Nucleus accumbens

contains forty-six chromosomes and forty-six centromeres but now they have only forty-sixchromitids.You may ask where this happens, and this can only happen in eukaryotic cells because they have a membrane-bound nucleus to make a copy and in prokaryotic don't have a membrane-bound nucleus so they can't go through mitosis. This is important because when people have a cut on their skin, mitosis allows the body to heal itself by creating new cells to go in place of the cell. When a person grows taller

. Bacteria and Archaea are split into separate domains because bacteria include all pathogenic prokaryotes, as well as nonpathogenic prokaryotes that are found in soil and H2O. What are also found in this domain are photoautotrophic prokaryotes. Archaea includes prokaryotes that do not have peptidoglycan in their cell walls. Prokaryotes are mostly related to eukaryotes than they are to different prokaryotes. This is when they were split into two domains. 2. Similar genetic sequence can

a. Firstly, the cytoskeleton is one of the many membrane bound organelles which is only found in eukaryotic cells and not prokaryotic counterparts. The cytoskeleton is a series of proteins within the cell which provides the cell with shape and support. The cytoskeleton also mediates some aspects of movement by helping the cell move in its environment and by controlling the movement of other cell components. A second organelle which eukaryotes possess and prokaryotes do not possess includes the

Compartmentalization provides advantages in Eukaryotic cells because it provides the optimal environment for different metabolic functions. So many metabolic functions can happen inside one cell. 2. Explain how the nucleus controls protein synthesis in the cytoplasm. The nucleus creates mRNA and the mRNA goes through the nuclear pores into the cytoplasm. The mRNA is transcribed the from the DNA. Once the mRNA enters the cytoplasm it is translated by ribosomes, than the corresponding amino acids

Prokaryotic and eukaryotic cells are different in regards to structure and size. Prokaryotic cells are not as complex as eukaryotic cells. To begin with, prokaryotic cells do not have a nucleus. The DNA is enclosed in the capsule of the prokaryotic cell. In contrast, the eukaryotic cell has a nucleus which contains the DNA. The eukaryotic cell is much larger than the prokaryotic cell. The eukaryotic cell is roughly a thousand times the size of a prokaryotic cell (Singh-Cundy, A., & Shin

the sequences in which the bases in DNA carry the instructions to make the correct protein RNA now forms new base pairs with one strand of DNA it is then and only then that it has converted from RNA to mRNA which is messenger RNA which leaves the nucleus and enters the cytoplasm. The cytoplasm of the cell also contains tRNA in other words Transfer RNA which carries an amino acid the amino acid comes from the protein that you intake in your own diet. tRNA and mRNA combine via the codons which are located

PRECAUTIONS General safety instructions followed during lab experiments comprising wearing lab coats, safety glasses, and disposable gloves. Also, no open toe shoes allowed in the lab. Generally, pipetting skills are important through all experiment especially for Bradford assays because the absorbance reading very sensitive to bubbles and so the concentration of the samples. Whereas in SDS-PAGE experiment, preparation and fast demonstration is very important to avoid solidifying the gel before transfer

Citrate is known to prevent the agglutination of red blood cells while ConA on the other hand based on our experiment from Lab 7 we saw it was functional and was able to bind to our red blood cells. If ConA is able to agglutinate the cells that means it is biologically active. In our experiment we plated another variable by adding red blood cells and ConA and sugars to see whether the sugars interfered with ConA’s ability to bind we noticed that galactose did not interfere with the agglutination

analogy about how the cell organelles are just like the imaginary movie land called “Whoville”. In the cell the one organelle that keeps everything in order in the cell is the Nucleus. For the analogy of the Nucleus I will be using the mayor of Whoville. The mayor keeps order and everyone will follow what he says, just like the Nucleus. Another organelle that has an analogy is the “Mitochondria”. The Mitochondria is what makes or produces energy for the cell. For this I will be using the people that made

Prelab Questions Analyze prokaryotic and eukaryotic cells. 1.Similarities : They both have DNA as their hereditary material.They are both layer bound.They both have ribosomes. They have comparative fundamental digestion system. They are both amazingly various in structures. Diferences: Eukaryotes have a core, while prokaryotes don't. .Eukaryotes have layer bound organelles, while prokaryotes don't. The organelles of eukaryotes permit them to show much more elevated amounts of intracellular division
