New 3-D model shows how proteins bind to DNA packagesKatherine Harmon
How does DNA encode the information for a protein? There are only four DNA bases, but there are 20 amino acids that can be used for proteins. So, groups of three nucleotides form a codon that specifies which of the 20 amino acids goes into the protein. A 3-base codon yields 64 possib...
How is DNA information used to make proteins? When is DNA duplicated? How are primers involved in the replication of DNA? What process do cells use to make copies of their DNA? When does the replication of DNA occur? How do RNA viruses replicate?
What Does DNA Do? Where Do We Get Our DNA? Deoxyribonucleic acid, or DNA, is a molecule containing instructions on how to make a living organism. Its structure and sequence instruct the cell on how to make proteins, which go on to carry out important functions of a cell. Many cells for...
During transcription, the first step in reading the gene's directions and getting proteins made, the nucleus of the cell needs to figure out how to get its knowledge transferred. It does this by copying itself and sending the copy off to share the directions. This is like you copying out ...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
How is DNA methlyated and demethylated? How does DNA unfold itself in space during reproduction? How is DNA information used to make proteins? Explain how DNA is packaged or organized within the cell. How is the eukaryotic DNA packaged? Explain. ...
How does CRISPR edit DNA? Researchers have taken advantage of the CRISPR system's ability to make precise cuts in DNA. Byadapting CRISPR to make desirable genome editsin any cell type, researchers can alter genes or DNA sequences that regulate genes' activity, changing their function or express...
” Roman Zubarev, a professor at Uppsala University, says that a combination of methods is necessary to fragment proteins of interest to the desired degree: “In my opinion, the bottleneck is the absence of high-quality fragmentation techniques. Collisional activation alone does not deliver full ...
Normally, immune cells called T-cells recognize and attack cancer cells. Lung cancer cells sometimes make proteins that help them "hide" from T-cells. Checkpoint inhibitors essentially reactivate the immune system, freeing it to attack the cancer. ...
