    广州和天津保持着2016年的同样位势,分获综合排名第4和第5位。推动物业管理政府备案业务实现网上备案。

近日,江北新区盘城新居四组团经济适用房(拆迁安置房)项目举行开工仪式,项目可提供定向安置房1496套,总建筑面积约184000㎡,预计2020年完工。在待遇上,也开出了有竞争力的价码,比如杰出人才年薪200万元,安家费、住房,实行一事一议;领军人才年薪100万元,安家费100万元,给予175平方米产权住房1套,科研经费最高1000万元;拔尖人才年薪在30万元60万元不等,其中省部级及以上拔尖人才,学校给予产权住房,学科优秀拔尖人才则可以享受按市场价八折优惠购房等。

  看点02河西一地块闲置8年,成共享单车处理场南京河西核心区一幅地块闲置多年,现在竟然成为共享单车的处理场?该幅地块位于河西大街明基医院斜对面、缤润汇南侧,2010年被一家名为瀚海房地产的开发商拿下,拿地之后的8年时间里长期闲置,曾开工之后又停工。2018年实施建绿透绿90万平方米,每个区完成1个立体绿化示范项目,其后每年都会根据拆违拆临进度、城市建设等情况确定年度建设任务。

  中方保留根据实际情况对措施进行调整的权利,并将按照世贸组织相关规则履行必要程序。据了解,这是本市首次在用地性质上设出“负面清单”。

那些利率上浮较多的银行,本身按揭业务上就不占优势,占比很少,对市场的整体影响是有限的。

  于2016年6月开工,目前,主体结构全部封顶,现正在进行二次结构,内外墙粉刷,外墙保温铺贴施工。

  这一点从央行今天早上发布的消息就可以看出。春节前一居室价格在5000元上下,这一价格维持到了现在。

  报道还称,根据特朗普今日(当地时间22日)宣布的措施,美国财政部长姆努钦将制定新的投资限制条款,用于限制中国投资购买美国公司技术。

  他提醒,存量时代大家记住一点,城市更新才是未来的必由之路。林女士称,这里的房租每年都会上涨,但之前的涨幅一般都在200-500元之间,尚在可承受范围内。

  自驾方面,项目紧邻周邓公路、秀浦路、沪奉高速等城市主要道路,出行较为便捷。

  而在《住房租赁和销售管理条例(征求意见稿)》中,其第十条规定,住房租赁合同中未约定租金调整次数和幅度的,出租人不得单方面提高租金。

  在河西大街这幅地块的现场,整个地块被高高的围墙包围,东侧大门紧锁,西侧围墙上贴着一张“区施工工地扬尘污染控制公示牌”,常年被风吹日晒后公告牌四分五裂,从模糊的字迹中可以辨认出这幅地块为河西中部地区33-2号地块,建设单位南京瀚海房地产,施工单位江苏长江机械化基础工程公司。”该人士续称。

Photo List Chinese scientists perform genetic surgery to create first single-chromosome yeast

  Qin Zhongjun, a molecular biologist at the Center for Excellence in Molecular Plant Sciences, Shanghai Institute of Plant Physiology and Ecology, of Chinese Academy of Sciences, introduces his research in Shanghai, east China, Aug. 2, 2018. Brewer's yeast, one-third of whose genome is said to share ancestry with a human's, has 16 chromosomes. However, Chinese scientists have managed to fit nearly all its genetic material into just one chromosome while not affecting the majority of its functions, according to a paper released Thursday on Nature's website.

  SHANGHAI, Aug. 2 (Xinhua) -- Brewer's yeast, one-third of whose genome is said to share ancestry with humans, has 16 chromosomes. However, Chinese scientists have managed to fit nearly all its genetic material into just one chromosome while not affecting the majority of its functions, according to a paper released Thursday on the website of the journal Nature.

  Qin Zhongjun, a molecular biologist at the Center for Excellence in Molecular Plant Sciences of the Shanghai Institute of Plant Physiology and Ecology under the Chinese Academy of Sciences, and his team used CRISPR-Cas9 genome-editing to create a single-chromosome yeast strain, the paper said.

  Yeast is a type of eukaryote, which also includes humans, plants, and animals. Humans have 46 chromosomes, whereas male jack jumper ants have just one. It seems that the number of chromosomes of a eukaryote has no correlation with the amount of genetic information they possess, the paper said.

  "Our research shows that all the genetic information can be concentrated in just one chromosome," Qin said.

  In the past, researchers had fused two yeast chromosomes together, but no one had ever performed the type of extreme genetic surgery that Qin and his colleagues set out to do several years ago.

  Using the CRISPR-Cas9, Qin's team removed the DNA at the telomeres, the ends of chromosomes that protect them from degrading. They also snipped out the centromeres, sequences in the middle that are important to DNA replication, the paper said.

  First, they fused two chromosomes, then joined this product to another chromosome, and repeated the process in successive rounds until there was only one chromosome left, it said.

  Despite the genetic clipping and restructuring, yeast with one "super-chromosome" is similar to natural yeast in cell growth and gene expression, Qin said.

  "It overturns the traditional view that gene expression is determined by the structure of chromosomes," he said.

  By simplifying a complex genome system, Qin suggested that the research provides a new approach to studying the functions of telomeres.

  Earlier research found that the length of telomeres is related to early aging, the formation of tumors, and other diseases. Telomeres shorten as a cell splits, but if telomeres cannot shorten anymore, the cell dies.

  "A normal yeast genome has 32 telomeres of various lengths. It is too hard to describe each telomere's changes or reactions to drugs. But with only one chromosome and two telomeres, it will be easier to find the patterns," Qin said.

  The research may also pave the way for new man-made species in the future. "Yeast has great tolerance in genetic modification, and it is possible to add new chromosome segments to the genome. Researchers can make bolder attempts," he said.

  According to the paper, the change to the chromosome number has little impact on the gene activity. However, the single-chromosome strain produces fewer spores, which are reproductive cells for non-flowering plants, bacteria, fungi, and algae, in sexual reproduction.

  "The survival rate of spores produced by a natural yeast strain is 98 percent, while that of ours is 87.5 percent. The gap is not big," Qin said.

  The paper also said that Jef Boeke, a geneticist at New York University, and his team submitted their outcome for similar research. They condensed the yeast genome into a pair of chromosomes, but could not fuse the pair into one.

  One explanation for the difference is that Qin's team removed 19 repetitive stretches of DNA. Qin suggested these sequences might have interfered with the mechanism that cells use to fuse two chromosomes into one.

  The two teams worked independently from each other.
