Which bases pair together in a DNA molcule?
Adenine pairs with thymine. and Guanine pairs with cytosine.
What do we called nucleotides that pair of together?
Complementary base pair
What bases forms a true complementary pair?
cytosine and guanine
How do bases pair in DNA?
Both strands of DNA made of nucleotides come together and start making a helix which makes the bases pair up while the DNA strands are being twisted around like the helix. In the canonical Watson-Crick DNA base pairing, adenine (A) forms a base pair with thymine (T) and guanine (G) forms a base pair with cytosine (C).
What is pair of complementary nitrogenous bases in DNA?
There are four nucleotides and each links to another specifically based on the number of hydrogen bonds it makes. A bonds with T (2 hydrogen bonds) and G links with C (3 bonds).
Which bases pair together in DNA?
In DNA, the bases that pair together are adenine (A) with thymine (T), and cytosine (C) with guanine (G).
What is a molecule that consists of two complementary strands?
DNA is a molecule that consists of two complementary strands, which are held together by hydrogen bonding between nucleotide bases. The bases on one strand pair with the bases on the other strand in a specific manner: adenine with thymine and guanine with cytosine.
Which bases pair together in human DNA?
Adenine pair up with thymine. guanine pair up with cytosin
What shows how bases pair in complementary strands of DNA?
Bases pair in complementary strands of DNA through specific hydrogen bonding interactions: adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C). This base pairing allows for the accurate replication of DNA during cell division.

How are complementary sequences held together?
Complementary sequences of DNA, which pair the nucleotide base adenine with thymine, and cytosine with guanine, are held together by hydrogen bonds. The nucleotide bases are partially made up of nitrogen, oxygen and hydrogen molecules bonded together. On each base, one nitrogen is bonded to a hydrogen. Nitrogen is very electronegative, meaning that it pulls hydrogen's electron closer to it and becomes slightly negative. This leaves a slightly positive hydrogen sticking out. Each base also has an oxygen sticking out with a pair of electrons ready for bonding. These electrons can not bond with hydrogen, as hydrogen is already in a bond with nitrogen and can only form one bond. However, they are negatively charged and strongly attract the slightly positive hydrogen on the opposite complimentary base. This pattern means that two hydrogen bonds are formed each pair of complementary bases, holding complementary sequences together.
How are the bases in the base pair held together?
hydrogen bonds
