Genetic engineering involves the use of recombinant DNA technology, the process by which a DNA sequence is manipulated in vitro, thus creating recombinant DNA molecules that have new combinations of genetic material
What else can I help you with?
How does meiosis introduce genetic variation into offspring?
1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .Meiosis produces variation in gametes by crossing over & independent assortment also called reshuffling of genetic material . Such gametes after fertilization produce offspring with different characters .
In a particular population sexual reproduction can produce?
In a particular population, sexual reproduction can produce offspring with genetic variation, allowing for increased adaptability to changing environments. It also allows for the elimination of harmful genetic mutations through recombination and gene shuffling. This can lead to increased genetic diversity within the population.
How does the process of meiosis differ from mitosis in terms of genetic variation and cell division?
In meiosis, cells divide twice to produce four genetically unique cells with half the number of chromosomes, leading to increased genetic variation. In contrast, mitosis results in two identical cells with the same number of chromosomes as the original cell.
How can genetic technology allow us to create human insulin using bacteria?
We are able to "splice" genes from one organism into the DNA of another to give it traits we want. In this case, we put the gene for insulin into the DNA of a bacterium, which causes it to produce insulin, which we can use.
Griffith's experiment showed that live bacteria without capsules acquired the ability to make capsules from dead bacteria with capsules in a process griffith called?
Griffith's experiment demonstrated bacterial transformation, where genetic material from dead bacteria was taken up by live bacteria, resulting in the acquisition of new genetic traits, such as the ability to produce capsules. This process, also known as horizontal gene transfer, played a crucial role in understanding how genetic information can be transferred between bacteria.
Ability of bacteria to produce insulin was result of?
Genetic engineering of the bacteria.
Does meiosis increase or decrease biodiversity?
Meiosis increases biodiversity by generating genetic variation through processes like crossing over, independent assortment, and random fertilization. These mechanisms shuffle and combine genetic material to produce a wide range of unique genetic combinations in offspring.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
Tetracycline is used in genetic engineerin experiments as a way to?
Produce stronger strains of bacteria
What is bacterial genetics?
Bacterial genetics is the study of the mechanisms by which bacteria inherit traits from their parent cells, including the transfer of genetic material through processes like conjugation, transformation, and transduction. By understanding bacterial genetics, researchers can study how bacteria evolve, develop resistance to antibiotics, and cause infections. This field has also led to the development of genetic engineering techniques for manipulating bacteria to produce useful proteins or to study specific genes and their functions.
How could people use the genetic variation in wild roses to create roses that produce large flowers?
cross breed them
In regards to taxonomic classification of bacteria what is the relationship between physiological and genetic differentiation of bacteria?
You're lame typing the answer as exactly as it is on the lab manual......I.V. Genetic differences between bacteria causes specific physiological differences among the bacteria, such as certain morphological characteristics as well as what compounds the bacteria can ferment and produce as by-products in this process.
Which type of reproduction results in the greatest amount of genetic variation?
That would be sexual reproduction. Sexual reproduction allows for independent assortment and crossing over to occur. This is fancy language for the genetic material gets mixed up a lot. Since the genetic material gets mixed up, variation will result.
Many diabetics are now using insulin that was made by certain bacteria The ability of these bacteria to produce insulin was most likely the result of?
genetic engineering techniques such as recombinant DNA technology, where the gene encoding for insulin production was introduced into the bacterial DNA. These bacteria then use this genetic information to produce insulin, which can be harvested for diabetic treatment.
Which description does not apply equally well to both sexual and asexual spores?
The ability to undergo meiosis and produce genetic variation does not apply equally well to both sexual and asexual spores. Sexual spores are formed through meiosis, which shuffles genetic material and leads to genetic variation. Asexual spores, on the other hand, are produced by mitosis and do not contribute to genetic diversity.
Four examples of genetic engineering?
Genetic engineering can be done with animals, produce and bacteria. Organisms that undergo genetic engineering are called genetically modified organisms. Some of the earliest GMOs were bacteria and mice. Food products, glofish and zebra fish are some of the more recent GMOs.
Reproduction that does not produce variation among the offspring?
Asexual reproduction does not produce genetic variation among offspring, as the new organisms are exact copies of the parent organism. This process involves only one parent and typically occurs through methods such as budding, regeneration, or binary fission.
