Hello. This question is incomplete. The full question is:
"You determine that you have only 3 copies left of an important DNA fragment, so you decide to amplify it. Using flanking primers, how many PCR cycles would you have to run to generate over one billion (10^9) copies of the fragment?
"
Answer:
Approximately 29 cycles of PCR would be required.
Explanation:
As you may already know, PCR is a technique used in molecular biology that allows part of a DNA molecule to be recycled into millions of copies.
PCR allows this replication to be done through cycles. Each PCR cycle lasts about 2 minutes and allows the DNA molecule to undergo the separation of the strands, the binding of the primers and the synthesis of new DNA strands through DNA polymerase. This cycle is usually repeated 32 times, but this number may change depending on the number of copies the researcher thinks is necessary.
In this case, if a researcher wants 10 ^ 9 copies of DNA, he must do the following calculation to find the number of PCR cycles needed:
32 ^ x = 10 ^ 9
x = 28.3 = approximately 29 cycles.
S waves are slower than P waves and they can only travel through solid rock. S waves move the particles it pushes through up and down or side to side (perpendicular to the motion of the S waves energy).
1,560,000 milliseconds is 26 minutes and 26 minutes is about .43 hr
so the second one is the correct answer
Answer:
it is because this Complex carbohydrates always takes longer time to digest and are a more sutiable source of energy than simple carbohydrates. ... As also the complex carbohydrates have more longer chains, and they take more time longer to break down and provide more lasting energy in the body than simple carbohydrates. Both types of carbohydrate are often present in many foods.
Explanation:
Answer:
introns will remain inside the bacteria
Explanation:
Introns are the remains of an RNA transcript that do not involve in coding and hence they are trimmed off once the protein is translated from the RNA molecule.
Introns are found more commonly in eukaryotic genomes as compared to bacterial and archaeal genes
Group I introns have an ability to invade tRNA, rRNA and protein through its intervening sequences however their insertion into genes is phenotypically neutral.
