The Curious Case of CRISPR-Babies
“Chinese scientists had used CRISPR-like tools to edit the live embryo. By editing germ cells they had produced genetically altered babies and who are known as CRISPR-babies.” The story of…

“The MTHFR gene encodes an enzyme known as methylenetetrahydrofolate reductase that breaks down homocysteine amino acid. C677T and A1298C are two common mutations of the MTHFR gene.” Enzymes are proteins…
Continue readingWhat is a Marker Gene?
“A marker gene is a known DNA sequence located nearer to the target gene with detectable and inherited properties.” Marker genes are applicable in the genetic engineering experiments, especially in…
