What is the DNA base pairing rule quizlet?

The base pairing rule is that adenine always is with thymine and guanine always bonds to cytosine. Describe the purpose of the hydrogen bonds in double stranded DNA. They hold the two strands of DNA together, but are weak enough to come apart during replication.

What is meant by the base pairing rules?

Base-pairing rule – the rule stating that in dna, cytosine pairs with guanine and adenine pairs with thymine add in rna, adenine pairs with uracil.

What is base pairing in biology quizlet?

Define base pairing. the principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine.

What is the base pairing rule for mRNA?

mRNA → DNA For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A) Adenine (A) is replaced by Thymine (T)

Which of the following describes the base pairing rules in DNA?

The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

What are the DNA complementary base pair rules?

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 are the basic principles of base pairing?

The rules of base pairing (or nucleotide pairing) are:

• A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T)
• C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

Why is the base pairing in DNA important 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. Replication occurs simultaneously at many origins along the DNA.

Why is the base pairing in DNA important?

Function. 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.
