G proteins are molecules activated by their binding with G protein-coupled receptors (GPCRs).
<h3>What are G proteins?</h3>
G proteins are proteins that act during cellular signaling to transmit information via molecular cascades.
G proteins act by their binding with suitable ligand, where G protein-coupled receptors bind to the G protein and it triggers a molecular cascade.
In conclusion, G proteins are molecules activated by their binding with G protein-coupled receptors (GPCRs).

Conditions affecting either heart or blood vessels are collectively referred to as cardiovascular disease (CVD). Atherosclerosis, a buildup of fatty deposits in the arteries, and a higher risk of blood clots are typically connected with it. Overall, life expectancy could be reduced by 8–10% of what you thought it would be. For instance, a person without heart disease is predicted to pass away around the age of 85, however a heart attack reduces life expectancy by 10%, or 8.5 years.
<h3>Can heart disease be treated?</h3>
Even though coronary heart disease has no known cure, medicines can help manage the symptoms and preventing relapse like heart attacks. Among the proposed therapies include alterations in lifestyle, such as increased physical activity and stopping smoking.

Answer:
The correct answer is A. In early fetal life.
Explanation:
Oogenesis is the process of formation of female gametes in the reproductive organ called ovary. In females oogenesis process starts even before the birth of the female. It starts in fetal stage when primordial germ cells moves from yolk cells to ovaries.
These germ cells are diploid and increase in number to millions by dividing mitotically. Developed germ cells called primary oocytes and during fetal stage they enters in meiosis I and gets arrested in the prophase I stage of meiosis I. This phase is then completed after the puberty takes place.
