What is the molecular formula for nucleic acids?
What is the molecular formula for nucleic acids?
Deoxyadenosine Monophosphate (dAMP): C10H14N5O6P. This chemical formula represents the sum of the purine base adenine (C5H5N5), deoxyribose(C5H10O4), and phosphoric acid (H3PO4), where condensation reactions at the molecule bond sites lose two water molecules (2H20). This is the DNA form.
What does 5 and 3 mean in DNA?
Each end of DNA molecule has a number. One end is referred to as 5′ (five prime) and the other end is referred to as 3′ (three prime). The 5′ and 3′ designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.
What is the formula for nucleotides?
The purines are adenine and guanine. The pyrimidines are cytosine, thymine, and uracil. The chemical formula of adenine is C5H5N5. Adenine (A) binds to thymine (T) or uracil (U).
Is there a formula for DNA?
The sum formula of AGCU is C38H48O26N15P3. The deprotonated formulae are C39H47O22N15P33− (dAGCT) and C38H45O26N15P33− (AGCU)….Calculating the sum formula.
| Base | Formula (DNA) | Formula (RNA) |
|---|---|---|
| C | C9H12O6N3P | C9H12O7N3P |
| T | C10H13O7N2P | (C10H13O8N2P) |
| U | (C9H11O7N2P) | C9H11O8N2P |
What are the four enzymes involved in DNA replication?
DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
What is plus and minus strand DNA?
in a single-stranded DNA virus, a plus strand is one contained in the virus particle or any strand having the same base sequence. A minus strand has a base sequence complementary to the plus strand; mRNA can be transcribed from the minus strand.
What does G pair with?
Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
What are the atoms in a nucleic acid?
Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).
What 3 molecules make up a nucleotide?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
