The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine (A) and thymine(T)or cytosine (C) and guanine (G).
DNA is self-replicating, plays a central role in protein synthesis, and is responsible for the transmission of hereditary characteristics from parents to offspring.
What else can I help you with?
If DNA molecule is compared to a spiral staircase what part make up the steps?
pairs of nitrogen bases
What nitrogen bases match in a molecule of DNA?
Adenine pairs with Thymine, and Guanine pairs with Cytosine in a molecule of DNA through hydrogen bonding. This base pairing is essential for the specificity and the complementary structure of DNA strands.
If the left chain of the DNA molecule has the nucleotide sequence CCGTAGGCC what is the sequence of the right chain of the DNA molecule?
The right chain of the DNA molecule will have a complementary nucleotide sequence to the left chain. For the sequence CCGTAGGCC, the complementary bases are as follows: C pairs with G, G pairs with C, T pairs with A, A pairs with T. Therefore, the sequence of the right chain will be GGCA TCCGG.
How many guanine bases a length of DNA will have if it has 26 cytosine bases?
In a double-stranded DNA molecule, the bases pair specifically: adenine pairs with thymine, and guanine pairs with cytosine. This means that for every cytosine base, there is a corresponding guanine base. Therefore, if there are 26 cytosine bases in the DNA, there will also be 26 guanine bases.
Name the four bases which may be found on a DNA molecule?
Guanine, Cytosine, Adenine, and Thymine. GC and AT pairs
What pairs of molecules form the steps in the DNA molecule?
nitrogenous bases
Is amino acid a double spiral molecule with pairs of nitrogen bases?
No its a DNA
If DNA molecule is compared to a spiral staircase what part make up the steps?
pairs of nitrogen bases
How many different types of bases are used to encode all genetic information in a molecule of DNA?
A DNA strand contains only 4 bases, which come in pairs. Adenine pairs up with Thymine, and Guanine pairs with Cytosine.
What nitrogen bases match in a molecule of DNA?
Adenine pairs with Thymine, and Guanine pairs with Cytosine in a molecule of DNA through hydrogen bonding. This base pairing is essential for the specificity and the complementary structure of DNA strands.
What is the order of bases of the rna molecule that is built from this DNA?
If the DNA sequence is ATCG, the complementary RNA sequence would be UAGC (A pairs with U, T pairs with A, C pairs with G, G pairs with C).
How many adenine bases would there be in a DNA molecule of 40 base pairs with 15 cytosine bases?
Since there are 15 cytosine bases, we can conclude that there are 15 guanine bases. That gives us a total of 30 bases, subtract that from 40 and you have 10 bases left. So then there are 5 adenine bases because there are also 5 more thymine bases.
How many billion paired molecule bases form human DNA?
the answer is four (4) billion pairs
Bonds that hold DNA bases together?
Hydrogen bonds hold together the nucleotide bases in a DNA molecule. There are specific base pairings: adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G), connected by hydrogen bonds. These bonds contribute to the stability and structure of the DNA molecule.
What Nitrogen bases floating in the nucleus pairs up with what on each half of the DNA molecule.?
A pairs with T ,G pairs with C , T pairs with A, G pairs with C during replication .
Name the four bases which may be found on a DNA molecule?
Guanine, Cytosine, Adenine, and Thymine. GC and AT pairs
How do the bases pair in DNA to form the double helix structure?
In DNA, the bases pair up in a specific way to form the double helix structure. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is important for maintaining the structure and stability of the DNA molecule.
