There are 4 pairs of proteins (histones H2A, H2B, H3 and H4) involved in forming the protein core for the DNA to coil around. The DNA strand wraps twice around the core and continues to the next nucleosome. H1 histone protein links the nucleosomes to each other. Nucleosomes then coil tightly to form chromatids which are tightly condensed to form a full chromosome. This gives the chromatin a beaded appearance under an electron
What is the difference between Biochemistry and Molecular Biology? Biochemistry is covered with proteins, their structures and how they interact with each other. It is concerned with structure and function. Biochemists deal with shape and location of a protein which decide its function. Your eye has a certain shape and arrangement that allows it to function as an eye -this is what Biochemists
PHYSIOLOGICAL DISTRIBUTION: These lipase enzymes have a widespread biological activity in biological processes from usual metabolism of dietary triglycerides to signalling pathways and inflammatory mechanisms. Thus they are both intracellular and extracellular. 1. Lysosome cell organelle has
Those molecules become excited and having been inspired with energy due to the impact. The free electrons return to their normal state very quickly and release extra energy in form of light. As the light is emitted, the lampshade which covers the bulb will soften the light from the light bulb and reduce the glare. The lampshade also focuses the light from light bulb in a desired
We are only able to see due to the fact that light from an object travels from the said object and into our eyes.When a ray of light passes through different mediums, it changes both the velocity of the light ray and the direction.This is called the refraction of light rays. This is due to the fact that different substances have different optical densities. The light will travel slower through a substance that is very optically dense and faster through one that is less dense. The refraction of a ray of light only occurs at the boundary line and light rays always travel in a straight line. Refraction does not occur when the object is at an angle of 90 degrees and only occurs when the object is tilted.
Now, if you do this same shot again but you angle the que ball a to strike the other ball at an angle then the que ball is going to bounce of in a new direction at a slower pace then the initial photon but faster then the straight on shot because it didn’t transfer as much energy to the other ball. Which means that the other ball isn’t going to travel as far and the chance of it interacting with another ball is going to decrease because it doesn’t have enough energy to go a great distance. In addition, the energy of the initial photon can be calculated by the equation Ei = Es + Eb + Eke. Es is the energy of the scatter, Eb is the energy of the bonded electron that was ejected, Eke is the kinetic energy of the electron, and Ei is the energy of the incident electron. In order for the incident photon to knock out the electron from it’s binding shell the energy needs to be greater in the incident photon then the bonded electron.
The central dogma of modern biology is that DNA gets transcribed into a transportable compound that’s composed of mRNA. The mRNA then synthesizes a particular protein or group of small proteins. Genes made up of proteins, give a set of instructions for a function that a molecule needs to do in the cell. An epigenome is a compound that sits on DNA and controls your gene expression. The central dogma of modern biology is related to epigenetics because the environment can influence which genes are expressed and which are not or how much a gene is expressed.
De Cock and associates (2004) examined the spectral characteristics of the larvae of three Belgian species of fireflies. The study focused on the importance of light emittance, which is used for courtship signals. The bioluminescence shows sexual dimorphism, place of activity, and the discrimination of conspecific signals. Based upon the findings, females display a more exact method of bioluminescence than the males. In addition, the larval and adult females displayed the same range of
