Answer:
Labeled ddNTPs
Explanation:
The chain termination method or sanger method consist in 4 synthetis reaction at the same time. Each of them with a different labeled ddNTPs (ddATP, ddCTP, ddGTP and ddTTP) as part of it sythesis sustract. As the reaction goes on, if a ddNTP is added to the new DNA chain, it will stop the elongation becouse DNA polymerase activity depends on the presence of -OH extremes which are miss on ddNTPs.
Answer:
1.31 cM
Explanation:
Total offspring = 2205
Since two genes are involved, F1 progeny should have four types of combination. Out of them two are 17 and 12 which definitely means they are in lesser number. Since recombinants are always less than parental progeny in linkage, the given two types are recombinants.
Recombination frequency = (Number of recombinants / Total progeny) * 100
= [ ( 17 + 12 ) / 2205 ] * 100
= ( 29 / 2205 ) * 100
= 1.31 %
Map distance = Recombination frequency
Hence, distance between two genes = 1.31 cM
Since hydropower is powered by water, it’s a good fuel source. It will not contaminate the air like power plants that release fossil fuels, for example coal and oil. It does not rely on international fuel sources and lets each state make their own energy.
The answer is C. a double helix
Answer:
The model that does the best job of showing osmosis is "Thomas. Student-drawn membrane model within a rectangular box. From left to right there is an upper and lower line spaced moderately apart."
Explanation:
Osmosis: this is a process of which molecules of a solvent pass through a semipermeable membrane from a lower concentrated solution into a more concentrated solution.
