Question from alternative source

Numerous mutation types can arise in the body. Cystic fibrosis is a genetic condition attributed to various mutations in the CFTR gene. A specific mutation in the CFTR gene related to cystic fibrosis results in an earlier-than-expected termination of translation in the gene sequence. Which kind of mutation leads to this translation error resulting in cystic fibrosis?

  • silent
  • missense
  • nonsense
  • deletion

Answer:

Nonsense

Explanation:

Nonsense mutations refer to those that create a premature stop codon. The stop codons include UAG, UAA, and UGA. This situation could occur if a nucleotide substitution happens in the mRNA codon UAC (which codes for the amino acid Tyrosine) changing to UAG (which signifies a stop codon).

Upon reaching this codon, the translation machinery would interpret it as a directive to end translation. Consequently, the mRNA would be released, leading to a truncated version of the amino acid, which is likely not functional and could be flagged for destruction by the cell.

s2008m [1682]
The answer is option (d). Enzymes act as biocatalysts that can accelerate biochemical reactions within the body. Their functioning is optimal at specific pH and temperature conditions. Excessive heat or cold treatment can impair enzyme activity, with cold decreasing activity due to reduced molecular movement.

enyata [1788]
A. Calcium would be sent to the sarcoplasmic reticulum, causing contractions to stop. A muscle fiber ceases to contract the instant ATP is depleted. Furthermore, contraction halts when signals from the motor neuron stop, leading to the repolarization of the sarcolemma and T-tubules, thus closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are subsequently pumped back into the sarcoplasmic reticulum, allowing tropomyosin to once again obstruct the binding sites on the actin filaments.

Response:

Este es un ejemplo de dominancia incompleta. Se trata de un fenómeno genético que se manifiesta cuando un gen dominante no logra expresar su totalidad en el alelo recesivo en un alelo heterocigoto dominante.

Por ende, ambos rasgos se muestran, dando lugar a una fusión de los dos alelos para los colores (blanco y rojo). El alelo rojo dominante muestra dominio parcial sobre el alelo blanco recesivo, produciendo así el alelo completamente rosado.

Según la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas dominantes heterocigóticas deben ser R. El alelo blanco es recesivo (rr) y es enmascarado por el R rojo,

Sin embargo, al cruzar los dos alelos heterocigotos rojos:

Los fenotipos derivan en forma de

RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.

Esto ocurre porque el alelo rojo dominante no era total / completamente dominante sobre el alelo recesivo blanco en ninguno de los casos, resultando en un alelo rosa (el tercer fenotipo)
