GRT1 Biochemistry Task 1

DNA Replication at the Biochemical
Level
• A DNA (Deoxyribonucleic Acid) molecule is in comprised of two strands of nucleotides.
• When DNA replicates, the nucleotide strands are split and used as a template for a new strand.
– The original strand (template) is called the parent strand
– The replicated strands are called daughter strands.
– A complete daughter DNA strand contains one strand from the parent, and one strand that has been added as a match for the template.

• Because the daughter strands each contain one strand of the original DNA, this process is semi-conservative.
(Wolfe, 2000c)

Role of mRNA
• Transcription begins within the nucleus of a cell when mRNA binds to a segment of DNA and produces a copy.
• This mRNA moves out of the nucleus and into the cytoplasm. • Once in the cytoplasm, the mRNA is able to become a part of the process of translation.
• Codons in single strands of mRNA join with anticodons of tRNA (transfer RNA) to form proteins. (Wolfe, 2000a)

    Room 362, a 48-year old married male, was admitted to Lynchburg General Hospital after showing symptoms of hepatic failure. He had a chief complaint of weakness and drowsiness displayed by the inability to be easily awoken by his wife, which led to his admission into the hospital. He has been diagnosed with hepatic failure demonstrated by laboratory testing and an arterial blood gas (ABG) analysis. Hepatic failure is a condition caused by a sudden or chronic illness, which results in irreversible damage to the liver ultimately inhibiting the liver’s functional abilities. Room 362’s hepatic failure was most likely a result of his alcoholic cirrhosis and hepatitis C. Room 362’s history with alcohol abuse and smoking led to his current state of…

    In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate, an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1, we observed the basal rate of three different worms, and then placed the same three worms on different concentrations of caffeine and nicotine. “Caffeine is known to act as an inhibitory neurotransmitter in the brain; it promotes sleep and suppresses aurosal, binding to the adenosine neurotransmitter receptor to block its inhibitory action” (CCNY lab manual, 2014). Before our experiment was conducted we hypothesized that increasing the concentration of caffeine will increase the pulsation rate. During this experiment we used 1.0mM, 3.0mM, and 10.0mM concentrations of caffeine. The highest the concentration the more effect it would have on the pulsation rate, so in this case we could assume that 10.0mM would have the highest effect on the pulsation rate of the blackworms.…

    In understanding the biochemical prospective of DNA polymerase in replication, its important to understand the structure of DNA and the machinery behind it. The structure of DNA provides a template-driven mechanism for its replication. Experiments by Meselson and Stahl showed that each polynucleotide strand serves as a template for a daughter strand. On completion of replication, each daughter strand, which is hydrogen bonded to its template, or parental strand, segregates to one of the daughter cells. This mode of DNA replication is called semiconservative DNA replication.…

    The second strand is built by having a polymerase jump ahead on the strand and fill in the complementary nucleotides backwards. This strand moves in the outward direction, hence away from the replication fork. The DNA polymerase for this strand starts a burst of synthesis at the point of the replication fork. The addition of nucleotides to the 3` end of a short new chain until this new segment fills in a gap of 1000 to 2000 nucleotides between the replication fork and the end of the growing chain to…

    Biochemistry is a very interesting subject to study and eventually work in. From studying microorganisms to creating medicine to prevent alien viruses from infecting people, it has always been a fascinating subject to me. I became interested in this career because I was always interested in the science field. Ever since I was young, I always liked to experiment with different things. I found out about biochemistry by my chemistry tutor. In the first semester, I struggled with chemistry so I called him over to help me. My tutor is an undergraduate at the California State University of Long Beach with a pursuit of a Secondary Education Credential in Chemistry. He informed me about the field of biochemistry and why this field will be extremely helpful in the future generations.…

    We can also say that; Transcription is the mechanism by which the base sequence of a section of DNA representing a gene is converted into the complementary base sequence of mRNA. For this to happen, the DNA double helix structure unwinds hence exposing the inner bases. Out of these two strands , one of them is selected against which the complementary single strand of RNA forms , this strands is termed as the ‘template’ strand i.e. the strand that is actually transcribed…
