Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding

mRNA sequence, that specifies which of the 20 amino acids will be added to the protein during translation. Imagine that a prokaryote-like organism has been discovered in the polar ice on Mars. Interestingly, these Martian organisms use the same DNA → RNA → protein system as life on Earth, except that there are only 2 bases (A and T) in the Martian DNA, and there are only 17 amino acids found in Martian proteins.
Based on this information, what is the minimum size of a codon for these hypothetical Martian life-forms?
a. 2 bases
b. 3 bases
c. 4 bases
d. 5 bases
e. 6 bases
f. The answer cannot be determined from the information provided.

Answer:

C. NAD⁺  

Step-by-step explanation:

NADH is oxidized to NAD⁺ in Complex I of the Electron Transport Chain.

NADH ⟶ NAD⁺ + H⁺ + 2e⁻

The electrons continue through the Electron Transport Chain, and the NAD⁺ is used in three places during the Krebs Cycle.

(a) Isocitrate to oxalosuccinate

Isocitrate + NAD⁺ ⟶ oxalosuccinate + NADH + H⁺

(b) α-Ketoglutarate to succinyl-CoA

α-ketoglutarate + NAD+ + CoA → succinyl CoA + CO₂ + NADH

(c) Malate to oxaloacetate

Malate + NAD⁺  ⟶ oxaloacetate + NADH + H⁺

The NADH produced by these three reactions can then be used by Complex I in the Electron Transport Chain.

Answer:

1s2 2s2 2p4

Explicación:

1s2 2s2 2p4 es la configuración electrónica de la molécula de agua. En el agua, hay 10 electrones, dos de hidrógeno y ocho de oxígeno. La subcapa 2s contiene un máximo de 2 electrones, mientras que la capa 2p puede acomodar seis electrones. El átomo de hidrógeno pertenece al primer grupo y el átomo de oxígeno pertenece al sexto grupo de la tabla periódica. En la estructura de Lewis, un átomo de oxígeno está unido a dos átomos de hidrógeno en un ángulo de 104,45 grados. Existe un enlace covalente presente entre el hidrógeno y el átomo de oxígeno en el que ambos se vuelven estables. El oxígeno necesita dos electrones, por lo que forma enlaces con dos átomos de hidrógeno que tienen un electrón cada uno.
