Which molecule is recombinant DNA? A) A gene that encodes an enzyme involved in glycolysis that was obtained in the wild from a
hybrid between a wolf and a coyote B) A stretch of DNA that encodes an insulin molecule, created synthetically by chemists in the lab C) A stretch of DNA that does not code for anything, created by pasting together DNA from a mouse and DNA from a bacterium D) A stretch of DNA that does not code for anything, from a tomato grown in a garden E) A gene that codes for a photosynthetic enzyme found in a tomato grown in a garden
C) A stretch of DNA that does not code for anything, created by pasting together DNA from a mouse and DNA from a bacterium.
Explanation:
The DNA that is produced artificially by combining the DNA of different individuals or different organisms is known as recombinant DNA.
These recombinant DNA can be used for different purposes like for the production of recombinant products like recombinant hormone in the host organism, for example, production of human insulin in bacteria.
So if a segment mouse DNA and a segment of bacterial DNA are pasted together then it will be called recombinant DNA because the resultant DNA is made up by the recombination of DNA of two different organisms.
The type of asexual spore that a fungi produces can be very helpful in the identification of species. When, fungi produce spores asexually by mitosis, the genetic makeup of spores is exact same as the parent specie. So, by examining the spore the most accurate estimate of a specie can be done.
