Answer:
These bands represent different confirmation of DNA
Explanation:
pGLO DNA is a plasmid DNA that is used as a vector for genetic engineering. Plasmid DNA is found in supercoiled confirmation in vivo. The double helix forms extra twists to easily fit inside the cells. During isolation of plasmid from the cell, nicks can be introduced in the DNA due to harsh isolating methods or contamination by nuclease. As a result the supercoiled confirmation is changed into circular confirmation. It is bulkier than the supercoiled form and travels more slowly. When both DNA stands get cut at the same place, the DNA gets liner confirmation. In the end, supercoiled DNA runs the fastest on gel followed by linear DNA and then the circular DNA.
Answer:
transportation
Explanation:
Transportation (28.2 percent of 2018 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions.
hope this help
Answer:
The correct answer is option A.
Explanation:
The plates used in the skin microbiology experiment incubated at 37-degree celsius due to the microbes grow best at human body temperature which is 37-degree celsius. these bacteria are mesophiles.
The skin microbiology experiments requires conditions as the human skin to perform and study the living and healthy bacteria and some cases fungi.
Thus, the correct answer is option A.
