Answer:
For regulating activities of cell.
Explanation:
Ad nucleus consists of genetic materials like DNA,RNA which is responsible for controlling and directing all the activities of cell.
Answer: When the DNA collected on the crime scene is being analysed in the forensic lab, the results will be inconclusive, because error in DNA transcription, particularly in mRNA encoding leads to inheritable phenotype change by reprogramming the transcriptional network, without changing the DNA. Transcription errors are brief with no long-term consequences. Due to mRNA being short-lived and the erroneous proteins are degraded. A decrease in transcription accuracy triggers cellular identity change.
Explanation: This is called epimutation, a heritable modification that results in the change of gene expression, but not the DNA sequence. Epimutation is not associated with DNA mutation, but is associated with the loss or gain of DNA methylation or other heritable changes of the chromatin.
Answer:
b. characterized by a lucid interval immediately after injury.
Explanation:
Epidural bleeding is the accumulation of blood between the dura (membrane lining the brain) and the skull. This bruise is typically caused by an acute head trauma that ruptures the middle meningeal artery. This bleeding is characterized by a lucid interval immediately after an injury to this region.
This bleeding has its most frequent location at the temporal lobe level, between the bone and the dura mater. It is due to rupture of the middle meningeal artery, usually by a temporal bone fracture. The artery runs on the outer surface of the dura, housed in a groove in the inner bone board. The fracture may clamp or cut the artery, leading to a bruise.
Answer:
DNA is not neccessarly produced, but is copied from when a parent cell divides into two daughter cells
Explanation:
If you mean where the DNA is stored, it is stored in the nucleus
