andre [41]

Answer:

"The smallpox vaccine does not contain smallpox virus and cannot spread or cause smallpox. However, the vaccine does contain another virus called vaccinia which is live in the vaccine. Because the virus is alive, it can spread to other parts of the body or to other people from the vaccine site."

In this metabolic process, the enzyme RNA polymerase binds RNA nucleotides (the substrates) together by catalyzing the formation
stira [4]

Answer:

TRANSCRIPTION

Explanation:

Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.

RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.

In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.
