What is complementary base pair?

Answer 1

The complementary means that if you know the sequence of bases in one strand, you'll know the sequence of bases in the other strand. For example, if the base sequence of bases in one DNA strand is A-C-T, the base sequence in the complementary strand will be T-G-A, as shown here http://www.ric.edu/faculty/jmontvilo109graphicsdnaandrnadnastructure.gif

it is urasil for RNA. It is adenine for DNA

CORRECTION.
It is uracil for RNA, thymine for DNA.

Answer 2

DNA: A and T base pair together or G and C base pair together

RNA: A and U base pair together or G and C base pair together

- Adenine (A)

- Guanine (G)

- Cytosine (C)

- Uracil (U)

Answer 3

The pairing of complementary base paring is the bonding of (adenine and thymine, guanine and cytosine) via hydrogen bonds from opposite strands of a double stranded nucleic acid (such as DNA or RNA), thereby holding the double-stranded nucleic acid together.

Answer 4

In DNA complementary base parings are the DNA monomers or bases, Thymine with Adenine (or Uracil and Adenine in RNA) and Guanine with Cytosine. Only these paring occur, the base thymine doesn't complement guanine or cytosine so doesn't pair with it.

Thymine with Adenine forms 2 hydrogen bonds and Guanine with Cytosine forms 3 hydrogen bonds (these difference in the number of bonds formed is the reason for the complentary nature).

Answer 5

Base pair complementarity ensures faithful DNA replication. Remember that a base can only pair with a definite pair and not with just about any base therefore this ensures high fidelity of replication. If guanine can only pair with cytosine the same way that adenine can only pair with thymine then the copying of the DNA will be accurate.

Answer 6

There are four base pairs in a double DNA strand, and complimentary base pairs are the two on either strand that connect to eachother. Though the molecule can loop and connect to complimentary base pairs in other parts of the molecule, it's always adenosine connecting to tiosine and Adenine (A) connecting to Thymine and Guanine (G) to Cytosine (C) as far as DNA is concerned.

So A and T would be complimentary base pairs and C and G would be too.
