How much of the cell cycle is taken up by cell division?
Very little of the cell cycle is taken up by cell division. Most of the cell cycle consists of cell growth and chromosome replication so the original cell can split into multiple cells.
What is a major difference between DNA replication and transcription?
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication.
What occurs during a lytic cycle?
The lytic cycle is one of two methods of viral reproduction, the other being the lysogenic cycle. These cycles should not, however, be seen as separate, but rather as somewhat interchangeable. The lytic cycle is typically considered the main method of viral replication (reproduction), since it results in the destruction of the infected cell.The lytic cycle is often described in steps, sometimes three steps, sometimes five steps or six steps. But all describe the same process. See the related question below for more information about the steps of the lytic cycle.Penetration To infect a cell, a virus must first enter the cell through the plasma membrane and (if present) the cell wall. Viruses do so by either attaching to a receptor on the cell's surface or by simple mechanical force. The virus then releases its genetic material (either single- or double-stranded DNA or RNA) into the cell. In doing, the cell is infected and can also be targeted by the immune system.Biosynthesis The virus' nucleic acid uses the host cell's machinery to make large amounts of viral components. In the case of DNA viruses, the DNA transcribes itself into messenger RNA (mRNA) molecules that are then used to direct the cell's ribosomes. One of the first polypeptides to be translated is one that destroys the hosts' DNA. In retroviruses (which inject an RNA strand), a unique enzyme called reverse transcriptase transcribes the viral RNA into DNA, which is then transcribed again into mRNA.Maturation and lysis After many copies of viral components are made, they are assembled into complete viruses. The phage then directs production of an enzyme that breaks down the bacteria cell wall and allows fluid to enter. The cell eventually becomes filled with viruses (typically 100-200) and liquid, and bursts, or lyses; thus giving the lytic cycle its name. The new viruses are then free to infect other cells.Lytic cycle without lysis Some viruses escape the host cell without bursting the cell membrane, but rather bud off from it by taking a portion of the membrane with them. Because it otherwise is characteristic of the lytic cycle in other steps, it still belongs to this category. Hepatitis C viruses presumably use this method.
Is it true that Replication occurs simultaneously at many points on a DNA molecule?
Yes it is. The eukaryotic DNA polymerase works much slower than the prokaryotic DNA polymerase, working at around 50 bases per second. With as many as 80 million bases to replicate the job is achieved in about one hour by having many replication forks. The simple answer: It's quicker.
How much water enters the water cycle?
30%
What part of the lysogenic cycle is like the lytic cycle?
Oh, dude, the prophage stage of the lysogenic cycle is basically the lytic cycle's cool cousin. It's like, "Hey, I'm just chilling in the host cell's DNA until I feel like wrecking the place." So yeah, they're kind of similar, but not as intense, you know?
How much of the cell cycle is taken up by cell division?
Very little of the cell cycle is taken up by cell division. Most of the cell cycle consists of cell growth and chromosome replication so the original cell can split into multiple cells.
A particular cell has half as much DNA as some of the other cells in a mititically active tissue. the in cell in question is most likely in?
The cell is most likely in the G1 phase of the cell cycle. During G1 phase, the cell prepares for DNA replication in the S phase. Cells with half the amount of DNA compared to others have likely already undergone DNA replication and are in the early stages of the cell cycle.
What kind of weather is wind associated with?
How much info do you want? The easy (and very flippant) answer is 'bad'. The complicated answer would be to do with differences in atmospheric pressure (caused by the rotation of the earth, it's effect on the oceans, the associated absorption of water in the rainfall cycle)
What is a major difference between DNA replication and transcription?
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication.
How might a distributed database designed for a local area network differ from one designed for a wide area network?
Data transfer on LAN is much faster than on WAN.Thus replication and fragmentation will not increase throughput and speed-up on a LAN, as much as in a WAN. But even in a LAN, replication has its uses in increasing reliability and availability.
What is a major difference between DNA replication DNA transcription?
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication.
Which blank CD is best for CD replication?
The brand of blank CDs that are best for CD replication is debatable. While one brand is very much like another when it comes to CD replication quality, the cost of CDs is very important when choosing the one that's right for you.
How difficult is data replication?
Data replication is difficult without formal technological training and/or education. A lot of the terms used to describe data replication and the processes necessary to complete it are computer-specific and could appear to be in a completely different language to a person that does not know much about computers or technology.
