Which of the following statements regarding the Human Genome Project (HGP) and its findings are correct? S1: Human genome project aimed to identify approximately 20,000-25,000 genes in human DNA. S2: The entire process of DNA sequencing was completed using only manual sequencing methods due to the immense scale and complexity of the human genome. S3: Bacterial Artificial Chromosomes (BACs) and Yeast Artificial Chromosomes (YACs) were utilized as vectors for cloning large DNA fragments in their respective hosts. S4: Less than 2% of the human genome is known to code for proteins, while repetitive sequences constitute a very small portion of the total genome. S5: Chromosome Y is identified as the human chromosome containing the highest number of genes, providing unique genetic insights.
