A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

∙ 9y agoIn DNA replication, the nitrogen bases adenine and thymine, and guanine and cytosine form base pairs. The base-pairing rule states that in DNA adenine pairs with thymine and guanine pairs with cytosine, and in RNA adenine pairs with uracil. The paired nitrogen bases are held together with hydrogen bonds.

Which bases pair together in human DNA?
Adenine pair up with thymine. guanine pair up with cytosin
How do dna bases pair up with mrna bases?
The mRNA bases are complementary to the DNA bases, and so form H-bonds when the DNA is single-stranded. DNA - mRNA A - U T - A C - G G - C
Expain how the nitrogen bases of the DNA ladder pair up?
simple adenine pairs with thymine and guanine pair with cystosine.
What best describes the correct pairs of DNA bases?
The nitrogenous bases will pair up as adenine/thymine and guanine/cytosine
Explain the function of replication?
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
What makes up the molecules at the end of DNA replication there are two identical DNA molecules?
During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these nucleotides are very particular about what they connect to. Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T). How the bases are arranged in the DNA is what determines the genetic code.
Flow chart of 8 steps of DNA replication?
The eight steps of DNA replication are: 1. DNA strands separate, 2. formation of replication fork, 3. RNA primase binds, 4. bases pair up, 5. elongation, 6. RNA primers removed, 7.termination, 8. repair. this can occur in any cell.
How do the nitrogen bases pair up during replication?
By forming matching hydrogen bonds.
Which bases pair together in human DNA?
Adenine pair up with thymine. guanine pair up with cytosin
What nitrogen bases floating in the nucleus pair up with on each half of DNA molecule?
A pairs with T ,G pairs with C , T pairs with A, G pairs with C during replication .
What is the process by which a DNA molecule is copied called?
dna replication. can be summarised as the two helical strands of dna unravelling through the action of enzymes and the corresponding nitrogenous bases of each being matched up (A-T, C-G) to form two identical strands
How do dna bases pair up with mrna bases?
The mRNA bases are complementary to the DNA bases, and so form H-bonds when the DNA is single-stranded. DNA - mRNA A - U T - A C - G G - C
Which four bases make up a molecule of DNA?
The bases in DNA are: Adenine(A), Thymine(T), Guanine(G), Cytosine(C) when they pair up: A-T, C-T
Which bases pair up with eatch other in DNA?
adenine - thymine cytosine - guanine
In DNA what does adenine always pair up with?
In DNA replication, adenine binds with thymine. In RNA, adenine binds with uracil.
Expain how the nitrogen bases of the DNA ladder pair up?
simple adenine pairs with thymine and guanine pair with cystosine.
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).
