The miRNA functions as a guide by base-pairing with target mRNA to negatively regulate its expression.
Whereas, CRISPR technology is a simple yet powerful tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function. Its many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops.
The options provided for the question above are as follows:
A. Respiratory tract illnesses
B. Skin infection
C. Acute infectious diaherea
D. Intestinal infections.
The correction option is A.
Respiratory tract illnesses account for the majority of sickness that occur in child care settings. Such infection include those that affect the lower and the upper respiratory tracts; examples include: otitis media, sinusitis, bronchiolitis, pneumonia, etc. Children who attend out of home child care has greater risk of contacting these diseases.
Cell division begins along the cell's equator, between the two chromosomal poles that form during nuclear division. Microflients help the cell lay down new membrane and divide it into two daughter cells.
Cell X is likely a prokaryotic cell. Option B) is the correct answer.
<u>Explanation</u>:
- The prokaryotic cells are present in unicellular organisms such as bacteria and lack Nucleus in it. The cell X is not filled with x-mark in the nucleus.
- The prokaryotic cells consist of the cell membrane, cell wall and a genetic material composed of DNA. All these are marked with x-mark for cell X.
- Chloroplasts are not present in prokaryotic cells and the space for it is left blank in cell X without the x-mark.
- This information clearly shows that prokaryotic cell structure is viewed likely in cell X.
