Are SA citizens vaccinated against yellow fever? give two reason for your answer.
Brut [27]
South African people are vaccinated with Yellow fever. First, SA is strict in the implementation proof of vaccination in travelers coming in the country. The vaccination card must show vaccination at least ten days prior to travel. This is to prevent reintroduction of the disease to SA people. Second, In the list of Center for Disease Control, South Africa is not included in the countries with an endemic Yellow fever which means that the disease is wiped out if not controlled through vaccination.

4. There are a variety of receptors and second messenger systems in cells that in many cases exhibit cross-talk with each other
frutty [35]

Answer:

These 3 receptors are different from each other. They do differ from each other by their location and function.

1. Testosterone receptor :  It is an Androgenic receptor

2. Ferrotransferrin receptor :  It acts as an element-binding protein which is iron responsive.

3. Fibroblast growth factor :  It acts as a growth factor.

Explanation:

1. Testosterone :

Location- Xq 11-12 in the X chromosome.

Function-  

  1. maintains male skeletal integrity by osteoblast and osteocytes.
  2. maintains female sexual, somatic and behavior.
  3. develops male sexual characters.

2. Ferrotransferrin :

Location- chromosome 3q21

Function-

  1. intakes iron in the cell.
  2. maintains the cellular iron equilibrium.
  3. post-transcriptional modification.  

3. Fibroblast (growth) :

Location- chromosome 4p16.3

Function-

  1. helps in bone development.

In STR profiling, PCR is used to obtain enough DNA to then detect the number of STRs at I specific loci.​
Licemer1 [7]

PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.

<h3>What is Short Tandem Repeat (STR) profiling?</h3>

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.
