Question

All organisms undergo protein synthesis. the first step of protein synthesis, in which a dna strand is used to make a complementary mrna strand, is called?

Answer 1

Answer:

Transcription.

Explanation:

Protein synthesis involves formation of protein molecules by using information present in the DNA of the cell. The first step of protein synthesis is transcription, during which DNA strand is used as a template to synthesize a complementary mRNA strand. Enzyme involved in mRNA synthesis is RNA polymerase that uses information from parent DNA molecule.

Thus, the correct answer is 'transcription.'

Answer 2

Transcription is the first step of protein synthesis.
