a.cell fusion -2 Living cells fused using synthetic medium artificially, it casues karyoplast fusion as well as cytoplast fusion, When an undifferentiated stem cell fuses with a mature differentiated cell, the resultant cell can retain the mature cell \n\nb.Tissue culture - A branch of biotechnology working using invtro cell lines in a petridish growing in 37 degree incubator with 5% Carbon dioxide.. example Hela cell lines - A cell line obtained from Henrita laks ( other exapmles like  tissues cut from kidney or other tissues and homogeneous suspension is  made  and grown in dishes to study drug targetting and for transfection.Also in plants small part of bud is cultured in a test tube with appropriate shoot inducing and rooinducing hormones to get plants with desired charecters .A biotechnology teaching college is incomplete without a tissue culture lab aslo known as cell culture lab\n\nc.Recombinent DNA - Most of the times bacterial plasmids are engineered to ligate with gene of interest using enzymes to obtain required protein ,usually used for commercial purpose and also for research purpose ( recombining DNA -a major feild also called as genetic engineering )\n\nd.Embryo transfer - 2 kinds of embryo transfers are commenly seen .One in the laboratory,it is done using mouse embryos, after embryo manipulations , to obtain transgenic animals or knock out animals or for other purposes embryos are transfered to a surrogate mother ,It is done in two ways. uterine or oviduct (depending on the stage of the embryo) , 2nd one ,in hosipitals  invitro clininc IVF therapy ,Embryos are transferred using a cappilary pipe and a syringe,through the vegina ( generally in blastocyst stage)to the mother after invitro fertilisation for those mothes who has problem in natural fertilsation and also for various other reasons ,to get disigned babies .Embryo transfers are also practicved in other animals as well .Dolly is also a gud example born after embryo transfer after somatic cell nuclear transfer \n\ne.Artificial insemination - Here sperm is placed into a female's uterus by artificial means unlike natural copulation.Semen is collected, extended, then cooled or frozen. It can be used on site or shipped to the female's location.artificial insemination were first developed for the dairy cattle industry to allow many cows to be impregnated with the sperm of a bull with traits for improved milk production.and also in other animals .In humans artificial insemination is usually part of an infertility treatment; either the woman's partner's sperm (artificial insemination by husband, AIH) or donor sperm (artificial insemination by donor, AID) can be used.\n\nf.protoplast fusion - a technique used to generate genetically modified fruits,Protoplast is nothing but cell minus cell wall , so two protoplasts are fused from two fruits after removing cell wall using generally PEG and sendiviruses to enhance fusion .Generally it causes somatic cell fusion.Protoplasts are useful in genetic manipulations because they do not have cell walls. They are ideal targets for taking up naked DNA and for fusing with protoplasts of other related species. In the related genus, Episcia, some species and selections have true yellow and red flowers. this procedure has been successfully applied  for plant regeneration from African violet protoplasts to protoplasts of Episcia cupreata Tropical Topaz .Several researchers have emphasized production of hybrids between distantly related, sexually incompatible species, not all are success stories there are more failure also .\n\ng. test tube baby - A test-tube baby is the term that refers to a \nchild that is conceived outside the woman's body.  The first \nsuccessful test-tube baby was born in England in 1978 and since then.over 20,000 test-tube babies have been born worldwide. The process is referred to as in vitro (outside the body) fertilization.Simply put, eggs are removed from the mother's ovary and inc

Almost all cells reproduce like amoeba. There are very, very few that do not.\n\nSo take your pick. Turkey stomach cells reproduce like amoeba, pine needle cells reproduce like amoeba, human lung cells reproduce like amoeba.

Absolutely, I suggest\n\nYang X, Tian XC, (2002). Cloning adult animals - what is the genetic age of the clones? Cloning, 2(3):123-8. \n\nThat is an almost perfect review!\n\n:-) Happy reading!

I believe the ecoli replicates much much faster than cultured human pancreatic cells.

Check out "mitosis" in a suitable source (Wikipedia, for example).  The process is a bit long to describe here.

Well, in human cells it's about 3 hours.  There are 3 billion base pairs in the human genome, so that's around 1 billion bp/hour (depending on temperature) for complex prokaryotic cells.

Replication of DNA occurs in the "S" phase (or Synthesis phase) of the cell cycle process. Usually, people perform cell cycle analysis on cells fixed at progressively differing time points. In our laboratory, we fix our cells with 70% EtOH at 0, 12, 18, 24, and 48 hours. Then we use a FACS calibur machine to visualize and quantify the percentage of cells in each phase of the cell cycle.

Cancer speeds up the process.  Spells divide more rapidly, and the cells that are produced are a little weaker then normal cells and they clump together and form a tumor.  Which then keeps growing, but it is still the body producing cells, so white blood cells don't see it as malignant.  \n\nCarcinogens cause the cells to divide rapidly.

This is dependent on the type of organism, the stage in the lifecycle of the organism, and a wide variety of environmental factors such as temperature, availability of nutrients, presence of toxic compounds, and organism-specific biological signalling compounds which play a role in regulating gene expression.\n\nTo take a simple organism such as a bacterium, it is a reasonable assertion that levels of gene expression are highest under conditions that are optimal for reproduction (optimal temperature and moisture conditions, high availability of nutrients, low concentrations of toxic compounds).  This is because during asexual reproduction, proteins are required both as building materials for replication (e.g. cell wall constituents, structural proteins, enzymes required for metabolism etc.) and for the actual process of replication (proteins involved in DNA replication and protein synthesis etc.).\n\nOf course, without knowing the specific organism you are referring to it is not possible to answer your question except in broad terms.  You might try looking at a text book such "Biological Science" by R.Soper (Cambridge University Press).

mitosis is asexual reproduction, cells divide and reproduce replicating their own DNA exactly\n\nmeiosis is sexual reproduction, new cells contain only half of their original DNA, and half from a different parent source

gametes in humans are produced through meiosis. This process produces four daughter cells, each with only half of the DNA of any other cell. Normal, or autosomal cells, have 46 chromosomes, 2 pairs of each type. Sex cells, gametes, have only one of each type chromosomes, 23 total.

Fertilization of an egg with sperm can occur in vitro (in a test tube). Under proper conditions, a blastocyst will form after about 5 days. The blastocyst contains a group of cells called the inner cell mass. These cells are pluripotent, meaning they can differentiate into any cell in the human body. These are commonly referred to as "embryotic stem cells".

Cloning currently requires a donor stem cell.  The easiest place to get a stem cell is in a blastocyst, which is essentially the beginning of an embryo.  To play devil's advocate, in order to get a stem cell, there has to be a dead "baby".  The easiest way to get a dead "baby" is to artificially inseminate an egg and incubate it.  Religious people tend to argue that that little blastocyst was a human being, while to scientists it is nothing more than a conglomeration of cells with the potential to be a human.  \n\nThat is the source of the true controversy of cloning.  Any other issues are merely sidelines or billboards for ignorance.
