How is a viral antigen, like EBV, recognized by T cells? A. An antigen fragment is presented within class I MHC to the T cell re

aniked [119]

Viral antigens like EBV are usually recognized by T cells involving an antigen fragment present within class I MHC to the T cell receptor.

Ebstein Barr Virus

The Epstein-Barr virus is a human herpes virus with unusual biological characteristics.

It lives in practically every human person in a dormant condition in resting memory B lymphocytes
It is also a strong transforming virus in vitro for B cells and is linked to numerous significant lymphomas, including Burkitt's, Hodgkin's disease, and immunoblastic lymphoma.

With the exception of the memory compartment, each stage of the cycle has been shown to be possibly controlled by the immune response.

Epstein-Barr virus (EBV), commonly known as human herpes virus 4, is a double-stranded DNA herpes virus that is extensively spread. It is the cause of infectious mononucleosis.

EBV is most usually transmitted by body fluids, particularly saliva. EBV, on the other hand, can transmit by blood and sperm during sexual intercourse, blood transfusions, and organ transplants.

EBV can be transferred by utilizing materials that have recently been used by an infected individual, such as a toothbrush or a drinking glass.

The virus is likely to survive on an object for at least as long as it is wet.
When you initially get infected with EBV (primary EBV infection), you might spread the virus for weeks or even months before you notice any symptoms.
Once the virus has entered your body, it remains dormant.

Hence, the correct answer is option A

What are villi, and in what organ system do they function?

svlad2 [7]

In the healthy individual, the walls of the intestine are covered by intestinal villi and their microvilli, which contribute to increase the absorption surface of the nutrients we ingest and lead them to the bloodstream so that they reach the organs according to their needs.

Analyze the results of a cross between two organisms that are both heterozygous for two different genes (AaBb). Use a Punnett sq

Xelga [282]

1) all the possible genotypes are also identified by color in the image below :AABBAAbB or AABbaABB or AaBBaAbB or aABb or AabB or AaBbAAbb
aAbb or AabbaaBB
aabB or aaBbaabbThere are 9 different genotypes in total. These can be achived by mixing the alleles of both genes of each parent (just like it's represented in the square).

2) there are 4 phenotypes
-one with an allele A and allele B that would dominate the other. (AABB, aAbB, for example)
- one with all alleles recessive- aabb
-one with the recessive alleles in the gene A but heterozygotic/homozigotic dominant for gene B ( for example: aaBB)
-one with the recessive alleles in the gene B but heterozygotic/homozigotic dominant for gene A ( for example: Aabb)

3) <span>probability of having offspring with the aabb genotype: 1/16
Just by looking at the punnet square, you can see that only one has the aabb genotype, in all the 16 possibilities.
