Evaluation: The graph that was produced shows that Whitefish Blastula cells spend the most amount of time in interphase followed by prophase, metaphase, anaphase and finally telophase. Relative time was found by finding the total number of cells in each phase and then dividing it by the total number of all cells counted and finally multiplying by 100. Doing this showed that the cell that takes up the most amount of time is interphase at 71.35%. Although I was unable to confirm the accuracy of…

Stage 1 Biology Practical Report Isabelle Bury C2 Surface Area : Volume ratio Introduction: A cell is described as the basic unit of all living things and is commonly known as a building block for these living organisms. Cells are considered the fundamental unit of life as it relates to the metabolic processes occurring which allow organisms to stay alive. Cells are responsible for providing structure within organisms, absorbing nutrients from food sources and converting nutrients into energy.…

Discuss the similarities and differences in DNA replication between eukaryotes and prokaryotes. Are the changes in eukaryotes adaptations? Explain. Introduction Before we start our discussion, let us refresh our memories; cells are the absolute smallest building blocks of life, each manifesting a sophisticated design. Broadly speaking, the cells are divided in eukaryotes that contain membrane-bound organelles; and prokaryotes that do not (Diffen, 2007)—in short, prokaryotes are both simpler and…

This theory can be further expanded as specific eukaryote cells underwent secondary symbiosis, a process by which the larger host cell engulfs a eukaryote that has previously undergone primary endosymbiosis (McFadden,2001). It is speculated that this phenomenon occurred widely among species,ultimately resulting in the product of many unique and complex organisms present today (McFadden, 2001). Therefore the development and evolution of many species can be attributed to the endosymbiosis between…

which also refers to the synthesis of RNA copy of information encoded on DNA. The same principles of transcriptional regulation apply to both eukaryotes and prokaryotes. Transcription involves in access of transcription apparatus to DNA, recognition of promoter sequences, initiation of RNA synthesis, elongation of RNA, and termination. Transcriptional in eukaryotes is more complex compared to prokaryotes especially multicellular organisms In DNA transcription, the short segments of chromosomes…

A Comparison of Protein Synthesis between Eukaryotes and Prokaryotes The different fundamental organisation of genetic material and organelles between eukaryotes and prokaryotes leads to dissimilar processes of protein synthesis. The larger eukaryotes have a more intricate pathway associated with protein synthesis, due to both the biochemical structure of organelles and enzymes, and also the transport of genetic material within cell. In this essay I hope to explore the differences of gene…

are similar yet very different. But in addition to the eukaryotic and prokaryotic cells, we have viruses—they are not regarded as life in the scientific community, however, they are important because they infect those which have life (i.e humans). Eukaryotes, prokaryotes and viruses are entities that we come in contact with everyday and therefore need to be studied. There are three prominent ways in which biologists can compare and contrast them: their size and external structures, the…

molecule between the codon, the three nucleic acids and the amino acid after which a specific protein will be synthesized. It is the intermediate in Protein Synthesis which interprets the genetic code. Without tRNA, translation in prokaryotes or eukaryotes could not take place. Common Features of tRNA Molecule Each amino acid has at least one tRNA molecule. Therefore, these tRNA molecules have a common design as they have to all have the ability to interact with the ribosomes, mRNAs and…

Eukaryotes typically do not use rolling circle replication, its typically used by bacteriophages and viroids. Rolling circle occurs when a circle chromosome replicates only one strand of DNA (as mentioned above its usually the lagging strand). Some eukaryotes can have rolling circle transposons but in general Eukaryotes have linear DNA and do not typically need to use Rolling circle replication compared to prokaryotes…

favorable conditions (reviewed in KOONIN 2000). Thus, it will further our understanding of the basics of cell functioning. From a practical perspective, some essential genes that are conserved across all or most of the pathogenic bacteria but not in eukaryotes could become attractive candidates for broad-spectrum drug targets (reviewed in GALPERIN AND KOONIN 1999). In human, it has been demonstrated that mutations in essential genes contribute to a spectrum of human diseases, from developmental…
