During this process, each unique DNA molecule in the library is bound to the surface of a bead or a flow-cell and PCR amplified to create a set of identical clones. In the case of Ion Torrent technology, a process called “templa...
This original cell was likely little more than a sac of small organic molecules and RNA-like material that had both informational and catalytic functions. Over time, the more stable DNA molecule evolved to take over the information storage function, whereas proteins, with a greater variety of ...
What makes one DNA molecule different from another? Which organelles of a cell possess their own DNA? How does mRNA differ from DNA? How does RNA differ from DNA in structure? What two cell division processes use DNA replication? Chromatin contains proteins called How are DNA replicati...
New module: Molecule Cloud View The "Molecule Cloud View" module allows you to visualize a group of molecules as their respective van der Waals surfaces within 3D datasets, specifying their positions and orientations. To use this feature, you need a molecule template, such...
this, a DNA molecule is cut into smaller pieces and then used as a template for a particular strand of RNA that has been copied from the DNA’s matching complementary strand. This RNA is then able to match up with each piece of DNA and can be read off slowly, one letter at a time...
What does RNA primase do in DNA replication? Which molecule is responsible for the sequence of nucleotides in an RNA molecule? A: the hydrogen bonding between purines and pyrimidines B: the complementary sequence of amino acids C: the complementary sequence in DNA D: The directionality of nu...
A phospholipid is a large molecule synthesised within cells (biomacromolecule) that contains two nonpolar hydrophobic, fatty acid tails, joined to a hydrophilic head which contains phosphate. Structure: A scientific model: Cell membranes are phosphate bilayers ➔ 2 layers of pho...
As a cell prepares to build a new protein, its DNA unzips to expose one strand of the gene with the instructions to build said protein. Then, an enzyme zooms in and constructs a new RNA molecule whose sequence mirrors that of the unzipped gene. This RNA copy, called messenger RNA (mRNA...
What is the structure of the DNA molecule, and what do we mean by antiparallel? What are double-stranded RNA viruses? What do we refer to a single piece of coiled DNA ? How does the double-helical structure of DNA relate to its function? Why is the...
The active site of an enzyme is a small portion of the enzyme molecule. What is the function of the rest of the large molecule? What two models are used to describe the way enzymes interact with substrates? What role does an enzyme play in the human body? What are enzymes and what...
