Answer:
Si, esto es posible ya que para llegar a su forma madura el ARN mensajero sufre un procesamiento conocido como empalme alternativo donde su longitud se reduce drásticamente mediante la eliminación de regiones no codificantes (intrones) presentes en el trascripto primario
Explanation:
En células eucariotas, la transcripción refiere al proceso donde un gen es usado como templado para generar un ARN mensajero (ARNm) inmaduro conocido como pre-ARNm, el cual contiene regiones cortas codificantes (exones) y regiones largas no codificantes (intrones). Durante el proceso de empalme alternativo, también conocido como <em>splicing</em> alternativo, este pre-ARNm sufre un procesamiento mediante el cual los intrones son eliminados y los exones son retenidos y empalmados, con lo cual el ARNm maduro final reduce drásticamente su longitud original. En el caso arriba descripto, una proteína con 70 aminoácidos resultaría de la traducción de un ARNm maduro que posee 210 bases nucloetídicas, ya que cada triplete de nucleótidos o 'codón' corresponde a un sólo aminoácido agregado a la cadena polipeptídica durante la síntesis proteica en los ribosomas.
Answer:
20 molecules of ATP
Explanation:
Krebs cycle or also known as Tricarboxylic acid cycle (TCA) is the second stage of aerobic cellular respiration which occurs in the mitochondria. In the kreb cycle, pyruvate, which was synthesized in the first stage of cellular respiration (glycolysis) is broken down into carbon dioxide (CO2).
However, in the krebs cycle, two (2) ATP molecules is produced per glucose molecule that enters cellular respiration. Hence, according to this question, If 10 glucose molecules enter the Krebs cycle, (2 × 10) = 20ATP molecules will be possibly produced.
i'm too lazy to write that down for you but i can help you with a few points. Those are(i am relating this case to smoking):
>delicate lining of the lungs is damaged.
>cilia in the lining is damaged.
>since,cilia number is low, the lungs do not get cleaned often.
> spasms in the bronchi of the lungs, causing difficulty breathing.
>damaged lungs being much harder and more brittle.
The evolution of cells with nuclei and organelles
Answer:
C
Explanation:
Gymnosperms generally refer to a group of terrestrial, seed-producing vascular plants whose means of reproduction is an exposed ovule known as a cone.
There are 6 divisions within the gymnosperms, including cycads, ginkgos, and pinus (conifers). Gymnosperms are generally non-flowering and produce needle-like leaves. Their species are usually woody or perennial shrubs/herbs
This is <u>unlike the angiosperms</u> that are usually classified into 2, including the eudicots and the monocots. The division is based on the number of cotyledons or seed leaves carried by the plants in the group during germination.
<em>The correction option here would, therefore, be C. </em>
