What is needed for dna to be copy

Biology

Answer:

DNA needs RNA to be copied.

Explanation:

The transcription process starts by DNA "Unziping" itself and the RNA polymerase matches up to its allele. This then copies the DNA and it is sent out to a ribosome for the translation process.

Answer:

DNA carries the information for making all of the cell's proteins. These pro­teins implement all of the functions of a living organism and determine the organism'­s characteristics. When the cell reproduces, it has to pass all of this information on to the daughter cells.

Before a cell can reproduce, it must first replicate, or make a copy of, its DNA. Where DNA replication occurs depends upon whether the cells is a prokaryote or a eukaryote (see the RNA sidebar on the previous page for more about the types of cells). DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same.

The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions. The beauty of this structure is that it can unzip down the middle and each side can serve as a pattern or template for the other side (called semi-conservative replication). However, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule.

Let's look at the details:

   An enzyme called DNA gyrase makes a nick in the double helix and each side separates

   An enzyme called helicase unwinds the double-stranded DNA

   Several small proteins called single strand binding proteins (SSB) temporarily bind to each side and keep them separated

   An enzyme complex called DNA polymerase "walks" down the DNA strands and adds new nucleotides to each strand. The nucleotides pair with the complementary nucleotides on the existing stand (A with T, G with C).

   A subunit of the DNA polymerase proofreads the new DNA

   An enzyme called DNA ligase seals up the fragments into one long continuous strand

   The new copies automatically wind up again

Different types of cells replicated their DNA at different rates. Some cells constantly divide, like those in your hair and fingernails and bone marrow cells. Other cells go through several rounds of cell division and stop (including specialized cells, like those in your brain, muscle and heart). Finally, some cells stop dividing, but can be induced to divide to repair injury (such as skin cells and liver cells). In cells that do not constantly divide, the cues for DNA replication/cell division come in the form of chemicals. These chemicals can come from other parts of the body (hormones) or from the environment.

tamaranim1 [39]
This was a major breakthrough in geology because it meant that sedimentary strata in diverse parts of a country or area could be correlated as belonging to the same formation which means they were formed at the same time historically so helped to put them in the correct sequence. If these strata contained valuable minerals like coal then it could aid in the search for coal. This helped William 'Strata' Smith in England to create his first geological map in the world of a whole country.
