How are mutations caused in DNA replication? What happens during DNA replication? What happens second during DNA replication? Why is DNA replication bidirectional? How is DNA microarray efficient? How does DNA ligase work? How do the different DNA nucleotides pair during DNA replication?
How are mutations caused in DNA replication? How do retroviruses work? Explain the concept of jumping genes in prokaryotes with examples. How is DNA polymerase made? How does DNA direct protein synthesis from inside the nucleus? How is transcription similar in bacteria and eukaryotes?
In reality, most genes are hundreds of times longer. Credit: Thomas Splettstoesser/Wikipedia/CC BY-SA 4.0 Scientists have demonstrated how a mutation in a specific protein in stem cells causes an incurable premature aging disease called dyskeratosis congenita, and were able to introduce the ...
"C9ORF72 mutations are by far the most common genetic defect associated with both ALS and FTD, so understanding how the mutation causes disease is tremendously important for efforts to develop therapies to stop or reverse the death of neurons in the brain and spinal cord of patients," said co...
Scientists have identified a neurodevelopmental disorder, caused by mutations in a single gene, that affects tens of thousands of people worldwide. The work, published in the May 31 online issue ofNatureMedicine, was conducted by researchers at theIcahn School of Medicine at Mount Sinaiin collabora...
In this case, the dominant model58 predicts that separate male- and female- sterile mutations on the same chromosome cause the shift from hermaphroditism to dioecy through an intermediate phase of gynodioecy. Once these mutations have occurred and reached sufficient frequency in the population, ...
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.

"We've known whatmutationsare involved for some years, and the set of outcomes that result, but, until now, we've not known how one leads to the other. This new research shows us how each of these diseases can be caused by the same underlying cellular pathway." ...
DNA mutations are when the identity of a nucleotide changes during the lifetime of an individual or during the creation of new DNA in advance of cell division. Typically, every time the cell divides, the DNA sequence is faithfully copied from the mother cell to ...
