A group led by Shunsuke Ishii at the RIKEN Tsukuba Institute in Japan studied the protein ATF2 in Drosophila. They found that this protein is needed for the formation of heterochromatin - tightly packed DNA-protein complexes that block the expression of certain genes. Stress causes phosphorylation of ATF2, dislodging it from heterochromatindoi:10.1038/475008dNature Researc...

Step-by-Step Solution:1. Understanding the Question: The question asks about genes that are located close together on a chromosome. We need to identify the term that describes this relationship.2. <stron
This finding led us to assume that these genes are located at different loci on the chromosomal region. However, this notion has not yet been confirmed by molecular evidence. In this study, to narrow down the location of the monoecious gene, we developed 19 AFLP markers linked to the gene...
[{Blank}] genes are located on the same chromosome and are inherited together. The distance between them can be found by measuring how frequently they [{Blank}]. A) Linked; mutate B) Unlinked; mutate C) Unlinked; cross-over D) Linked; cross-over ...
Inherited traits are passed on from parents to offspring through. A. genes B. environment C. lifestyle D. diet 相关知识点: 试题来源: 解析 A。本题考查遗传的方式。遗传性状是通过基因从父母传给后代的。环境、生活方式和饮食可以影响性状的表现,但不是遗传的方式。
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
Hereditary, also called inheritance, are the biological characteristics, where the traits from the parents get transferred to their offspring. The inheritance occurs via either sexual or asexual reproduction. Genes are the basic building blocks of hereditary which are located inside a chromosome...
What are genes composed of?Question:What are genes composed of?GenesDNA (short for deoxyribonucleic acid) is often referred to as the blueprint of the cell. Note that chromosomes, are comprised of DNA, which contains the code for protein synthesis and in turn traits, such like eye color and...
