Answer:
Option A, The lymphocytes express antigens specific for the antibodies in the assay
Explanation:
The options for the question are
a) The lymphocytes express antigens specific for the antibodies in the assay
b) The lymphocytes do not have antigens specific for the antibodies in the assay
c) This is not a valid method for identifying HLA agents.
Solution -
The aim of conducting this assay is to use the ability of the microlymphocytotoxicity assay (CdL) to detect the antibodies specific to the antigens based on the complement dependent assay.
The B and T lymphocytes are tested at both warm and cold temperatures and then the result obtained is compared with other non –complement based test results. HLA-ABC alloantibodies are weak in reactivity and specific to B cell hence they can be identified only through the CdL assay.
Hence, option A is correct
Answer:
The correct answer is e. the ability to replicate the genetic information accurately for the next generation
Explanation:
As there are chances of existence of life in the universe but we can not say that they will have the same type of genetic material as we have but the ability of replication of genome and the ability to pass the genetic information accurately to the next generation will be the most common feature in all genome because without genome replication and transfer life can not evolve and proceed on any planet.
Therefore replication and genetic information transfer to the next generator is necessary. So the right answer is e.
