Which of the following events occurs during transcription?
a. those segments of the rna strand that do not actually code for the protein are removed.
b. a molecule of rna is formed based on the sequence of nucleotides in dna.
c. the message in mrna is translated into a protein.
d. a cap is added to the rna molecule.
mrna binds to a ribosome in the cytoplasm.

Letter B. A molecule of RNA id formed based on the sequence of nucleotides in DNA

Explanation:

The process to form a protein from the information in genes are called the central dogma of molecular biology, this dogma consists of two main steps.

          Transcription                  Translation

DNA           to →               RNA         to →            Protein

The first one consists in to obtain a molecule of RNA using DNA molecules as a template, this RNA contains a message from the DNA. In the next step the RNA molecule act as a messenger (also called mRNA) because it   contains the information to form a protein, in this point there are others additional steps, for example, removing the segments in the RNA that do not code a protein or the mRNA is modified to  binds  a ribosome ( structure that can “read” the message in the mRNA to form a protein).

To sum up, in transcription, we obtain a molecule of RNA that comes from DNA. The translation is the process to read de RNA to form a protein.
