Question

The Human Genome Project, mentioned in the Code of Life video, was an international scientific research project with the goal of determining the sequence of nucleotide base pairs that make up human DNA. What type of research design was used?

1) correlation
2) description
3) experiment
4) modelling

Answer 1

The Human Genome Project employed a descriptive research design to map out all the DNA base pairs and gene locations in the human genome, providing a comprehensive reference for further study.

Step-by-step explanation:

The Human Genome Project was an international research endeavor aimed at sequencing the complete set of human DNA, which consists of approximately 3.3 billion base pairs. The project used a descriptive research design as it sought to identify and map all the DNA base pairs present in the human genome, as well as to determine the location of over 20,000 genes on our chromosomes. This research design is characterized by systematically recording the characteristics and details of the human genome without manipulating the study environment or variables.

The project began in 1990 and was completed ahead of schedule in 2003. Instead of testing hypotheses or establishing cause-and-effect relationships, the project's purpose was to provide a comprehensive description of the human genome, which would then serve as a reference for further scientific research and medical applications.
