Tanner Rackow DNA Assignment The scientists Oswald Avery, Colin MacLeod, and Maclyn McCarty all contributed to proving that DNA is genetic material. In their experiment involving treptococcus pneumoniae, the bacteria that causes pneumonia, they observed a factor which they called the “transforming principle.” Mice were injected with a harmless version of the bacteria as well as an inactive lethal form. Despite the predictions of the mice remaining healthy, the mice soon succumbed to disease and

Epigenetics What is epigenetics? Epigenetics refers to external modifications to DNA that turns genes "on" or "off". The DNA sequence is not changed, these modifications just affect how the genes are read. Epigenetic regulation involves the modification of DNA and the proteins associated with DNA, which results in changes to the conformation of DNA without a change in its sequence. In some cases, epigenetic modifications are stable and passed down to future generations, but in others cases they

protein or nucleic acid. In other words, the process of producing proteins is irreversible: a protein cannot be used to create DNA. The dogma is a framework for understanding the transfer of sequence information between sequential information-carrying biopolymers, in the most common or general case, in living organisms. There are 3 major classes of such biopolymers: DNA and RNA (both nucleic acids), and protein. There are 3×3 = 9 conceivable direct transfers of information that can occur between

Humans share about 99% of our DNA with chimpanzees and bonobos. DNA (deoxyribonucleic acids) is the molecule that makes up an organism’s genome. DNA is located in the nucleus of eukaryotic cells and is found in the nucleoid of prokaryotic cells. DNA consist of genes which are instructions to make molecules called proteins. DNA’s serves a significant purpose to any organism it holds the instructions that is required for an organism to grow, survive and reproduce. DNA is now used by scientist to test

have criminal sanctions, sentencing practices, types’ of punishment, imprisonment, and death penalties. The question I present is what about all those whom have been wrongfully convicted, sentenced and then later on exonerated based upon DNA or whatever evidence available? What about the various countries whom have taken the act in an attempt to exonerate those individuals especially here within the United States? I believe that the wrongly accused deserve to not only be exonerated from their sentence

physical traits, such as muscularity, gender and some have an extra Y chromosome, these children were also at a higher risk of committing crime. Therefore the late Hernstein argues, it’s refutable that criminal behavior has a genetic source. All evidence points to behavior such as aggression which can possibly be inherited. Some individuals may be predisposed and more at risk of developing criminal behavior than the average due to some biological difference. If in fact this difference is heritable

1. Write an essay on protein structure and synthesis Protein synthesis is a cellular process leading to the production of proteins. This term is also synonymous to protein translation. It begins with a sequential process of transcription of DNA into mRNA, which is then used as input for translation after exon-intron splicing. The addition of successive tRNA molecules based on the code of mRNA matched up by base-pairing through their anti-codons in the ribosomes creates the nascent protein. After
