Snails are grouped in the Class gastropoda, which is part of the mollusk phylum

Explanation:

The snails are the gastropods which forms the majority of this group class. The class gastropoda falls in the phylum mollusca which is part of animal kingdom as an invertebrates.

there are six kingdoms divided on the basis of classification given by Whitaker. One of those kingdoms is the animal kingdom, which is further divided into invertebrates and vertebrates. both of them are divided into several phylum which are then divided into classes and subclasses to the order to genus and species, in the taxonomical grouping or classification.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
