Epigenetics is the series of chemical modifications of DNA and its connected proteins that contain phenotypic information during cell division. These modifications alter gene expression without changing DNA sequence. They differ among tissues and change over throughout the organism’s lifetime. A well-understood example of epigenetic modification is DNA methylation‚ the process by which a methyl group is covalently bonded to cytosine. During DNA replication‚ a specific enzyme recognizes unmethylated

During my junior year‚ I was required to write a synthesis essay about a topic of my choosing. As a woman considering a career in science‚ I researched the gender bias in the science field‚ and why it’s so apparent today. I didn’t realize that I would uncover article after article of individuals undermining the female gender. Ivy League Presidents‚ men with doctorates in Biology‚ and individuals with no background in science alike spread false and harmful information about women. After

Effects of Differentiation on Enzymatic Activity Introduction HL-60 cells are capable of undergoing differentiation to induce different cell types. HL-60 cells can undergo morphological changes‚ changes in gene expression‚ and changes in protein synthesis. In the past weeks‚ we were able to conclude that HL-60 cells treated with DMSO and HL-60 cells treated with PMA will differentiate into granulocytes and monocytes upon treatment (1). We were also able to observe that both types of treated cells

Mechanism of chalcone formation Kinetic studies have been reported for the base-catalyzed formation of chalcone and its derivatives. [7‚ 8‚ 9] Two alternative mechanisms have been advanced for the reaction of benzaldehyde with acetophenone in the presence of a basic catalyst. 5 The formation of chalcone by the acid catalyzed condensation of acetophenone and benzaldehyde has been studied [10]. The following mechanism seems to be operating- 6 Importance of chalcones [1]They have close relationship

"My house has been destroyed multiple times‚" is the quotes of people who have been affected by tornadoes and hurricanes each year. At up to 150 m.p.h. (Source 4)‚ hurricanes are deadly‚ and definitely with tornadoes who sweep in at a whopping 300 m.p.h. (Source 3)! These storms are life-threatening! Their characteristics‚ cost and damage‚ and their formation have a lot to do with their danger that can approach on you when you least expect it to. If you live in a mid-western state‚ you may be in

Many people in this generation would label themselves as poor‚ but sometimes the line between each class is misunderstood and blurred due to wants instead of needs. Believe it or not there are different levels that describe the underprivileged. Poverty can be divided into about five diverse subgroups‚ which are transitional‚ marginal‚ residual‚ absolute and relative (Carl‚ Page 30). No matter which description of poverty a person may fall into the effects of this social class can be great. A life

TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases‚ Transcription is located in the Nucleus‚ and the only type of RNA that is involved in Transcription is mRNA‚ and the purpose is so that the code can get out of the Nucleus‚ mRNA is also made through Transcription‚ It also takes information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine

synthesised is only 67%-70% and a maximum 70% yield of ester usually is not considered to be acceptable for a synthesis reaction‚ instead it is considering as a poor yield of ester. The synthesised ester can only have a maximum yield of 70% because for ester in which the carboxylic acid and alcohol are sterically unhindered‚ a same ratio mixture of carboxylic acid and alcohol can only synthesis ester with a maximum yield of 70% ester as the reaction with the same ration of mixture will reach a state
