Answer:
Mother- XXH
Father- XHY
Explanation:
The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.
The sequence AAU GGC UAC is composed of three codons each of which codes for a different amino acid.
AAU codes for the amino acid called threonine.
GGC codes for the amino acid called glycine
UAC codes for the amino acid called tyrosine.
So the chain will read threonine-glycine-tyrosine.
There are 64 possible 3 - letter combinations of DNA coding units A, C, G and T. Of these, there are three stop or non- sense codons that do not code for any amino acid, while the remaining 61 code for different amino acids.
Answer:
C) parfocal.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
A microscope is said to be parfocal if its lense is binocular and they can both be in focus.
Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.
<u>Complete Question:</u>
A nurse is caring for a 26-year-old client recently diagnosed with human immunodeficiency virus (HIV) and has a CD4 count of 150. The client needs an update on immunizations and asks which ones are needed. Which vaccines are required to comply with the recommended immunization schedule for a client with HIV?
a. Influenza; measles, mumps, rubella (MMR); varicella; and hepatitis A vaccines
.
b. Pneumococcal, MMR, influenza, and varicella vaccines
.
c. Diphtheria, tetanus, hepatitis A, and hepatitis C vaccines
.
d. Tetanus, hepatitis B, influenza, and pneumococcal vaccines.
<u>Correct Option:</u>
Tetanus, hepatitis B, influenza, and pneumococcal vaccines are required to comply with the recommended immunization schedule for a client with HIV.
<u>Option: D</u>
<u>Explanation:</u>
- Human immunodeficiency virus (HIV) is responsible for killing the WBC (white blood cells) that battle infection, as this virus destroys the immune system, which can follow certain cancers.
- While AIDS (acquired immune deficiency syndrome) is the last stage of HIV infection.
- In contrast to influenza vaccine delivery that avoids both viral and bacterial pneumonia, Streptococcus pneumoniae vaccination is suggested. The risk of invasive pneumococcal illness is strong for HIV-infected people.
- HIV patients obviously recover from influenza vaccination, the reaction of antibodies to seasonal flu vaccination is usually lower than among HIV-uninfected people.
