The Sanger method of DNA sequencing uses a mixture of dNTPs and ddNTPs, which are missing oxygen atoms at both the 2' and 3' carbons. What is the role of the ddNTPs? A.

They stop replication because they are not able to bind to the growing DNA strand.

B.

They stop replication because the next nucleotide in the growing strand cannot bind to them.

C.

The enhance replication because DNA polymerase selectively adds them to the growing DNA strand.

D.

They enhance replication because they form additional hydrogen bonds with the complimentary DNA strand.

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

Which short-term environmental change is most likely to lead to ground shifting, landslides, and the collapse of buildings or roads? forest fires flooding earthquakes

What is the main difference between the central nervous system (cns) and the peripheral nervous system (pns)? .the cns involves the brain and spinal cord, and the pns involves the body nerves. the cns involves the body nerves, and the pns involves the brain and spinal cord. the cns involves sensory neurons, and the pns involves motor neurons. the cns involves motor neurons, and the pns involves sensory neurons.
