TheGarbageMan: When she turns to ash?
Jan Macek: Nigerian men understand respect. Although that's starting to degrade in recent years. But they respect their parents and family and their women. If you want to start a fight then just insult any of them. I still remember the first time I heard my dad swear and almost punch someone cuz he bumped into my mom and tried to blame her.

Nakic Avdic: Just i though Florida was filled with asshole Cali got it bad.
Idolfun14: SO MUCH BULLSHIT :''DDD
Asco Corp.: I guess black people don't have a language or accent.
How Bacteria Work
Bacteria do not REPRODUCE sexually, they reproduce asexually by splitting ( referred to as binary fission). The outcome of asexual reproduce is essentially the same as cloning: you get a new individual and that individual is genetically the same as the "parent" (has the exact same genes). HOWEVER. Bacteria can reproduce both sexually and asexually. Go through this Buzzle article for a brief overview about the same. How do bacteria reproduce. Unlike other organism, bacteria have many methods of reproduction like. l. Asexual reproduction. a. Binary fission. b. Spore formation. 2. Sexual reproduction. a. Transformation. b. conjugation. c. Transduction. Asexual reproduction: This happens by simple cleavage of the cell. This is of two types.
- Bacteria can reproduce both sexually and asexually. Go through this Buzzle article for a brief overview about the same.
- Bacteria cannot reproduce sexually, but some types of bacteria exchange their genetic information in a process called genetic recombination. During this process, two bacteria The assembly of the viral genome and its capsid does not involve enzymes as is the case during cellular DNA replication. The process is usually.

- 29 Nov This is very different from reproduction in humans. Bacteria, being a prokaryotic, single-celled organism, must reproduce asexually. The advantage of asexual reproduction is that it can be very quick and does not require the meeting of a male and female organism. The disadvantage of asexual reproduction.

- The usual vegetative bacterial cells are haploid and in sexual reproduction part or all of the chromosome passes from the male cell to the female cell, yielding a cell, i.e., partly or completely diploid. Crossing The lighter viral particles and those particles which did not enter the bacterial cells were found in the supernatant.

3 Types of Sexual Reproduction that occurs in Bacteria (1869 Words)
Sexy reproduction is a dream up of reproduction where two morphologically distinct types of specialized reproductive cells shouted gametes fuse together, involving a female's large ovum or egg and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell margin , which only occurs in eukaryotic cells, known as meiosis.
The two gametes fuse during fertilization to produce DNA replication and the creation of a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination , genetic material DNA joins up so that homologous chromosome sequences are aligned with each other, and this is followed by exchange of genetic information. Two rounds of cell division then bring up four daughter cells with half the number of chromosomes from each true parent cell, and the same number of chromosomes as both parents, all the same self-fertilization can occur.
In the interest instance, in human clone each human cell contains 46 chromosomes, 23 pairs, except gamete cells, which only contain 23 chromosomes, so the child hand down have 23 chromosomes from each parent genetically recombined into 23 pairs. Chamber division initiates the occurrence of a new original organism in multicellular organisms ,  including animals and plants , for the purpose the vast majority of whom this is the primary method of imitation. The evolution of sensual reproduction is a notable puzzle because asexual propagation should be able to outcompete it as now and again young organism created can bear its own under age.
They reproduce very fast that, a colony of bacteria will double in just half and hour. They can reproduce in many ways yet maintain the genetic diversity and robustness. Unlike other organism, bacteria have many methods of reproduction like. This happens by simple cleavage of the cell. This is of two types viz. Here a single bacteria undergoes division to two new bacterial cells. This the most common process. This is the most common method of reproduction.
This occurs during favorable conditions. Here a single bacteria can split into two bacteria.
- How do Bacteria Reproduce
- Bacteria, like other forms of life on Earth, need to make copies of themselves to survive.
- This is not true sexual reproduction, but it does allow for the exchange of genetic material. A sexus pilus forms and attaches one bacterial cell to another. The genes for the bacteria form into something called a plasmid. The plasmid is then transferred from one bacterium to another. In this way bacteria can pass valuable . 24 May They do not reproduce by conjugation. Like you said that is simply swapping DNA material between the two. This process is referred to as the bacteria having sex though, but they reproduce via binary fission. chill45, May 24,
Bacteria prokaryotes means they are very quiet, single-celled organisms. The most of their reproduction is done asexually via binary fission. That means that they frankly double their genetic figures and group in half, much near cell part. The use to bacteria to propagate in that manner is that they can do so extraordinarily quickly.
Their reproduction clip in a favorable setting is exponential. They can grow so quickly in a petri dish that they some time must be transferred to a late-model home or they wishes die as a aftereffect of consuming all the food accessible to them. Some bacteria are non-poisonous while others can be pathogenic. Asexual reproduction as well gives bacteria an influence in numbers.
Cytologic observations and genetic studies indicate something like sexual reproduction, involving the fusion of two different cells and a transfer of hereditary factors occurs in bacteria although infrequently.
Genetic recombination occurs in those bacteria that have been carefully studied and presumably occurs in other species as well. One of the most intensively studied species of bacteria, Escherichia coli has been shown to have sex-some act as males and transfer genetic information by direct contact with females.
The usual vegetative bacterial cells are haploid and in sexual reproduction part or all of the chromosome passes from the male cell to the female cell, yielding a cell, i. Crossing over then occurs between the female chromosome and the male chromosome or fragment, followed by a process of segregation that yields haploid progeny cells. The genetic transfer in bacteria also occurs by transformation, in which the DNA molecule of the donor cell, when liberated by its disintegration, is taken up by another recipient cell and its offspring inherit some characters of the donor cell.
When different strains of bacteria are found in a mixed state either in culture or in nature, some of the resultant offspring possess a combination of characters of the parent strains. This phenomenon is known as recombination. The phenomenon of transformation was first recorded by Griffith Avery, Macleod and McCarty demonstrated that the transforming principle being DNA in the sequence of events in bacterial transformation.
The lines of inquiry that led to an understanding of the chemical nature of genetic material arose from a study of the pestilent organism Diplococcus pneumoniae. This bacterium causes pneumonia in males. In , Frederick Griffith found that there are two strains of D.
