I want to start this post by saying I’m sorry. I’m sorry to have been absent for a while now,Forgive me but here is the reason. Have you ever wondered how humanity came to exist as it is today ? I’m pretty sure you have . Evolution is complex. One way to explain it simply is just ‘trying to get better’. You evolve to live better, longer and happier. Paper Title: How culture shaped the human genome : Bringing Genetics and the Human Sciences together What it really means: We live in a constant cycle of change between who we are (genetically/culturally) and where/how we live. It has been suggested that evolution of humans occurs mainly due to the need to live and look for drier and cooler habitats. It’s also been suggested
The dictionary defines emotion as ‘instinctive or intuitive feeling as distinguished from reasoning or knowledge’ or ‘a strong feeling deriving from one’s circumstances, mood, or relationship with others.’ Emotion is absolutely vital to human behavior and during the course of our lives, most, if not all of our actions are determined as a result of our emotional states. Importantly, although pretty much everybody would go ‘aawwww’ after watching cat videos on Youtube, I think it’s fair to say that we different emotional beings. These differences in emotionality mainly arise due to the variations in the neural (nerves) systems recruited to process the stimuli that trigger emotion. While significant advances have been made to study brain circuits that process these stimuli, the paper I am presenting here today focuses on the advances
To do great things is difficult; but to command great things is more difficult. —Friedrich Nietzsche What makes a great leader? This is an age old question that has been studied and analyzed for ages- from the battlefields of Waterloo to the booming capitalism of Wall Street in America, us humans are always on the lookout for leaders to aspire to. The greatest of leaders have the capacity to mould and shape events in an unprecedented manner. Therefore it seems pertinent to try and figure out what makes a Napoleon, a Gandhi or a Steve Jobs tick. Obvious factors that contribute to the software and hardware of a leader are things such as upbringing or values and intelligence. There is one other factor that could contribute to qualities of leadership…DNA.
Simple Version : How do cells manage to transcribe DNA into RNA? For this to happen one major machine needed is called the RNA polymerase, which is big protein complex that is able to read and recognize certain sequences of the DNA to which it can bind. It also has the capacity to polymerize ( generate a chain) nucleotides to create the RNA. Once it reaches a Stop Sign in the DNA (called a Hairpin Loop), the polymerase detaches and the RNA is released. It’s important to know that there is a regulatory region on the DNA in front of the Genes. This region is where other factors will influence the transcription of the genes either positively or negatively. Extremely Simple Version : Imagine your Gene has a tag ( TATAA). This tag can be read by laser
Here is an excerpt from Matt Ridley’s book ‘Genome’. Essential reading for anybody who wants to understand what DNA is and what goes on in our cells! Here he is simplifying the Human Genome for us- “Imagine that the genome is a book. There are twenty-three chapters, called CHROMOSOMES. Each chapter contains several thousand stories, called GENES. Each story is made up of paragraphs, called EXONS, which are interrupted by advertisements called INTRONS. Each paragraph is made up of words, called CODONS. Each word is written in letters called BASES. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this one, or as long as 800 Bibles.If I read the genome out to you at the rate of one word per
