(c)++DNA+Replication

=DNA Replication=

= = DNA replication is known to be found within the second part of the interphase where a particular cell makes a precise duplication of the DNA in its cell. The process of DNA replication can be passed onto the next generation of cells (daughter strands). It allows you to copy the coded instructions and pass them from the other organism to the offspring. This characteristics and instructions make up the features of the offspring.
 * __ What is DNA replication? Write a good definition of this __**


 * Note: ** Exact replication of a DNA is really important since it carries the genetic information and it needs certain accuracy or it can destroy or makes the organism harmful. However mistakes do sometimes occur, that is how genetic disorders occur.



DNA replication is a process in which a “parent” DNA molecule is made and carries out its own information, and with this particular information the DNA molecule have, it is then duplicated into “daughter” strand. The process where the parental double DNA molecule is replicated known as Semi Conservative. It got its name since one of each of the parent strand is preserved and remains complete after replication process is done. Each copy contains one of the original strand and is paired up with another copy that is completely different and is a newly synthesize strand that is complementary.


 * Note: ** By parent DNA molecule is actually reffering to the sperm and egg in the male and female. the daughter is created through the mix of the two, each carrying 23 chromosomes and toghether creating the fetus.

(11) Complete the following:

Step 1: The two strands of the DNA separate. Each strand can be used as a pattern or template to produce a complementary strand, then form a new DLA helix. Step 2: Before replication, the length of DNA must be unwound and then held apart to expose the bases so that new nucleotide partners can bond to them.

__**Word Definitions**__ **Polymerase**: Polymerase is also one of the enzymes. Main function of Polymerase is the polymerization of new DNA and RNA, and getting old DNA and RNA's template in the process of replication and transcription. **Ligase**: Ligase is an enzyme that has function of catalyst for joining two large molecules by forming new chemical bond. **Okazaki fragment**: Okazaki fragment is a small molecule of DNA with single stand form during DNA replication. In Escherichia coli, they are between 1000 to 2000 nucleotides long, in eukaryotes they are 100 to 200 nucleotides long **Topoisomerase**: Topoisomerase is one of the enzymes that controls about winding of DNA. //__ Work cited __//
 * Helicase ** : Helicase is one of the enzymes that every single living organisms have. Main function of Helicase is to separate double helix of DNA by using ATP energy.There are DNA helicase and RNA helicase. DNA helicase is responsible for separating double-strand DNA into single-strand DNA allowing each strand to be copy.
