Download file to see previous pages Eukaryotes vary from single cell amoeba to multi-cellular creature like human-being and dinosaur, which is now extinct.
The eukaryote cells are characterized by a nucleus which contains chromosomes and DNA that carry hereditary genes. The cells have various other subparts like organelles like mitochondria, golgi bodies, flagellum etc. There are different types of eukaryote cells. The plants and animal eukaryote cells primarily differ in the cell membrane and presence of plastids. The plant cells have well defined cell membrane, plastids, chlorophyll, and cytoplasm which have specified functions. The animal cells, on the other hand, do not have well defined cell membrane and do not contain plastids and chlorophylls. They have smaller vacuoles. Some eukaryote cells like phagocytic cells engulf other harmful structures and anti-bodies and create more complex structures.
Few of the common features of eukaryote cells is the multi-cellularity and tissue formation (Eukaryotes). The extrusive organelles are defense mechanism for plants and animals. Cell divisions are part of development cycle and primarily constitute of mitosis and meiosis or cytoplasm division.
Eukaryote cells are vital centre of information mainly because of the presence of chromosomes in nucleus that has DNA. The DNA are carrier of hereditary genes and become extremely important link to trace the morphological evolution of living species. During the cell division, the division of nucleus into two identical parts helps to carry forward the genetic characters of the parents to the off-springs. The study of eukaryote cells in the fossils give crucial information regarding the type of organisms that existed millions of years ago and promote better understanding of evolution process of living organisms through the ages.
Eukaryotes are also essential for carrying out various routine but complex body functions. The various sub compartments and sub organs of the cell like vesicles, vacuoles, ...Download file to see next pagesRead More

...? Molecular and cellular Biology Essay Questions 12/04 Question 2 Genetic Engineering: Genetic engineering is one of the most advanced technologies that is being used these days. It is a laborious process and requires extensive research. Genetic engineering is a process in which gene is taken from one organism and incorporated into other. Genes may be incorporated into bacteria, plants or animals. In this process recombinant DNA (rDNA) technology is used to incorporate gene of interest into organisms and that organism in which gene is inserted is said to be genetically engineered. Through this process off springs with unique characters are produced. Recombinant DNA is also referred to as Chimera. By the...

Biochemistry and Molecular Biology

...Biochemistry and Molecular Biology Introduction: The concepts of biochemistry and molecular biology are slightly different yet related to each other. While molecular biology is determined on an understanding of the molecular activities within a living organism, the study of biochemistry focuses on the findings obtained as a result of the molecular biology thus enhancing the knowledge on the different molecular and cellular processes within the living organism (Wilson & Walker, 2010, p.1). The present study has taken into consideration certain molecular...

GENETIC & Molecular BIOLOGY

...Genetics and Molecular Biology Question 2) When looking at two different species, specifically the horse which possesses 64 diploid chromosomes and 36 acrocentric autosomes, and the ass which possesses 62 chromosomes and 22 acrocentric autosomes, it is significant to investigate the genotype of the offspring. If one were to mate a male ass with a female horse, the offspring would be a mule with 63 diploid chromosomes. The reason that the mule (progeny of the ass and horse) has 63 diploid chromosomes is as follows: The male ass has 62 diploid chromosomes and therefore its gametes would contain 31 chromosomes each, after meiosis. The female horse has 64 diploid chromosomes and 32 chromosomes in her...

...Cyclin gene TTherm_00425970 expression during conjugation of the ciliate Tetrahymena thermophila The goal of this study was to assess the role of individual cyclin genes of the eukaryotic microorganism, Tetrahymena thermophila, in the process of conguation, a sexual cell division cycle unique to the ciliated protozoans that involves a complex series of events that include meiotic and mitotic nuclear divisions, nuclear fusions, DNA elimination and amplifications and nuclear destruction. Gene expression patterns of the cyclin genes of Tetrahymena are known to both drive and respond to cell cycle events similar to these in other model systems. Microarray expression data for the cyclin genes of Tetrhymena thermophila were collected... in an...

...Biology 09 October Integration of Fossil and Molecular Data Integrating fossil and molecular data is just like opening a door to endless amazing discoveries on how the body of living creatures was formed. It has been established that molecular data along with morphological data played important roles in giving vivid details on the history of evolution. While it is true that molecular data or DNA data results to documented sequence of various events in the evolutionary development of specific specie, it cannot achieve any success in deciphering the evolution of species that lived hundreds or millions of years ago through fossils. It is in this regard that...

...Molecular Biology Monoclonal antibodies are used in research, diagnostics and therapeutics. Monoclonal antibodies are issued from one single cloneof cells. Monoclonal antibodies from mouse origin are easy to produce but their therapeutic availability is restricted by their antigenicity. Human monoclonal antibodies are produced by humanising mouse monoclonal antibodies. Monoclonal antibodies can be obtained by intraperitoneal injection into mice and collection of ascetic fluid produced. Since it is difficult to to remove antigenicity from the mouse, in vitro immunisation (IVI) protocol of human peripheral blood mononuclear (PBMC) cells for generating human antigen specific antibodies was developed. For monoclonal antibody, mice... is...
