normal cell是体细胞,nucleus是细胞核,chromosome 是染色体,DNA molecule contains many genes的意思是DNA分子包含很多基因 allele是等位基因 讲明白一点:体细胞就是非生殖细胞,人体“体细胞”,除了精细胞和卵细胞其它都是normal cell。体细胞和生殖细胞的区别就是体细胞有46条染色体,生殖细胞(精子卵子...
rna是核糖核酸,是负责将dna携带的遗传信息进行表达和调控的媒介分子,一般有trna,mrna和rrna;gene就是...
contains many genes (hundreds to thousands) makes up a chromosome. The genes are arranged in a particular sequence and have a particular location on the chromosome (called its locus). In addition to DNA, chromosomes also contain many other chemical components. These chemicals ...
分别提取各种群10只甲虫(雌性比接近1:1)的DNA进行种群重测序。基因组采用Qiagen (Qiagen, Valencia, CA, USA) DNA纯化试剂盒提取DNA。用细胞破坏器(BeadBeater;BioSpec, Bartlesville, OK, USA)将相同样本混匀提取DNA,并遵循试剂盒的操作协议。最后,通过Qubit、Nanodrop和Femto Pulse machine对DNA数量和质量控制进行...
DNA You learned that the gene is the most basic unit of heredily.Genes control all the inherited fraits of living things, But where are genes found? Genes are locoted within our DNA. Almost every organism has DNA- plants, animals, and even microscopic bacteria. ...

Our catalog of W gene content reveals extensive duplications from all other chromosomes in the genome, with a relatively low percent of genes with persistent gene activity, which are enriched for func- tions in DNA recombination, the nucleosome, chroma- tin, and DNA binding. Our results suggest...
Allele Code: Imprinting, same exact gene may act differently depending on whether they are inherited from the paternal or maternal parent DNA methylation DNA甲基化,多位于CpG岛。 甲基化升高,p53降低,则易患肿瘤。 基因组印记取决于父源或母源。比如,甲基化印记没有正常写入,导致生长发育不能正常完成。
DNA breaks, which are repaired by nonhomologous end-joining or homology-directed repair. CRISPR/Cas9-mediated genome editing has been applied to generate cells or animals carrying precise gene mutations [5,6], including rearrangements [7,8] and deletion of chromosome segments [9]. We asked ...
