The identification of RNA as the crucial missing link between DNA and protein was subsequently confirmed by cell fractionation experiments, in which the different parts of cells were separated and ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

When we see pictures of chromosomes ... Chromatin refers to proteins that help organize the long DNA molecule. The protein shown here supports and organizes small loops of DNA.

In the pursuit of understanding the pathogenic expression mechanisms of bacteria and the advancements in biofoundry ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer.

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA.

the Cas9 protein hooks up with the guide RNA and then moves along the strands of DNA until it finds and binds to a 20-DNA-letter long sequence that matches part of the guide RNA sequence.
