Hint: Complementary base pairing is very important in DNA molecule because it allows the base pairs to be arranged in the more energetically favourable way . it is essential in forming the double-helical structure of DNA. It is also important in replication of DNA as it allows semiconservative replication.
Why is complementary base pairing important in DNA replication quizlet?
Complementary base pairing is important because the hydrogen bonds between the bases hold the two strands of DNA together and because it serves as a way for DNA to replicate.
Why is complementary base pairing necessary for replication?
Complementary base pairing is important in DNA as it allows the base pairs to be arranged in the most energetically favourable way ; it is essential in forming the helical structure of DNA. It is also important in replication as it allows semiconservative replication.
Why is complementarity important in DNA replication?
Complementarity of DNA strands in a double helix make it possible to use one strand as a template to construct the other . This principle plays an important role in DNA replication, setting the foundation of heredity by explaining how genetic information can be passed down to the next generation.
Why is complementary base pairing important in DNA replication chegg?
Why is complementary base-pairing important in DNA replication? Chemicals or radiation may alter a nucleotide base in one strand of DNA ; this alteration may cause the altered base to pair with a nucleotide base other than its normal one.
Which of the following is an example of correct complementary base pairing in DNA?
Correct answer:
Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
How does complementary base pairing make DNA replication possible?
The base pairing rules make DNA replication possible because it allows DNA polymerase to create a new strand based on the template stand . ... DNA polymerase comes in and reads the sequence and assembles complementary nucleotides into a new strand based on the base pairing rules.
What are the rules of complementary base pairing?
Chargaff’s rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G) . A purine always pairs with a pyrimidine and vice versa.
What do you mean by complementary base pairing?
”’complementary base pairing. The standard arrangement of bases in nucleotides in relation to their opposite pairing, such as thymine being paired with adenine and cytosine paired with guanine .
How complementary base pairing is responsible for semiconservative replication?
Infer how complementary base pairing is responsible for semiconservative replication. One strand of DNA serves as a template to make the matching strand . The matching strand is made of complementary bases.
What is your basis in pairing the nitrogen bases of DNA?
In a DNA molecule, the two strands are connecting by hydrogen bonds between the nitrogen bases of each strand. According to the base-pairing rule, the purine adenine always pairs with the pyrimidine thymine , and the purine guanine always pairs with the pyrimidine cytosine.
What is base pairs in DNA?
There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T) . ... These bases form specific pairs (A with T, and G with C).
What is the steps of DNA replication?
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand , and the assembly of the new DNA segment.
Where does DNA replication happen in a eukaryotic cell?
| Prokaryotic DNA Replication Eukaryotic DNA replication | Occurs inside the cytoplasm Occurs inside the nucleus | Only one origin of replication per molecule of DNA Have many origins of replication in each chromosome |
|---|
What effect would this accidental change in the base sequences of the DNA molecule have on DNA replication?
What effect would an accidental change in the base sequence of the DNA molecule have on DNA Replication? The base wont match the original. The DNA would not match the original and is not correct .
Which is the correct base pairing in DNA?
A DNA molecule consists of 4 base pairs. They are adenine, guanine, cytosine and thymine—adenosine pairs with thymine using two hydrogen bonds. Thus, the correct base pairing is Adenine-Thymine : option (a).
