Cellular Metabolism Essay

3.1 Cellular Metabolism:

Deoxyribonucleic Acid (DNA) is replicated when enzymes begin to unzip the DNA. The enzymes do this by breaking the hydrogen bonds that are between the pairs. After this occurs, the unpaired bases are now free to bind with other nucleotides. They may only bind if the nucleotides have the appropriate complementary bases. DNA polymerase now attaches DNA nucleotides to one end of the growing strand of nucleotides. Now there are two DNA molecules, each has an original nucleotide strand beside the new strand. The two molecules are now identical to each other(McGraw-Hill). Transcription is the process in which DNA is converted to RNA. Ribonucleic Acid (RNA) is a polymeric molecule. RNA is involved in protein synthesis, and it is sometimes even in the transmission of genetic information. The main job of RNA is to transfer genetic information that is needed for the creation of proteins from the nucleus to the ribosome. Without RNA proteins could never be made (News-Medical). Transcription is the process of making an RNA copy of gene sequences. This particular copy leaves the cell nucleus and enters the cytoplasm. Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to amino acids during protein synthesis. In the cell cytoplasm the ribosome reads the sequence of the mRNA in groups made up of three bases to assemble the protein (NIH). DNA, RNA, Transcription, and Translation are all mandatory for human growth and development. DNA is what makes each and every person unique and different in this world. DNA also helps us better understand why and even how things work. Every cell in our

    Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule.…

    And consequently, to understand gene expression is to understand why these mutations can have such grave effects on an individual. For DNA to direct cellular processes, it must be transcribed and translated, The AP Biology Curriculum Framework explains. It goes on to say that “the products of transcription and translation play an important role in determining metabolism, i.e. cellular activities and phenotypes.” So if “changes in a nucleotide sequence, if present in a protein-coding region, can change the amino acid sequence of the polypeptide” (AP Biology Curriculum Framework, p. 37), changes to these essential proteins prevents cellular activities from being performed. The field of gene therapy began due to knowing about mutations and their effects on gene expression.…

    The Basics of Gene Expression and Control Genetics is a very diverse field of science, because it encompasses so many aspects of not only what happens inside organisms, but also how offspring relate to parents and ancestors and many other processes. Although every bit of genetics is important, many things in an organism would not be possible without the expression of genes. Through expressions of genes, organisms provide for themselves and "fulfill" what is the basis of their genetic possibility. These processes of transcriptional gene control, translational gene control, and post-translational gene control helps make key components that help an organism function in many ways.…

    DNA gives cells the potential for specific behavior, but this potential will only be realized if the gene is expressed. A gene is expressed if the DNA is transcribed into RNA and then converted into a protein. These proteins can have many different effects on the cell, such as metabolism or neurotransmission. We are now able to tell which specific genes are expressed at a particular time. Gene expression is uncommon, however, with no transcription and only the potential for a behavior as a result.…

    The proteins and enzymes involved in the DNA replication process are: 1. DNA polymerase – it is the enzyme that synthesizes DNA and adds nucleotides to the 3’ end of the growing strand (Pierce, 2013, p. 241). 2. Telomerase – an enzyme, which has both a protein and an RNA component, extends the telomeres by making copies of the repeat sequence (Pierce, 2013).…

    As the largest organelle, and the first to be discovered [1], the nucleus is the control center of the cell. Given its name by Scottish Botanist, Robert Brown, the nucleus is responsible for all cellular processes in eukaryotic cells and usually fills approximately 10% of the cell's volume [1]. The reason for this organelle's large size is because of the DNA it contains. In fact, each human contains approximately six feet of DNA which is tightly packed and highly organized by proteins, the majority of it stored in the nucleus [1]. With this DNA, the nucleus produces needed proteins which are then used for cell growth, reproduction, and the overall functioning of the cell [2].…

    Describe the chemical structure and function of DNA DNA is a fundamental molecule responsible for the growth and maintenance of the human body. Since the discovery of DNA and its double helix structure though the Watson-Crick Model, there has been a significant increase in the understanding of human disease and development of effective treatment. DNA’s specific chemical structure allows it to carry out its function which therefore maintains our survival. Deoxyribonucleic acid is a macromolecule consisting of double stranded polynucleotide chains joined together by hydrogen bonds between complimentary bases, forming the double helix. Each strand is made up of many nucleotides joined together in a complimentary fashion by phosphodiester bonds,…

    Replication, first, came about because RNA was formed. This occurred because organic molecules on Earth were able to form ribonucleotides from the assistance of a clay catalyst. Eventually, these ribonucleotides formed RNA, which, through time, began to fold and replicate itself. As replication got faster, RNA's started to attract amino acids and hold them together. Bonds started forming, and proteins were able to be produced.…

    My protein synthesis analogy is a softball team. My analogy is about the softball team playing defense (in the field) not offense (up to bat). The nucleus is the dugout because the coach is in it and the players exit and enter it. The DNA is the coach because he makes all the plays and decides the lineup, or everyone’s position in the field. The mRNA is the catcher, who receives the signal from the coach and sends it to the pitcher and the other fielders.…

    Possible Modifications of Central Dogma of molecular Biology Introduction The central dogma of molecular biology is describes the transfer of genetic information within a biological system and was first stated by Francis Crick in 1956. The central dogma is the flow of genetic information as ‘’DNA makes the RNA and RNA makes the protein. ’’All biological cells with few exceptions in some follow this rule. This flow takes place through three fundamental processes: replication, transcription and translation.…
