Answer: The earth's atmosphere support life on earth by protecting us from the UV rays and slows down asteroids before they hit the earth. And protects us from much more stuff.
Explanation:
Answer: 20 fragments
Explanation:
This particular restriction enzyme has a 4 bp (base pair) recognition sequence therefore it will cleave once every 4ⁿ bases where n indicates the number pf bases in the recognition sequence.
- The recognition sequence is 4 bp therefore this restriction enzyme cleaves once every 4⁴ = 256 bases. This is the length of the restriction fragment.
- Calculate the number of fragments by dividing the total number of bases ( where you assume equal frequency of bases ie. A+T = C+G) by the length of the restriction base.
- therefore 5000bp/256bp = <u>19,53</u> now this number ca n be rounded up to 20.
- The expected number of fragments on the electrophoresis gel will be 20 fragments.
The earth surface and when the sun and earth move. Plus the north and South hemisphere
Answer:
Mass of reactants = Mass of products.
Explanation:
We co serve mass in this law so the start and end have to have the same mass. this the equal sign.
