Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...
Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded ...
Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it ...
tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...
Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but cannot simply accumulate inside the cell forever. Once they have done their ...
This image highlights two alternatives for the ribosome to be recruited to an mRNA that is still being synthesized by RNA polymerase (RNAP). RNAP (left, red) can directly deliver the mRNA to the entry ...
Biomedical engineers at Duke University have demonstrated a new synthetic approach that turbocharges bacteria into producing more of a specific protein, even proteins that would normally destroy them, ...
Oligonucleotides are short strands of DNA or RNA that play a major role in drug discovery and molecular diagnostic chip technology. They are used from initial research and screening through to target ...
