Question

models of organisms for experimental purpose are kept in ________​

Answer 1

Answer:

formulae us the correct answer

Answer 2

Explanation:

•A model organism is a species that has been widely studied, usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages.

•Model organisms are non-human species that are used in the laboratory to help scientists understand biological processes.

•They are usually organisms that are easy to maintain and breed in a laboratory setting.

For example, they may have particularly robust embryos? that are easily studied and manipulated in the lab, this is useful for scientists studying development.

•Or they may occupy a pivotal position in the evolutionary tree, this is useful for scientists studying evolution.?

•Why are model organisms useful in genetics research?

•Many model organisms can breed in large numbers.

Some have a very short generation time, which is the time between being born and being able to reproduce, so several generations can be followed at once

Mutants allow scientists to study certain characteristics or diseases. These are model organisms that have undergone a change or mutation? in their DNA? that may result in a change in a certain characteristic.

•Some model organisms have similar genes? or similar-sized genomes? to humans.

Model organisms can be used to create highly detailed genetic maps:

•Genetic maps are a visual representation of the location of different genes on a chromosome?, a bit like a real map but one where the key landmarks are areas of interest in the genome.

•For example, areas of DNA that differ between individuals in the same species (SNPs?) or genes.

Examples of model organisms used to study genetics

•Yeast (Saccharomyces cerevisiae)

•Fruit fly (Drosophila melanogaster)

•Nematode worm (Caenorhabditis elegans)

•Western clawed frog (Xenopus tropicalis)

•Mouse (Mus musculus)

•Zebrafish (Danio rerio)
