Briefly describe what you know about the structure of DNA and how DNA is packaged in a cell. How is DNA information used to make proteins? What is the biochemical structure of DNA and how does DNA replicate? Summarize the structure and function of DNA. What does it mean that DNA conta...
The information in DNA: guides the cell (along with RNA) in making new proteins that determine all our biological traits gets passed (copied) from one generation to the next The key to all of these functions is found in the molecular structure of DNA, as described by Watson and Crick. ...
How does DNA replicate itself? Explain about DNA structure. Describe the structure of chromatin. How does the DNA in animal cells look like? How do the proteins of the transcription machinery access DNA that is tightly associated in chromatin?
New Study Uncovers Unexpected Change In DNA Organization To turn genes in DNA "on" and "off," enzymes in cells must interact with nucleosomes, which are complexes containing proteins that allow cells to organize their DNA. One such enzyme, Dot1L, is mutated in mixed lineage leukemia, a form...
It occurs when a reverse transcriptase enzyme synthesizes DNA from an mRNA template and the DNA is then integrated into the genome. Because retrotransposition usually uses mature mRNAs as a substrate, the resulting duplicate genes often lack introns. Degree distribution The degree of a node in a...
The Polycomb group (PcG) and Trithorax group (TrxG) proteins can confer long-term, mitotically heritable memory by sustaining silent and active gene expression states, respectively. Several recent studies have advanced our understanding of the molecular mechanisms of this epigenetic memory during DNA ...
Proteins are the drivers of life in a cell—they’re responsible for carrying out all of life’s functions. They are created through a process called protein synthesis, which relies heavily on DNA. Why is DNA so important in protein production? Because it houses all the information a cell ...

Salk scientists studying plants discovered a small family of proteins that control where in the genome DNA methylation marks are added. Their work on this aspect of genetic regulation is highly relevant for processes that range from normal development to cellular defects and diseases, which can arise...
DNA transcription- DNA is transcribed into an RNA message for protein synthesis. The three major steps are initiation, elongation, and finally termination. DNA translation- The transcribed RNA message is translated to produceproteins. In this process, both messenger RNA (mRNA) and transfer RNA (tRN...
