Answer: A. A blockage in the aorta

Explanation:

A heart attack happens when one or more aorta or coronary arteries get blocked. With the passage of time, the coronary artery becomes narrow that is because of the deposition of various substances such as fat, cholesterol and other reserves. This restricts the smooth circulation of blood hence results in heart attack or heart stroke.

Question:

The complete question has these options:

A) tRNA with anticodons is carrying amino acids to the ribosomes.

B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.

C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Answer:

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Explanation:

During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing

A) tRNA with anticodons is carrying amino acids to the ribosomes.  - this is not evidence of transcription but is instead evidence of translation

B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.  - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.

C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins  - this is not evidence of transcription but is instead evidence of translation

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.
