During DNA replication each strand of DNA is used as a template to produce a complementary strand of DNA. This process is shown below. Which base will attach to location 1?
Guanine
How do the rules of base pairing help DNA replication happen with few mistakes?
The base pairings are ALWAYS the same; where Adenine pairs with Thymine and Guanine pairs with Cytosine. As long as there is one strand of DNA with these bases as templates, the other strand can always be determined. DNA replication always uses an old strand and uses it as the template for creating the new strand. Ex: ATTGCCGTAAT is the old strand of DNA. The complimentary strand is TAACGGCATTA. The base pairings will always be the same because of the DNA polymerase which checks the pairings and fixes any mistakes. It is very rare for mistakes to occur.
How does a nitrogenous base pair with DNA?
In DNA, nitrogenous bases pair according to specific rules known as complementary base pairing. adenine(A) pairs with Thymine (T) and Cytosine(C) pairs with Guanine (G). This is due to the hydrogen bonds between these bases: two between A and T, and three between C and G. These pairings allow the double helix structure of DNA and enable the accurate replication of DNA during cell division.
During DNA replication what?
DNA replication produces two copies of the DNA.
How does replication ensure that identical copies of DNA are made?
The DNA is a double-helix, two strands of nucleotides that are required to pair up in a particular way: adenine to thymine, and guanine to cytosine. During replication, this pairing code is kept perfectly, ensuring that each copy is identical.
What two extra guanine bases are added to the DNA during DNA replication what mutation is this?
This is a frameshift mutation and will render the rest of the DNA sequence useless.

Guanine

frameshift mutation
What is copies during replication?
A cell's DNA is copied during replication.
DNA is copied during a process called?
Replication.
What separates the DNA strands during replication?
That would be called the Replication Fork
In what part of the cell does the replication occur?
DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.
How do base pairing rules explain how a strand of DNA acts as a template during DNA replication?
the 4 nucleotide bases are adenine, guanine, thymidine & cytosine. In a double stranded DNA adenine always pairs with thymidine & guanine always pairs with cytosine. so knowing the base pairs in strand we can determine the base pairs of the other strand. hence DNA strand acts as a template during DNA replication.

because it just is
