Answer:
The correct option is A, since if the DNA enters in a circular form it is called a plasmid, and the plasmids upon entering the bacteria self-replicate outside the genetic structure, which gives the bacteria better survival qualities.
Explanation:
Plasmids are generally circular extrachromosomal DNA molecules that replicate and transmit independently of chromosomal DNA, and are normally present in bacteria, archaea, and sometimes in eukaryotic organisms such as yeast. Its size varies from 3 to 10 kb. The number of plasmids can vary, depending on their type, from a single copy to a few hundred per cell. Plasmid vectors allow cloning of exogenous DNA ligands of up to 4 kb since a larger size than this makes cloning in these vectors difficult. The term plasmid was first introduced by the American molecular biologist Joshua Lederberg in 1952. Plasmids can only coexist as one or more copies in each bacterium, due to cell division they can be lost in one of the secreted bacteria.
We study sexual anatomy to better understand the process of reproduction in humans. It also can help us better understand how a majority of animals reproduce, and how it can influence ecosystems. I hope this helps, and please mark as Brainliest answer!!
Weathering and erosion are similar in that they both work together to change and shape the Earth's surface. While weathering breaks rock and earth down, erosion is the displacement of the pieces and particles of rock and earth.
Answer: C
Explanation: Thymine pairs with Adenine and Cytosine pairs with Guanine.
Answer:
the insulin
Explanation:
first we take the gene from human cells and we mix them together with bacterial dna.we place them in a fermentation vessel where it will then multiply. then it create the insulin which we use it for people who suffer from diabete.
