|what does DNA stand for?||Deoxyribonucleic acid|
|where is DNA found?||in the nucleus|
|what is the function of DNA?||it hold the herditary genetic information. It is what chromosomes are made of|
|What makes up DNA?||it is made up of repeating nucleotide subunits|
|what are the four types of nitrogenous bases?||Adenine, Guanine, Cytosine, Thymine|
|what does Adenine pair with?||Thymine|
|what does Cytosine pair with?||Guanine|
|who suggested the double helix structure?||James Watson and Francis Crick|
|what is a double helix structure?||it is two spiral wound strands around each other|
|what is chargaff's rule state?||it states that DNA has a 1:1 ration of pyrimidine and purine bases. I.e the amount of A = amount of T and the amount of C = amount of G|
|How are DNA stands complementary?||the bases on one strand match up with the bases of the other stand|
|which sugar is present in DNA?||deoxyribose|
|what is the central dogma?||this is the process wheregenes flow into proteins through translation and transcription|
|what are pyrimidines?||cytosine and Thymine|
|what are purines?||Adenine and Guanine|
|what is the structure of a nucleotide?||it consists of a phopahate group, a deoxyribose sugar ans a nitrogenous base|
|what is DNA replication?||it is the process by which DNA copies itself|
|when do replication happen?||it happens when chromosomes copy themselves before mitosis and meiosis|
|what is semi-conservative replication?||this is when each piece of DNA is made up of 1 older strand and 1 newer strand|
|Does DNA leave the nucleus?||DNA never leaves the nucleus|
|what is RNA?||RNA is a copy of the DNA that can safely go outside the nucleus into the cytoplasm|
|what does RNA stand for?||ribonucleic acid|
|How many stands does RNA have?||one|
|what is the replication folk?||it is a Y shaped region where the parentak strands of DNA are unwound|
|what is the leading strand?||it is the strand that runs in the 5' to 3' direction|
|what is the lagging strand?||it is the strand that is replicated in the 3' to 5' direction, and it is synthesied with the help of Okazaki fragments|
|what are Okazaki fragments?||they are segments of the lagging strand as it is synthesised|
|what does DNA polymerase?||it is reponsible for the catalysis of a new strand|
|what does DNA helicase do?||it "unzips" or breaks the hydrogen bonds between the bases of the strands|
|what does primase do?||primase is an enzyme that copies copies DNA templates stands by making an RNA strand complementary to it|
|what the function of DNA polymarase III?||it catalyzes the chemical reaction for polymerization of necleotides. it begins the synthesis of DNA in the 5' to 3' direction|
|what's the function of DNA polymarase I?||it synthesizes nucloetides onto primers on the lagging strand, forming okazaki fragments.|
|what's the function of ligase?||it connects the okazaki fragments together, an area that DNA pol I is unable to synthesis|
|what's the function of telomerase?||it catalyzes the lengthing of telomarase|
|What is DNA ligase 1 ?||Is an enzyme that in humans is encoded by the LIG1 gene. DNA ligases are important tools for DNA replication and repair in living organisms.|
|What is DNA polymerase I (or Pol I) ?||Is an enzyme that participates in the process of prokaryotic DNA replication.|
|What is DNA polymerase II (Pol II) ?||Is a prokaryotic DNA-Dependent DNA polymerase encoded by the PolB gene.|
|What is DNA polymerase III ?||DNA polymerase III Holoenzyme is the primary enzyme complex involved in prokaryotic DNA replication.|
