Anucleotide is about to be added to a growing strand of dna. which factor determines which type of nucleotide will be added?
a. base-pairing rules
b. the type of cell in which replication is taking place
c. the length of the dna strand
d. random chance

The correct answer is- A) Base-pairing rules.

DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.

The strands of double helical DNA are first separated so that the template DNA strands are exposed.

DNA polymerase adds nucleotides in the newly growing according to the Watson and Crick base pairing. The rules according to this base pairing are as follows-

1) Adenine pairs with Thymine ( through 2 bonds of hydrogen).

2) Cytosine pairs with Guanine ( through 3 bonds of hydrogen).

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
