Answer:
The phosphodiester connects the 3′ carbon of one nucleotide to the 5′ carbon of another nucleotide
Explanation:
The phosphodiester bond is a covalent bond where a phosphate group is attached to adjacent C through an ester bond, which is a consequence of a condensation reaction between the two sugar hydroxyl groups and the phosphate group.
The diester bond between phosphoric acid and two sugar molecules in the DNA and RNA skeleton binds two nucleotides forming polymers known as oligonucleotides.
The phosphodiester bond binds a C3` with a C5` in both DNA and RNA
(base)1-(sugar)-OH + HO-P(O)2-O-(sugar)-(base)2
------>
------> (base)1-(sugar)-O-P(O)2-O-(sugar)-(base)2
During the reaction of two of the hydroxyl groups in phosphoric acid with a hydroxyl group in two other molecules two ester bonds in a phosphodiester group are formed. A condensation reaction in which a water molecule is lost generates each ester bond.
Answer:
C6H12 (g) + 9 O2 (g) → 6 CO2 (g) + 6 H2O (l)
Explanation:
<span>When an atom or compound is oxidized, its properties change. For example, when an iron object undergoes oxidation, it is transformed because it has lost electrons. Unoxidized iron is a strong, structurally sound metal, while oxidized iron is a brittle, reddish powder. The diagram below illustrates what happens to an atom of iron as it is oxidized

The second row of the periodic table reflects second energy level which corresponds to 2 subshells obtained in this row.
Periodic table is arranged in rows and columns, the columns represents the group of the elements and the rows represents the energy level of the elements.
When we observe the second row of the periodic table, we will notice the following;
- The <em>second row</em> of the periodic table corresponds to <em>second energy level.</em>
- The maximum number of shells is <em>2.</em>
- The number of electrons in the second subshell increases from left to right
- The maximum number of electrons in the second subshell is 8, which is found in group zero (noble gases group).
Thus, we can conclude that the second row of the periodic table reflects second energy level which corresponds to 2 subshells obtained in this row.

Answer:
3.0002 moles
Explanation:
Data Given:
mass of NO₂ = 138.01 g
No. of moles NO₂ = ?
Solution
To find mass of sample mole formula will be used
mole formula
no. of mole = mass in grams / molar mass
Molar mass of NO₂ = 14 + 2(16)
Molar mass of NO₂ = 14 + 32 = 46 g/mol
Put values in above equation
no. of mole = 138.01 g / 46 g/mol
no. of mole = 3.0002 moles
no. of mole of NO₂ = 3.0002 moles
