosis, ensures that each daughter cell receives an exact copy of the genetic information from the original cell, leading to cells with half of the original cell's genetic material.

What cell structure contains the majority of genetic material?

The cell nucleus contains the majority of the genetic material in eukaryotic cells. It houses chromosomes, which are composed of DNA and protein and carry the cell's genetic information.

How does independent orientation of chromosome during meiosis increase genetic variation?

Independent orientation of chromosomes during meiosis ensures that each gamete receives a random assortment of chromosomes. This shuffling of genetic material leads to a greater diversity in the combination of traits in the offspring. This process increases genetic variation by creating new combinations of alleles.

Are human clones hated by humans?

Opinions on human clones vary widely among individuals and societies. Some people may feel uncomfortable or fearful about the concept of human cloning, while others may be more accepting or curious. In fiction and popular media, human clones are often portrayed in a negative light, which can influence public perception.

Is the inner core of a virus contains genetic material?

Yes, the inner core of a virus typically contains the genetic material, which can be either DNA or RNA. This genetic material carries the instructions for the virus to replicate and infect its host cells.

What would decrease genetic variation in a population?

Inbreeding, genetic drift, and natural selection can decrease genetic variation in a population by reducing the number of different alleles present. These processes can lead to a loss of genetic diversity and increase the prevalence of certain genetic traits within the population.

Why does variation occurs?

Variation occurs due to differences in genetic makeup, environmental factors, and random mutations in populations. These variable factors contribute to the diversity seen among individuals within a species.
