Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Proteins carry out many of an organism's critical functions, and they are coded for by genes. To make a protein from a gene, a cell first needs a copy of the gene in the form of a molecule called RNA.

By examining genomic variation more closely, scientists can now identify new disease connections with greater speed and accuracy. For centuries, scientists have recognized that certain illnesses can ...

The development of DNA-/RNA-based drugs, like COVID-19 vaccines, is exploding. Current methods are costly, but researchers are finding effective and inexpensive method for producing stable, modified ...

Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life.

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

“Our findings show that RNA-based testing can uncover hidden risks in multiple myeloma that DNA tests alone miss,” study ...

Francesca Storici consults at Tessera Therapeutics. She has received funding from the National Institutes of Health and the National Science Foundation. Your DNA is continually damaged by sources both ...
