this structure is called the coding strand. The second strand that lies below the coding strand is called the template strand. In order for a RNA polymerase to go from the upper strand to the second strand it must go through the process called transcription. First‚ the RNA polymerase must attach on to one of the genes on the coding strand on DNA. Once the RNA polymerase attaches‚ it must then begin the process called initiation. This means that the RNA polymerase opens up both strands of DNA in order

Biology‚ 7e (Campbell) Chapter 16: The Molecular Basis of Inheritance Chapter Questions 1) For a couple of decades‚ biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins‚ and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because A) proteins have a greater variety of three-dimensional forms than does DNA. B) proteins have two different levels of structural organization; DNA has

receptor is made that enters the cells nucleus reacting with the DNA‚ in desire for the expressed gene. Expression is complex process upon which there are many steps which undergo. One is transcription. This is where a copy of one side of genetic information is made to be stored in DNA. Upon starting transcription‚ proteins are made to read the DNA called rRNA. A second process is involved called splicing. This is where unnecessary parts of RNA are made to create the gene the protein has sent out to

In the past‚ people probably dictated your reports for a transcription department just like almost every other physician did. However‚ with the advent of EHR‚ most systems have allowed hospitals to practically eliminate transcription altogether. Physicians instruct many medical terms or office managers to indicate that treatments or services were provided that were not. These errors add up over

protein domain known as the homeodomain. Hox genes produce protein products belonging to a class known as transcription factors. Transcription factors are capable of binding to DNA‚ in which they regulate the transcription of genes. This homeobox sequence codes for a 61 amino acid helix-turn-helix protein‚ resulting in the homeodomain. The homeodomain acts as a switch that turns the gene transcription on and off by binding to specific sequence enhancers of a gene that either activates of represses the

Why would the closure of a potassium channel in the presynaptic axon terminal change the amount of Ca2︎ entering and change the amount of neurotransmitter released? Serotonin(5-HT) receptor on the sensory axon terminals is a G-protein-coupled metabotropic receptor. Stimulation of this receptor leads to the production of intracellular second messengers‚ cAMP‚ which
