Sequence

Epigenetics studies the heritable modifications affecting gene expression that are produced without changing DNA nucleotide sequence of the organism. The ancient origins of the term "epigenesis" date back to Aristotle, which described this phenomenon, scilicet each organism is gradually originated from an undifferentiated mass by a series of steps during which new parts are added, in contrast with the preformistic theory that organisms developed from versions in miniature of themselves. The…

big bang as well as God, because that would prove that the universe has got a beginning. Another principle of the kalam argument is that there needs to be a self-causing necessary being (God), because there needs to be a prime mover to start the sequence of events. This supports the idea that God was the first cause of the big bang. This argument supports the existence of God because he is the self-causing necessary being. The only adequate explanation, the arguments suggest, is that it was…

off beats. Another thing which links my composition to the reggae style was the instruments I used. Firstly, one of the prominent aspects of reggae music is bass. It is played in low-frequency to emphasize the bass sound. I used riff which is a sequence of notes in a small number of bars that can be repeated to get a solid ground on the creation of my composition. Secondly, I used the piano for modulation and to follow one of the areas of study which informs me to use the primary chords and…

I learn to make it easier to take in knowledge is a great help for my future classes. According to “Intentional learning for college success” I am a dynamic learner. My LCI score is Technical Reasoning (28), Precision (23), Confluence (23), and Sequence (22). I believe for my personality and the way I use my learning patterns that I…

Target article: Green, R.E., Krause, J., Briggs, A.W., Maricic, T., Stenzel, U., Kircher, M. et al. (2010). A draft sequence of the Neandertal genome. Science, 328, 710-722. This study created a draft sequence of approximately 60% of the Neanderthal genome based on nucleotides from three individual Neanderthal samples (Vindija Neanderthal fossils Vi33.16, Vi33.25 and Vi33.26). The study differs from previous attempts to examine Neanderthal DNA as it examines mitochondrial DNA, Y chromosomal…

proteins, chains of amino acids, are also called polypeptides. Proteins’ structures have four levels of organization. The primary structure consists of amino acid sequences, which determine the structures and functions of the proteins. Amino acid sequence for each distinct protein is different and for all molecules of the same proteins the sequence is the same. The secondary…

Plant proteases with excellent catalytical properties perform many functions in biological systems. Vallaris solanacea, a new plant protease has been identified and screened effectively for its caseinolytic activity. This protein activity was specifically inhibited by p-chloromercuribenzoate, which showed that it is a cysteine protease. Preliminary investigations such as effect of pH and temperature on the caseinolytic activity of crude protease were done. Stability towards temperature and pH…

Polymerase chain reaction (PCR) Generalities PCR is a method developed in 1985 by Kary Mullis and to obtain, by coupling a heat-resistant DNA polymerase and without cloning, amplification of a fragment of DNA known. Initially, DNA polymerase was isolated from a bacterium thermophilne (resistant to significant increases in temperature), as Thermus aquaticus (Taq polymerase). Currently, we use recombinant enzymes, whose; elaboration is easier and greater efficiency. The general principle of PCR is…

In this lab, the guiding question is “How does the surface tension and relative intermolecular forces compare between certain substances?” In order to fully understand this guiding question, we have to know what is the surface tension and intermolecular force. The definition of surface tension is “the inward force, or pull, that tends to minimize the surface area of a liquid, and the definition of intermolecular force is the force, or pull, between the molecular which has polar…

Protien Synthesis DNA is our genetic material. Since DNA is stuck in the nucleus it has to get out somehow, but it can't, so what does it do then? The answer to that, is that DNA makes a copy of one of its helixs to get out of the nucleus. The process of DNA making a copy of itself is called transcription. The copy of the DNA is called mRNA and that is the messenger type of RNA. The DNA makes a copy of itself called mRNA, then gets out of the nucleus and leaves to attach itself onto a ribosome.…
