FISH CLONING AND SPAWNING MADE EASY

INTRODUCTION

Cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as fish, bacteria, and insects, and other animals including humans or plants reproduce asexually.

Cloning in Biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. Molecular cloning refers to the process of making multiple molecules, cloning is commonly used to amplify DNA fragments containing whole genes, but it can also be used to amplify any DNA sequence such as promoters, non-coding sequence and randomly fragmented DNA. It is used in a wide array of biological experiments and practical applications ranging from genetic fingerprint to large scale protein production.

Cloning of any DNA fragment essentially involves four steps;

Fragmentation:  Breaking apart a strand of DNA.

Ligation: Gluing together pieces of DNA in a desired sequence.

Transfect ion: Inserting the newly formed pieces of DNA into cells.

Screening/ Selection: Selecting out the cells that were successfully transfected with the new DNA.

MATERIALS FOR FISH CLONING

METHOD OF FISH CLONING

Using Zebra fish as example;

Zebra fish served as an excellent model for understanding normal development and birth defects. More recently, research with Zebra fish has extended to model human diseases and to analyze the formation and functions of cell populations with organs.

 The normal cloning technique uses an unfertilized egg and a donor cell. The DNA is removed from the egg and replaced from the donor. The egg is then coaxed into dividing the resulting fish is an exact genetic copy of the donor.

Using Gibelli and colleges technique, the egg is gently removed from the female Zebra fish and placed in a solution of ovarian fluyid from a chinnok salmon. This worked well, because it kept the egg inactive for sometime in about two or three hours. Zebra fish was useful in the exercise because their eggs are transparent and the fish development is easy to follow.
Though reproductive cloning generally uses somatic cell nuclear transfer (SCNT) to create organisms that are generally identical. This process entails the transfer of a nucleus from a donor adult cell (somatic cell) to an egg from which the nucleus has been removed, or to a cell from a blast cyst. If the egg begins to divide normally, it is transferred into the uterus of the surrogate mother. Additionally the mitochondria in the cytoplasm also contains DNA and during SCNT, this mitochondrial DNA is wholly from the cytoplasm donor’s egg, thus the mitochondrial genome is not the same as that of the nucleus donor cell from which it was produced.  This may have important implications split for cross species nuclear transfer in which nuclear mitochondrial incompatibilities may lead to death. Artificial embryo splitting or embryo twinning, a technique that creates monozygotic twins from a single embryo is not considered in the same fashion as other methods of cloning. During the procedure, a donor embryo is split in two distinct embryos that can then be transferred via embryo transfer. It is optimally performed at the 6 to 8 cell stage, where it can be used as an expansion of IVF to increase the number of available embryos. If both embryos are successful, it gives rise to monozygotic (identical) twins.

ADVANTAGES AND DISADVANTAGES OF FISH CLONING

Advantages:

Ø The exercise produces new offspring that are genetically identical, they will all have the desired characteristics.

Ø  Organisms that are difficult or slow to breed normally can be reproduced quickly.

Disadvantages:

Ø If a clone is susceptible to disease or changes in the environment, then all the clones will be susceptible.

Ø It will lead to less variation, and less opportunity to create new varieties in future.

SIGNIFICANCE OF FISH CLONING IN BIOLOGY AND BIOTECHNOLOGY

·        Molecular cloning allows scientists to not only discover what proteins are present and their function, but also explore what happens in a cell wall when these proteins are changed. When studying cell divisions, specifically, scientists look for proteins that control the beginning and end of division, even the replication within the cell, example; Histones.

·        By manipulating cells with cloning and learning more about specific proteins, scientists can take their research and apply it to large- sale research endeavors like diseases and pathogens.

·        It is vital to note, however, the cloning is not used to study just proteins involved in the cell cycle. Molecular cloning has lead scientists to discover the entire genetic sequences of many different species, inactivate genes in both human and other organisms and create transgenic like herbicide resistant plants and glow- in- the dark fish. For instance, when tropical fish give off a slight glow because they have been marked with the same fluorescence that is native to some species of jellyfish.

·        The biotechnology significance; the cloning of zebra fish by nuclear transfer from long- term cultured cells opens a new avenue for gene targeting in this important model organism.

I can help you develop a unique business plan tailored to suit your needs.

I will carry out research and develop MBA grade business plan that you can present to a bank or any investor.

Chris Farm Nigeria develops well self-explanatory, irresistible feasibility studies or business plan for your Business start ups, Business Growth or Expansions through either personal funds, Grants, or loans, which could be new or existing ones. We delight in writing for people under Academic sectors, production sectors, manufacturing sectors, processing or packing sectors, advertising sectors, marketing sectors and other related sectors on mini, middle and large scale businesses.

For your Agribusiness, either production, processing, marketing of any Agro-industry, our feasibility studies or business plan are explicit.

Generally, our feasibility study and business plans are developed so well that it becomes irresistible when you show them to your investors or sponsors. It gives you a clear picture of what you are expected to see when you put the feasibility study or business plans into use. It also shows how much it will cost you to own your desired business, what your money can afford. The kinds of product you will need to minimize input in other to maximize output, and how much returns you will get at the end of each accounting year until your business break-even on its initial investment capital. This will give the intending business person or investor or farmer, a vivid idea on the possible benefit he or she stands to gain, when he or she starts doing the business. With that, the intending business person or investor or farmer will not need a soothsayer to make decision for him or her.

·         This is just a sample of our executive summary on poultry feasibility study and business plan, carried out in Rivers State. 

·         1st sample;


These Feasibility study on poultry farming business (specializing on layers and boilers production), was conducted using projections, impressive publications, compounding interest/values, tables, graph, bar chart, pie chart, profits analysis and cash flow positions in other to give a clear picture of what is obtainable in that location, using eight plots of land, at Esemdiary village, Off Effurun Sapele Road, Okpe LGA of Delta state, Nigeria as a case study. 

Esemdiary village is a community in Okpe Local Government Area of Delta State with coordinates 05°26’N 5°57’E, which also plays the host community to the Warri Airport, which is actually located at Osubi. 

Okpe Local Government is a territory that used to be part of the original Okpe Kingdom, its headquarters is at Orerokpe, with a population of 128,398 people whose primary occupations include commercial farming, fishing, hunting, trading and gas exploration. 

After carrying out the feasibility study on Esemdiary village, Off Effurun-Sapele Road, Okpe LGA of Delta state, Nigeria, it was discovered that, farming generally will do well both on crop and animal production.
