DNA Replication
What is the DNA Replication
Process of copying DNA before cell division in the nucleus
What are DNA base-Pairing rules
Adenine-Thymine and Cytosine -Guanine
What is Central Dogma of Genetics
Genetic information flows in one direction: From Dna to RNA and finally to protein
What type of bond holds the nitrogen bases together in DNA
What is Hydrogen bonds
What are the rungs of DNA
What is paired nitrogen bases
Each new DNA molecule retains one original parent strand
Semiconservative
What type of bond does helicase break when dna is unzipped
hydrogen bonds
what are the repeating units DNA is made of
Nucleotides which are Phosphate, deoxyribose suger, nigtrogenous bases
The strand of original DNA that is being copied
What is the Template strand
How many Chromosomes do humans have
What is 46
What is the replication Fork
y-shaped region where DNA is being separated
Purines have how many rings and what bases in DNA
2 double rings nitrogenous base, Adenine and Guanine
What breaks hydrogen bods and separates the strands
Helicase
The enzyme that adds a starting point to begin the DNA replication
What is Primase
How does proofreading help maintain genetic information?
Proofreading is crucial for accuracy in genes, polymerase play a huge role in correcting errors.
Template strand
Original parent DNA strand being copied for complementary daughter strand
In what region does the dna replication happen and which cell
nucleus, eukaryotic
What creates short RNA primers
Primase
"What is Hungry Tigers Choose Delicious Pizza Slices"
Helicase, Template strands, Complementary base pairing, DNA polymerase, Phosphodiester bonds, Semi-conservative
How does synthesis of the leading strand differ from synthesis of the lagging strand?
The leading strand synthesizes continuously whereas the lagging strand discontinuously synthesizes.
What are RNA primers
Short RNA sequence that provides a starting point for DNA polymerase
what 3 parts are nucleotides made of
Phosphate, deoxyribose sugar and nitrogenous bases
When DNA polymerase adds complementary DNA nucleotides in the 5'-3' direction
What is New DNA is synthesized
Which strand is a continous synthesis in the 5'3' directions
What is Leading Strand
Explain antiparallel at the for with DNA replication
The end that is 3'-5' would change to 5'-3' Leading Strand and the end that is 5'-3' would change to 3'-5' Lagging Strand
