Best Answer

DNA replicates itself. What happens is, with the help of enzymes, the nitrogenous bases of DNA break away from each other, then copy themselves and re-attach. This process forms 2 strands of identical DNA.

What is the complementary DNA strands?

A complementary strand of DNA contains the template information for the creation of a new copy of the other strand. How is it determined?


In genetics what does complementary DNA mean?

Complementary DNA (cDNA) is DNA that has been copied from an mRNA through a reverse transcriptase enzyme. cDNA contains a copy of the original DNA sequence that made the mRNA - but without the introns (as these are cut out to create mRNA).


Does mitosis copy the original strand?

Yes ,In mitosis , the original strands split into 2 parts with the help of enzymes forming "Y" shaped split .The exposed ends of the strand ,two new complementary strands are synthesised. So the duplicated strand of DNA contains 50% of the original strand and rest of the 50% is synthesised.


What is the complementary strand of DNA?

Yes, strands of DNA are complementary. Complementary implies that a sequence of nucleotides (ex. ATATG) is ordered in a way that it directly corresponds to another sequence of nucleotides (ex. TATAC). Since DNA is double stranded in most circumstances, barring mutagenesis, one strand would be pair with its complementary strand, thus forming the double stand.


How are two new DNA copies like the original DNA?

DNA (deoxyribosenucleic acid) replicates by a process called semi-conservative replication. In semi-conservative replication, one side of the DNA structure as acts a template and guide for the other strand to copy. Floating nucleotides then match up with the corresponding base (adenine base pairs with thymine, and cytosine base pairs with guanine). This pairing system is known as complementary base pairing. The fact that one side is copied exactly like the other, and the bases are always joined in the same sequence means the chances of a mutation is lessened, hence the two copies are exactly like the original DNA.

What is the difference between a Notarized copy of a document and a Certified copy of a document?

A notarized copy of a document is a copy of the original document that has been certified by a notary public as a true and accurate reproduction of the original. A certified copy, on the other hand, is a copy of the original document that has been certified as a true copy by an official or legal authority such as a government agency or court clerk. Both types of copies can be used for official purposes to verify the authenticity of the original document.
