Cytosine should not ever pair with thymine, for two major reasons:
Cytosine and thymine are both pyrimidines, meaning they contain a single sugar, whereas adenine and guanine are purine and contain a two-ringed sugar. If cytosine were to pair with thymine (or another cytosine) it would throw off the shape of the DNA double helix.
Cytosine wants to form three hydrogen bonds, and thymine can only form two.
Thus, under normal circumstances, cytosine will never be paired with thymine.
What else can I help you with?
Is A C a legitimate base pair?
Not in DNA. In DNA the only base pairs are A-T and C-G. RNA can form non-canonical base pairings, so you might get some AC in RNA structures.
Can base C ever pair up with base T?
In DNA, base cytosine (C) pairs with guanine (G) through three hydrogen bonds, while thymine (T) pairs with adenine (A) through two hydrogen bonds. Therefore, base C does not pair with base T in standard DNA base pairing rules. However, in certain experimental or altered conditions, non-canonical pairing might occur, but this is not typical in natural DNA structures.
How many letters does DNA have?
A,C,T,G "A" and "T" always pair "C", "G" always pair
Is Each strand in the double helix is identical to the opposite strand?
Each strand in the double helix is complementary rather than identical to the opposite strand. The bases in one strand pair up with specific bases in the opposite strand according to the base pairing rule (A with T and C with G). This complementary base pairing allows each strand to serve as a template for the synthesis of a new strand during DNA replication.
Total number of different arrangements in DNA molecule with two base pairs?
There are four different arrangements in a DNA molecule with two base pairs: adenine-thymine (A-T), thymine-adenine (T-A), cytosine-guanine (C-G), and guanine-cytosine (G-C). Each base pair can be oriented in two different ways, resulting in a total of four arrangements.
Which DNA strand can base pair with a-t-g-c-t-a?
T-A-C-G-A-T
Is A C a legitimate base pair?
Not in DNA. In DNA the only base pairs are A-T and C-G. RNA can form non-canonical base pairings, so you might get some AC in RNA structures.
What is meant by -base paring- and which base pair with which?
It means which nitrogen base pairs with the other Nitrogen bases: A-t T-a C-g G-c
Can base C ever pair up with base T?
In DNA, base cytosine (C) pairs with guanine (G) through three hydrogen bonds, while thymine (T) pairs with adenine (A) through two hydrogen bonds. Therefore, base C does not pair with base T in standard DNA base pairing rules. However, in certain experimental or altered conditions, non-canonical pairing might occur, but this is not typical in natural DNA structures.
What is the base pair rule for RNA?
A goes to U and G goes to C. DNA its A=T G=C.
What are chargaffs base pair rules?
Chargaff's base pair rules state that in DNA, the amount of adenine (A) is equal to thymine (T), and the amount of cytosine (C) is equal to guanine (G). This is known as complementary base pairing, where A pairs with T and C pairs with G.
What would indicate a base paring an A paired with a T or a C paired with a G?
Which of the following would indicate a base pairing mutation in DNA?1) an A paired with a T2) a C paired with a G3) a G paired with a T4) all the above are improrer base pairsThe correct answer is #3A should pair with T and G should pair with CIf A paired with C or G paired with T it would be a base pairing mutation.
What is the complimentary DNA base pair to ATCG?
TAGC. A pairs with T, G pairs with C.
Cytosine will form a base pair only with?
Cytosine (C) and Guanine (G) pair, as do Adenine (A) and Thymine (T).
What are the building blocks of a nucleotide?
A nucleotide consists of a base pair ( A with T, C with G) with a sugar phospate molecule
How many letters does DNA have?
A,C,T,G "A" and "T" always pair "C", "G" always pair
What are the base pair combinations of the DNA?
Adenine and Thymine A = T, Cytosine and Guanine C = G.
