Ribosome

How are proteins made? Where is the birth of proteins take place? It all starts with DNA. DNA is genetic information found in the nucleus of a cell. The first stage in order to make DNA is sending a RNA call mRNA (also known as messenger RNA). This RNA is can fit through pores from the cell’s walls, but DNA can’t because it is too big to fit in the pores, but RNA is small enough to fit through the pores. In the DNA strand there are nitrogen bases and three nitrogen bases in that strand are called

Polypeptides are chains of amino acids, which are all proteins. Proteins are made and developed outside the nucleus; in the ribosome. The way strung amino acids are put together is very important. The individual 3D and sequence must be correct, or else you will have a completely different protein. There are two different types of RNA which are involved in the entire process. They are transfer RNA (tRNA) and messenger RNA (mRNA). The mRNA, in the process of making new proteins, makes a copy of a gene

list of nitrogenous bases in the mRNA at the cell's ribosomes. I want to tell you what a codon is and tell you my five other journeys. A codon is where each three nitrogenous bases in an mRNA that helps a specific amino acid added to me the protein butterfly. My adventure begins when a ribosome comes together to an mRNA in the cell's cytoplasm. Then on my journey my BFF codon goes throught the ribosome, tRNA shares with the amino acid to the ribosome. My other friend anticolon does a great job of putting

genetic material in the form of DNA and controls many of the cell’s activities. The job of the nucleus is to protect the DNA and the RNA from anything outside the nucleus. Another organelle is the ribosome. Ribosomes are small particle of RNA and protein found throughout the cytoplasm in all cells. The ribosome is responsible for making protein by following the coded information from the DNA. The endoplasmic reticulum is where lipid components of the cell membrane are assembled, along with proteins and

which is the most important parts that makes or has intervention in every function in the cell, or mitochondria which gives the energy for the cell, besides the cell Membrane that is the controller center, and the chromosomes which are the DNA or Ribosomes which are the RNA (Reece et al 2009 & Nunn et al 2002). More importantly, Urry (2009) thinks that the cells differ from body to another depending on which organism it is. As an illustration, cells have two different kinds, also each kind has some

and out. The nucleus contains linear DNA in chromatin which protects the DNA from damage. Chromatin is formed of DNA which controls the activities of the cell. The nucleus often contains a structure called the nucleolus. This structure produces ribosomes which enter the cytoplasm in the cell through the nuclear pores, as well as transcribing DNA into RNA. Prokaryotic cells do not contain nuclei. Instead of having a nucleus to carry the DNA, these cells contain plasmids with circular DNA, as well

four parts, initiation, elongation, translocation and termination. Initiation attaches the mRNA to the ribosome and begins translation. Elongation is when new codons are exposed and new amino acids are added to the polypeptide. Translocation is the movement of mRNA through the ribosome and termination is when the stop codon is reached and the protein, ribosome and mRNA detach from each other. Ribosomes are key to this process. They have a large and small subunit that come together around the mRNA and

and what contributes to the process of replication. After creating DNA's helix structure, Watson moved on to investigating RNA's structure; it was then he discovers all RNA was to exist either as a viral component or to be combined with protein in ribosomes, which lead to his curiosity in protein synthesis in the ribosomal location.

membrane bound structure is the nucleus. Animals, plants, fungi, and protists are eukaryotic. Prokaryotic organisms are typically between 0.1 to 5.0 um in size while Eukaryotic organisms are between 5-10 um. Prokaryotic organisms have pili, cytosol, ribosomes, capsule, cell wall, plasma membrane, DNA, and chromosome also known as plasmids. (Cundy, 2012) They do not have a nucleus, lysosomes, microtubules, endoplasmic reticulum,
