Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Select three answers that apply. A. completing a full sequence of human DNA (the Human Genome Project) B. identifying the regions of human DNA that are transcribed into RNA C. identifying the regions of human DNA that bind to proteins D. analyzing the regions of human DNA that vary among individuals E. describing the molecular structure of human DNA

B. identifying the regions of human DNA that are transcribed into RNA

C. identifying the regions of human DNA that bind to proteins

D. analyzing the regions of human DNA that vary among individuals

Explanation:

The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.
