Answer:
Histidine- Proline- Tryptophan- Stop codon
Explanation:
The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.
Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA
The following codons in the sequence specify the following amino acid:
CAC - Histidine
CCA - Proline
UGG - Tryptophan
UGA - Stop codon
Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.
N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.
Answer:
Cell copies its genetic material during the S-phase of the interphase during cell cycle.
Explanation:
- Cell cycle is broadly divided into two phases ; the interphase and the M-phase.
- M-phase is the dividing phase during which the karyokinesis and cytokinesis takes place.
- Interphase is the phase during which the cell prepares itself for division.
- It is further divided into G1, S and G2 phase.
- During G1 phase the cell prepares for DNA replication and the replication complexes assemble.
- The next phase is S-phase during which the DNA replicates itself and the genetic material in the cell doubles.
- The Next phase is G2 phase during which the DNA is scanned by DNA tepair complexes and errors in the replicated DNA are edited and repaired.
- At the end of G2 phase the cell prepares to enter M-phase.
Answer:
creación de un potencial de acción (despolarización), redistribución de iones a través del soma y finalmente repolarización (estado de reposo)
Explanation:
Las neuronas son células nerviosas capaces de transmitir impulsos en forma de corriente eléctrica. Una neurona está compuesta por dendritas, el soma o cuerpo celular y el axón. Durante la transmisión del impulso nervioso, el estímulo es en primer lugar recibido por las dendritas, recorre el soma y termina en el axón. El impulso nervioso se transmite a través de la neurona mediante un proceso de despolarización. Primero, se produce un aumento de la carga eléctrica en el interior de la membrana neuronal debido al aumento de iones de sodio en el interior celular. A continuación, se produce la redistribución de iones dentro del soma, con lo cual la señal se va transmitiendo a lo largo de la neurona. Finalmente, cuando el impulso ha terminado de recorrer el axón, se produce la repolarización o estado de reposo, donde se produce el restablecimiento de las concentraciones iniciales de iones y la neurona vuelve a su estado inicial.
