11 questions tagged Biotechnology — spanning every one of the seven Ws.
When was the first mammal cloned?
The first mammal cloned from an adult somatic cell was Dolly the sheep, born in 1996. Her existence was announced in 1997.
When was the first CRISPR gene-editing breakthrough reported?
CRISPR-Cas9 was adapted for programmable gene editing in 2012, making it a modern genetic breakthrough.
When was the first successful trachea transplant performed?
A landmark trachea transplant was performed in 2008. It used a decellularized donor trachea seeded with the patient’s own cells.
When was the first bird extinct in modern times to be revived through de-extinction science?
No bird has been de-extincted yet, though modern de-extinction work has been actively discussed and pursued in the 21st century.
When was the first successful cloning of an amphibian achieved?
A famous early amphibian cloning breakthrough occurred in 1952, when nuclear transfer experiments were carried out in frogs. These studies became a landmark in developmental biology.
Where is the genome project map of human genes based?
The Human Genome Project map is based on the chromosomes in the cell nucleus. It produced a reference sequence of the human nuclear genome, with mitochondrial DNA mapped separately.
Whose research created the first cloned mammal?
Ian Wilmut and his team created Dolly the sheep in 1996 at the Roslin Institute in Scotland. Dolly was the first mammal cloned from an adult somatic cell.
Whose research first led to CRISPR gene editing?
Jennifer Doudna and Emmanuelle Charpentier turned CRISPR-Cas9 into a gene-editing tool. Their landmark paper was published in 2012.
What is a monoclonal antibody treatment?
A monoclonal antibody treatment uses lab-made antibodies designed to bind one specific target. It can be used to prevent or treat some infections and diseases.
When was the first successful mammal cloning achieved?
The first successful cloning of a mammal was in 1996, when Dolly the sheep was born.
When was the first bacterial species genetically engineered for useful protein production?
Genetically engineered bacteria were developed in the 1970s, and by 1978 they were being used to produce human insulin. This was one of the first major biotechnology successes.
