Firstly, the enzyme, DNA Helicase breaks the Hydrogen bonds between a specific region of the DNA molecule and unwinds the duplex DNA molecule at the targeted gene sequence site.
Then, RNA Polymerase binds at the 3` site of the gene sequence of the sense/coding strand(only one strand) that acts as the template for mRNA synthesis. RNA Polymerase then matches free nucleotides by complementary base-pairing(A-U & C=G), working in the 5`to3` direction. Hydrogen bonds then form between the complementary bases, holding the nucleotides in place. Each free adjacent nucleotide is joined at 3` ends by Condensation reactions with the other to form Phosphodiester bonds.
Once the mRNA molecule is formed, it is separated from the synthesis complex and leaves the nucleus through pores in the nuclear envelope to moves towards ribosomes for Translation.
Lastly, the DNA double helix rewinds by forming Hydrogen Bonds.

Answer:
homozygous recessive
Explanation:
Cystic fibrosis is a recessive genetic disorder. It means that the trait is caused due to the presence of a recessive allele. The recessive alleles are expressed only in homozygous recessive genotypes. Individuals that express the disorder cystic fibrosis should have two copies of a recessive allele of the gene, that is, the genotype should be homozygous recessive.
If "C" allele is the normal healthy allele and "c" allele is cystic fibrosis allele, the genotype of the affected individual would be "cc".
Answer:
If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much
Explanation:
The force of gravity between two objects is doubled if the mass of one of the objects is doubled.
If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much, since the gravitational force is proportional to the masses of both the Earth and the Moon.
