(03.05 MC) In which of the following ways is DNA replication different from DNA transcription? (2 points) New cells can only be
Softa [21]
The correct option is D.
Transcription is the process by which the information in a DNA molecule is copied into an mRNA strand. Replication is the process by which two new strands of DNA are formed from a single parent DNA. Both the DNA and the RNA are composed of four different bases, three of the bases are the same while one is different for the DNA and RNA. It is only the RNA that has uracil while it is only the DNA that has thymine. Thus, Uracil is involved during the process of transcription since it is an mRNA strand that is formed while thymine is the one involved during the process of replication since it is a DNA molecule that is formed.<span />

Andrei [34K]

Answer:

músculo cardíaco

Explanation:

Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.
