Explanation:

AlphaFold is an Artificial Intelligence-based protein structure prediction tool. It is based on a computer system called Deep Neural Network. 

• Neural networks use a large amount of input data and provide the desired output exactly like how a human brain would.
• AlphaFold is not the only AI-based protein structure prediction tool. RoseTTaFold, developed by University of Washington in Seattle, U.S., is another tool which can predict the structure of protein complexes. Although less accurate than AlphaFold.

Hence only statement 1st is  correct.
