The purpose of synthetic biology is to create artificial biological systems. We connect a certain amount of gene to build gene network, making them run like a circuit. According to this principle, the game players play an engineering bacterium and look for gene fragments in each level of adventure, to form a complete genetic line, so that the engineering bacteria can be changed to special bacteria that are used to solve disease or environmental problems.

The operation of this game is simple and flexible. The left key controls the role move towards left and the right key controls it move towards right. In this game, player tries to find possible solutions about the disease and environmental problems which human beings pay close attention to. The game involves the knowledge of synthetic biology, including gene lines, transformation of engineering bacteria, disease monitoring and so on, which can introduce synthetic biology to a certain amount of teenagers, and deepen their understanding of the ways to solve disease and environmental problems.

The goal of making this game is embedding science into game, to expand the accepting crowd of scientific knowledge. This game is a 2D horizontal board scroll category casual games. Each level of the game contains the method of a specific disease environmental problem, and different levels have different story backgrounds and ways of playing, which make the game become more interesting to play.

China resumed sovereignty over Macao in December 1999 after it had been ruled since the mid-16th century by Portugal.

Beijing is willing to carry out major projects with these countries by making use of the China-Portuguese-Speaking Countries Cooperation Development Fund and the Silk Road Fund, Li said.

The announcement was made in Li's keynote speech on Tuesday at the opening ceremony of the two-day Fifth Ministerial Conference of the Forum for Economic and Trade Cooperation Between China and Portuguese-Speaking Countries.

Delegates from seven Portuguese speaking countries — Portugal, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Angola and East Timor — attended the forum.

Before the ceremony, Li launched a trade and economic cooperation program to promote further exchanges between China and Portuguese-speaking countries.

China and the Portuguese-speaking countries contribute 17 percent of the world economy and 22 percent of global population, with varying advantages in technology, capital and market practices, Li said.

The participating countries should consolidate political trust, promote trade liberalization and investment and strengthen cooperation in production capacity and people-to-people exchanges, the premier told the forum.

China's economic restructuring and upgrading will bring great investment opportunities and market potential, creating bright prospects for businesses from Portuguese-speaking countries, Li said.

He said the trade volume between China and Portuguese-speaking countries reached $100 billion last year — about 10 times of that of 2003.

Cape Verde's Prime Minister Ulisses Correia e Silva said the Macao forum injected new momentum into strategic cooperation between all the participating countries. He added that his country will align with China's Belt and Road Initiative and make use of the Macao forum to bring more commodities to Africa.

The prime ministers of Guinea-Bissau and Mozambique vowed to adopt favorable policies and improve the rule of law to attract investors.
