I believe it's 1. Duplication of DNA has already happens.
Answer: Multiple forms of documentation are used at the scene of a mysterious death, it gives the summary of the investigation at a glance.
Some of these forms of documentation are Note taking, Sketching, Photography or Videography.
NOTE TAKING; Field notes are always personal to the person that made/took them,
They are the most personal and readily available record of the crime scene search.
Field notes are the most important steps in documenting a crime scene initially.
SKETCHING; Sketching,as unimportant as it may seem has a potential benefit of complementing photograph and videos and also,crime scene sketch shows certain details about an investigation better more than a photograph.
PHOTOGRAPHY/VIDEOGRAPHY; Photographs and videos are excellent sources of evidence of a crime,they are good evidence to document a crime scene.
They can either be in the form of film or digital format.
It is always adviceable to employ digital photography/videography as it fast becoming a standard in crime scene documentation rapidly.
Answer:
A) It is the recognition site for a specific transcription factor
Explanation:
Promoter is non-coding DNA sequence responsible for initiation of transcription, as a first and most import step in the regulation of gene expression. Usually changing of promoter nucleotide sequence can lead to loss of promoter function.
In eukaryotic cell, promoter is associated with with other regulatory regions such as enhancers, silencers, insulators. The structure of eukaryotic promoter includes the binding site for the enzyme RNA polymerase, site for the binding of regulation factors (such as TATA box), the transcription start site.
Answer:
The correct answer is a cancerous tumor.
Explanation:
Density-dependent inhibition refers to the phenomenon in which the crowded cells stop proliferating. In the process, the group of cells present in a region force competition for space, nourishment, and growth factors. Thus, when the cells are clumped together, they receive the signals to stop dividing further. Thus, in density-dependent inhibition, when the density is high no division of cells takes place.
Density-dependent inhibition is a process in which the growth of the cells is restrained to a specific limit of density, after that the growth gets prevented, probably due to cell-cell contacts. On the other hand, the tumor cells generally do not possess density-dependent inhibition, due to this, the cancer cells show unlimited growth without getting ceased. Therefore, in the given case, the source of the tissue sample is primarily a cancerous tumor.
Answer:
sensory/motor
Explanation:
Dorsal roots contain axons that bring <u>sensory</u> information to the spinal cord and ventral roots contain axons that bring <u>motor</u> commands away from the spinal cord.
