Protein synthesis is important because it creates new proteins for the cell. Proteins are important because they catalyze chemical reactions, create structures, and allow for cellular communication.Answer and Explanation: DNA controls protein synthesis by storing the genetic code for all proteins. The ...
How Cells Work Proteins A protein is any chain of amino acids. An amino acid is a small molecule that acts as the building block of any protein. If you ignore the fat, your body is about 20-percent protein by weight. It is about 60-percent water. Most of the rest of your body is...
The article discusses a research by Zhe Liu and colleagues at Howard Hughes Medical Institute in Ashburn, Virginia published in the periodical "Cell" of 2014 issue related to the proteins, transcription factors binding to specific genes to regulate their activity in mouse embryonic stem cells....
DNA Structures DNA is made of subunits called nucleotides. A “subunit” is a subdivision of a larger unit. For example: a subdivision you live in is a smaller unit of a city or town. It takes many subunits working together to make up a whole, functioning unit. Nucleotides are the subun...
A gene is simply a template for a protein, and often these proteins are enzymes. An enzyme is a protein that speeds up a particular chemical reaction. For example, one of the enzymes in an E. coli's DNA might know how to break a maltose molecule (a simple sugar) into its two ...
How is PCR different from DNA replication? How are nucleotides added in DNA replication? How does RNA participate in DNA replication? How does DNA sequencing work? How do proteins assist in DNA replication? How does DNA replication end?
A host of proteins and other molecules sit on the strands of human DNA, controlling which genes are read out and used by cells and which remain silent. This aggregation of genetic material and controlling molecules, called chromatin, makes up the chromosomes in our cell nuclei; its control ove...
Unfortunately, these agents face a difficult hurdle. The raw material (amino acids) and the factory (ribosome) required to build the machines (proteins) are both found outside the HQ (nucleus). That may not initially seem like a problem, as the DNA could simply be taken outside the nucleu...
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 or
"Although these two groups of helper proteins were previously thought to function independently, our study shows that they actually work together to activate Rad51 in DNA repair," explains senior author Hiroshi Iwasaki, Professor at the Tokyo Institute of Technology. "The fundamental mechanisms of DN...
