解析 C。解析:本题考查植物遗传学中的基本概念。染色体(chromosome)是细胞中包含遗传信息(DNA)的部分。细胞质(cytoplasm)是细胞内除细胞核外的物质;基因(gene)是染色体上的特定片段,它是遗传的基本单位;线粒体(mitochondrion)主要与细胞呼吸有关,而不是包含遗传信息的部分。
Cell organelles represent the many smaller membrane-bound objects located within cells. Examples of cell organelles include ribosomes, mitochondria, endoplasmic reticulum, lysosomes, cytoskeleton, and Golgi complex. Each organelle serves a specific function and purpose for the cell....
this promotes and maintains the integral function of the cell. Thus, the nucleus is the core hub of the cell's activities. The nuclear envelope is innately impermeable to huge biomolecules; therefore, the nuclear channel and pores of the envelope are responsible to regulate active and...

aThis array CGH contains whole genomic regions including 356 major cell-growth related genes and over 40 known DNA copy number change disorders. 这个列阵CGH包含整体genomic地区包括356个主要细胞成长相关的基因和40已知的脱氧核糖核酸复制号码变动混乱。 [translate] ...
epithelial cells11, and the transitional basal cells at the SCJ25. Unfortunately, none of the above experimental models provide direct evidence that Barrett’s esophagus-like lesions derived from these cellular candidates can progress to advanced metastatic malignancy. Furthermore, the cell of origin ...
The sequence of the protein has been partially determined and, subsequently, overlapping cDNA clones containing the entire open reading frame of LF-B1 were isolated. The full-length cDNA encodes a 628 amino acid protein and directs the synthesis in vitro of a protein capable of binding DNA ...
The recombination DNA numerator and the transformation host cell null which contains thisDNA comprising a nucleotide sequence coding for at least a portion of the precursor polypeptide of ricin or a similar plant toxin. Recombinant DNA molecules containing such DNA as an insert, and genetically-...
The sunburn cell formation inhibiter and that it contains the DNAPROBLEM TO BE SOLVED: To provide a sun burn cell formation inhibitor or DNA damage repair promoter capable of improving the resistance of skin cell itself against the skin trouble caused by ultraviolet light and consisting of a ...
