Information about protein synthesis is strong in the ______
Answers
Answer:
DNA helicase breaks the hydrogen bonds between base pairs and thereby separates two DNA strands. The template strand serves in mRNA synthesis while the other strand is called as coding strand as its base sequence is same as that of newly synthesized mRNA. Option A is correct. RNA polymerase enzyme adds ribonucleotides to synthesize RNA using the base sequence of template DNA strand. Triplet codons are present in mRNA and serve as the template for protein synthesis. DNA polymerase is the enzyme of DNA replication. Option B is incorrect. The primary transcript synthesized during transcription undergoes processing to produce a functional RNA and is transported to the cytoplasm. Binding of mRNA to 30S ribosomal subunit and initiation factors marks the initiation complex to start protein synthesis. Option C is correct. Each of the 20 amino acids, present in cell pool, is covalently attached to a 3’ end of specific tRNA using ATP by enzyme aminoacyl-tRNA synthetases; this charged tRNA carries the linked amino acid to the ribosome. Option D is correct.
Answer:
The type of RNA that contains theinformation for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.
