What is the role of the nucleus in cell division? Why does a cell undergo mitosis? What functions do centrosomes have during mitosis? What is the significance of cell theory to biology? What is passage number in cell culture? What are the functions of cells in the human body?
Translation in the nucleus is a long-standing controversial issue with unclear physiological importance. Recent studies show that antigenic peptides for immune tolerance are derived from translation initiated at non-AUG codons of precursor mRNAs in the nucleus. It is therefore time to take a fresh ...
The purpose of meiosis is to A. help an organism grow larger B. produce the gametes (sex cell) C. duplicate the nucleus D. check for genetic mutations How does meiosis play a role in heredity? Briefly explain the difference between the outcome of non-disjunction during meiosis I vs. meios...
网络谣言和网络话语权总是相伴相随的,在赋予普通网民内容生产和传播权力的同时,谣言生产机制也就此诞生。部分谣言是网民无意识中传播的,相比之下,有组织的网络水军及其谣言无疑更可怕,他们混淆着视听,裹挟着民意,伤害着整个社会最柔软的那部分良善机理。总之,无论是无意识的谣言还是有组织的谣言,当其以社会舆论和民意...
Somatic cell nuclear transfer (SCNT) is a technically and biologically challenging procedure during which a differentiated committed nucleus undergoes rapid reprogramming into the totipotent state in a few hours. SCNT can be utilized to generate patient- and disease-specific embryonic stem cell (ESC) ...
Interphase- the longest phase of the cell cycle where a cell is growing, replicating its DNA, and preparing for cell division. M-phase - the mitosis phase where a cell dissolves its nucleus, organizes its duplicated chromosomes and genetic information in the middle of the cell where they are...
Proteins can have a variety of uses in the cell and are important for biological functions.What Is DNA? Genetic material is found in the organelle titled the nucleus in eukaryotic cells, and it is freely floating in the cytoplasm of prokaryotic cells. Genetic material is found in the form ...

a胃FSH免疫反应阳性物质分布于壁细胞和主细胞细胞质内,细胞核呈阴性反应,阳性物质呈绿色荧光 The stomach FSH immune response masculine material distributes in the wall cell and the main cell cytoplasm, the cell nucleus assumes the negative reaction, the masculine material assumes the green fluorescence[tra...
What is the purpose of the nucleus pulposus? During photosynthesis, where do the H+ ions come from? Why is oxygen needed for oxidative phosphorylation? Why it is important that pepsin functions at a low pH? Why does succinate dehydrogenase use FAD?
