Why might the expression of a transgene be especially abnormal in vertebrates with larger average size of genes and amount of heterochromatin in their genomes?

Answers

Answer:

position effect

Explanation:

Position effect refers to the consequences on the expression of a gene/transgene when it is inserted into a new genomic location, thereby explaining how transgene's behavior is affected by its genomic location. The differences in expression of the inserted gene/transgene are generally due to its proximity to regulatory sequences (e.g., enhancers). Species with larger genomes have many genes as well as long intergenic regions where heterochromatin may spread stochastically (randomly) in order to switch on/off the gene expression, thereby resulting in unstable phenotypes.

Answers

Answer:

The correct answer is - the ancient observation that someone who had recovered from the plague could safely care for those newly diseased.

Explanation:

Immunological memory is the ability of the body to recognize or identify and kill or remove the antigen, very quickly and faster, the body has previously encountered and developed an immunological response.

These memories are developed due to memory B cells or, memory CD8+ T cells and memory CD4+ cells developed by the first-time immune response. If someone who had recovered from the plague must have developed memory cells for the antigen and safer than those newly diseased.
