DNA是分子,是基础.基因由一串DNA组成.染色体又由很多很多DNA(包括很多基因)外加蛋白质构成. DNA就像是字母 而基因就是词 染色体就是句子. 其实这个比喻不恰当.应该这样比:一根长绳子(DNA),很长.中间的某一节(基因).把这根绳子绕在罐头上,绕很多罐头,绕完后在仔细堆放好,就是染色体了. 分析总结。 把这根绳...
DNA是分子，是基础。基因由一串DNA组成。染色体又由很多很多DNA(包括很多基因）外加蛋白质构成。DNA就像是字母 而基因就是词 染色体就是句子。其实这个比喻不恰当。应该这样比：一根长绳子（DNA），很长。中间的某一节（基因）。把这根绳子绕在罐头上，绕很多罐头，绕完后在仔细堆放好，就是染色体了。
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...
那么gene（基因)就是还有遗传信息的序列，也就是说，DNA还有RNA是由无数基因组成的，allele是等位基因，...
High molecular weight DNA for Pacific Biosciences (PacBio, Menlo Park, USA) Single-Molecule Real-Time (SMRT) continuous long-read (CLR) sequencing was isolated as described in Supplementary Note 1. PacBio library preparation and sequencing were performed at the University of California Davis Genome...
When an allele is favoured in one sex and selected against in the other. Hemizygous A diploid genotype that has only one copy of a particular gene, as in X chromosome genes in a male, or when the homologous chromosome carries a deletion. ...
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 ...
DNA fragments > 20 kb were selected for library preparation using BluePippin (SAGE). The PacBio library was prepared using the SMRTbell Template Prep Kit-SPv3 following the manufacturer’s instructions (Pacific Biosciences, Menlo Park, CA, USA) and was sequenced on the Pacific Biosciences ...
which were further cultured to 4- to 16-cell embryos for DNA-FISH analysis or transferred into recipients. WT, embryos without injection of Cas9 mixture.cBlastocyst rate of embryos generated by gene editing. The experimental group (Rbmy1a1,Ssty1,Ssty2) showed no difference compared to the co...
While sex chromosomes carry sex-determining genes, they also often differ from autosomes in size and composition, consisting mainly of silenced heterochromatic repetitive DNA. Even though Y chromosomes show structural heteromorphism, the functional significance of such differences remains elusive. Correlative...
