[1] What Is Molecular Biology? Key Concepts, Techniques ... - Excedr — Gene therapy is another discipline in molecular biology that has been developed to modify, enhance, or suppress certain genes in an organism in order to treat or prevent disease, rather than relying on drugs to support immune responses and the nervous system. Molecular biology is a relatively recent field in science that came to prominence in the mid-1900’s due to important scientific discoveries that allowed scientists to visualize the structures of biological macromolecules and better understand molecular mechanisms and processes. Since its initial introduction and development, many different techniques have been created to further understand the processes of how DNA and proteins interact and function in cells, and studies including biochemistry and cell biology continue to increase our understanding of cell function on a microscopic and molecular level.

[2] Molecular biology - Wikipedia — The term 'molecular biology' was first used in 1945 by the English physicist William Astbury, who described it as an approach focused on discerning the underpinnings of biological phenomena—i.e. uncovering the physical and chemical structures and properties of biological molecules, as well as their interactions with other molecules and how these interactions explain observations of so-called classical biology, which instead studies biological processes at larger scales and higher levels of organization. In 1953, Francis Crick, James Watson, Rosalind Franklin, and their colleagues at the Medical Research Council Unit, Cavendish Laboratory, were the first to describe the double helix model for the chemical structure of deoxyribonucleic acid (DNA), which is often considered a landmark event for the nascent field because it provided a physico-chemical basis by which to understand the previously nebulous idea of nucleic acids as the primary substance of biological inheritance.

[4] Understanding the Concept of Molecular Biology (With Diagram) — The basic concept of molecular biology is to investigate the activities of an organism's makeup at a sub-cellular level. The focus is on the sequence of the DNA (the genes), the rate and timing of the expression of those genes, the mechanisms involved in expressing those genes, and the effect that they have on the whole cell and ultimately the whole organism.

[188] Ethics, Values, and Responsibility in Human Genome Editing — Citation PDF Altmetric CRISPR/Cas9 genome editing is an inexpensive and efficient tool to introduce changes in DNA. Its ease of use sets virtually no limits on potential scientific and clinical applications. Genome editing at the beginning of embryonic life means that any genomic alteration introduced will pass on to the germline and propagate through future generations. These possibilities have sparked considerable debate about germline genome editing ethics, governance, and the scope of responsible use of germline interventions.4 An announcement by Chinese researchers in April 20155 that they had edited human embryos initiated public controversy and fear about germline genome editing.6 In November 2018, He Jiankui announced the birth of twin girls with a modified version of the CCR5 gene,7 an alteration that could confer resistance to HIV infection. It has been argued that ethics and governance debates should go beyond the imperative of clinical innovation by paying attention to respect for human rights11 and dignity12 and by carefully considering unknown consequences for gene-edited people and future generations, both in terms of safety and possible eugenic uses of this technology.13 Others have pointed to the availability of safer and more ethically acceptable means of preventing congenital genetic defects, such as pre-implantation genetic diagnosis.14 Still others fear that, if anything goes wrong with human germline editing, research on and clinical use of somatic cell therapy could face reputational crises.15 Consensus has gradually emerged in the scientific community about the need for an international moratorium on premature clinical uses of human germline editing.16,17,18 Public dialogue aimed at reaching “broad societal consensus”16 on uses of genome editing has also emerged as key to the legitimacy of governance decisions about such controversial technology.19 Given that the first clinical trials involving somatic uses of CRISPR/Cas9 are underway,20,21 genome editing is primed to foster dramatic innovation in patient care provided that it is used responsibly.

[189] What are the Ethical Concerns of Genome Editing? — Most of the ethical discussions related to genome editing center around human germline because editing changes made in the germline would be passed down to future generations. Overview The debate about genome editing is not a new one but has regained attention following the discovery that CRISPR has the potential to make such editing more accurate and even "easy" in comparison to older technologies. As of 2014, there were about 40 countries that discouraged or banned research on germline editing, including 15 nations in Western Europe, because of ethical and safety concerns.3 There is also an international effort led by the US, UK, and China to harmonize regulation of the application of genome editing technologies. Researchers and ethicists who have written and spoken about genome editing, such as those present at the International Summit on Human Gene Editing, generally agree that until germline genome editing is deemed safe through research, it should not be used for clinical reproductive purposes; the risk cannot be justified by the potential benefit. Researchers and bioethicists also worry about the possibility of obtaining truly informed consent from prospective parents as long as the risks of germline therapy are unknown.10 Justice and Equity As with many new technologies, there is concern that genome editing will only be accessible to the wealthy and will increase existing disparities in access to health care and other interventions.
