📖 NCERT Source

Deriving meaningful knowledge from the DNA sequences will define research through the coming decades leading to our understanding of biological systems. This enormous task will require the expertise and creativity of tens of thousands of scientists from varied disciplines in both the public and private sectors worldwide. One of the greatest impacts of having the HG sequence may well be enabling a radically new approach to biological research. In the past, researchers studied one or a few genes at a time. With whole-genome sequences and new high-throughput technologies, we can approach questions systematically and on a much

Which of the following statements about the Human Genome Project (HGP) and its outcomes are NOT correct? S1: The Human Genome Project was primarily a 5-year initiative aimed at exclusively sequencing the coding regions of the human DNA. S2: Expressed Sequence Tags (ESTs) represented an approach focused on identifying all genes that are transcribed as RNA. S3: One of the major findings was that approximately 99.9% of nucleotide bases are identical in all humans, highlighting minimal genetic variation. S4: Repetitive DNA sequences, which form a significant portion of the human genome, are thought to have direct coding functions. S5: The project identified approximately 1.4 million locations of Single Nucleotide Polymorphisms (SNPs), which are crucial for tracing human history and disease association.
