aThe nucleus is a compact sphere that is the most prominent organelle of eukaryotic cells. It is separated from the cell cytoplasm by an external boundary called a nuclear envelope. 中坚力量是eukaryotic细胞最突出的细胞器的紧凑球形。 它从细胞细胞质被分离由称一个核信封的一个外在界限。[translate] ...
Nervous tissue has two main functions: sensing stimuli and sending impulses to different parts of the body as a response. This tissue is what makes up the body’s nervous system, which is split into the central nervous system and the peripheral nervous system. Tissue in the central nervous ...
Blood platelets are made up of cytoplasm, the semi-liquid substance of a cell contained within its cell walls or outer membrane. Platelets are created... Learn more about this topic: Platelets Definition, Function & Normal Range from Chapter 12/ Lesson 12 ...
The cytoplasm is all the material in a cell except for the nucleus. Since water is a major part of a cell, the cytoplasm is made up of about 80% water. The termcytoplasmwas introduced by a Swiss anatomist and psychologist named Rudolf Kolliker in 1863, originally as another name for pro...
How are amino acids made in the cytoplasm? What are proteins made of? What subunits make up proteins? Which characteristic makes the nine essential amino acids essential? What is the monomer of a protein? What sequence determines the consequences of amino acids that make up a protein molecule?
incisive condyloma diagnosis methods, first is takes spot and so on vagina, cervix condyloma structures helps the smear, is handkerchief to dye.In the smear may see two kind of cells, one kind of cell nuclear environment has the corona link, it has usurped the cytoplasma greatly on [...
Once the DNA’s nucleotides have been copied, the mRNA can leave the nucleus of the cell and makes its way to the cytoplasm, where protein synthesis takes place. Here, complicated molecules called ribosomes ‘read’ the sequence of bases on the mRNA molecule. Individual amino acids, which co...
Chromosome 18 in humans is an example of a chromosome with well-known genetic defects associated with specific aberrations in the chromosome. This chromosome is about 78 million base pairs long and makes up 2.4 percent of human DNA. (This makes it smaller than average; based on human chromosome...
What is the benefit of RNA being single-stranded? What if we have a stop codon in the middle of an mRNA sequence? Why do humans need mRNA? mRNA is needed to synthesize what in the cytoplasm? Which molecule carries the instructions for producing mRNA?
What is the nuclear membrane in an animal cell? What organelles are found in white blood cells? What chemical structure makes up the cell membrane? What are the four parts of the cell membrane? What is the function of the cell membrane?
