CpG islands are found in most promoter regions of genes which are the DNA sequences responsible for the initiation of gene transcription.

CpG岛位于绝大部分启动子区域，是一组负责转录起始DNA序列。

In this case, the BCL1 gene from chromosome 11 ends up next to the immunoglobulin promoter on chromosome 14, which again upregulates its expression.

在这种情况下，11号染色BCL1因易位至14号染色，与14号染色免疫球蛋白启动子相邻，后者BCL1因表达。

In eukaryotes, if the introduced genes are derived from another organism, the resulting transgenic plants or animals can be propagated by normal breeding.

转因羊已经被生产出来，可以通过它们奶生产有价值蛋白。目因需要羊启动子（酪蛋白或乳清蛋白）以确保在乳腺中表达。从奶中纯化蛋白要比从培养细胞中纯化蛋白要容易多。

As a result, an the BCL2 gene from chromosome 18 is placed after the immunoglobulin heavy chain promoter on chromosome 14, and that results in overexpression of bcl-2.

因此，一个来自18号染色BCL2因被易位到14号染色免疫球蛋白重链启动子后，导致BCL-2过表达。

In this case, the Myc gene is translocated from chromosome 8 where it ends up adjacent to IgH promoter on chromosome 14 and again that upregulates its expression.

在这种情况下，MYC因从8号染色易位至14号染色，最终与14号染色IgH启动子相邻，这也它表达。
