Why does a new DNA strand elongate only in the 5' to 3' direction during DNA replication? (A) DNA polymerase begins adding nucle
Georgia [21]

A new DNA strand elongate only in the 5' to 3' direction during DNA replication because the  "polarity of the DNA molecule prevents addition of nucleotides at the 3' end" .

DNA replication occurs in the 5' to 3' direction. DNA polymerase can only add nucleotides to the 3' OH group of the growing DNA strand, this is why DNA replication occurs only in the 5' to 3' direction.

DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered. Consequently, synthesis proceeds immediately only along the so-called leading strand.

Hence, the correct answer will be option (B)

Does anyone know this??
Mandarinka [93]

Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.
