Answer:
25000 fragments
Explanation:
A restriction enzyme can cut a random DNA sequence once per every 4^n where n = number of bases in the recognition site of enzyme.
There are 6 bases in Xbal's recognition site (TCTAGA) so it will cut once per every 4^6 = 4096 bases (4kb).
Total genomic size = 100000kb
So expected number of fragments = Total genomic size/Size of one fragment
= 100000/4
= 25000 fragments
Answer:
561
Explanation:
This is math so I got you.
This is just going to subtract 12 from 55 since we don't now when during her 12th year of age she started or when during her 55th year f age she ended.
55 - 12 = 43, so about 43 years. Also not going to account for leap years. So we are just going to say each year had 365 days. so 43 years and 365 days per year = 15695 days.
If her cycles were each about 28 days we divide the total number of days by 28 and that tells us about how many cycles there were.
15,695 / 28 = 560.5 which I will round to 561
561 cycles means 561 eggs if my biology knowledge is as accurate as I think it is.
Answer:
a long rodlike structure that develops dorsal to the gut and ventral to the neural tube. The notochord is composed primarily of a core of glycoproteins that are encased in a sheath of collagen fibers wound into two opposing helices.
Pollination is a very important part of the life cycle of plants. Insects, birds, bats and the wind take pollen between flowering plants, which means the plants can make seeds and reproduce (have babies!).
Answer:
Prokaryotic cells are larger than eukaryotic cells. Eukaryotic cells do not have nuclei, and prokaryotic cells do have nuclei. Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles.
