Answer:
None of the above.
Explanation:
GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.
The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.
Thus, the correct answer is option (d).
60 seconds
To ensure that all bacteria are removed from the puncture site for blood cultures, the site should be cleansed using friction for a minimum of 60 seconds.
<h3>Where exactly is the puncture site?</h3>
- The proper location must be cleansed and punctured with a lancet so that a drop of blood can be softly expressed before blood can be collected using a capillary tube.
<h3>But what constitutes a
suitable location? </h3>
- Finger: In both adults and children, the third or fourth finger is typically favored location as a puncture site
<h3>Where on the body does a skin puncture most frequently occur?</h3>
- The most frequently used site is the distal end of the third or fourth finger.
- Because the bone is so close to the skin surface, there is a higher risk of puncturing the bone at the very tip of the finger.
