What is the name given to the process in which a cell divides into two new daughter cells? The stages of embryo development from the zygote stage till the germ layers are formed. What do the germ layers become? What stage of the life cycle produces the gametes? What stage of the life ...
Which of the following is the part of the brain which produces emotions? A) Thalamus B) Hypothalamus C) Limbic system D) Pineal gland The Brain The brain is the most amazing and complicated organ of the body. It has been divide...
"Many citrus types display nucellar embryony, which is a process by which somatic cells of the nucellus (the tissue in the ovule but out- side the embryo sac) produce multiple embryos that are genetically identical to the maternal parent plant. Nucellar embryony poses a major impediment to ...
Mitosis is considered an “equational” form of cell division — it occurs in cells that do not produce gametes (e.g., somatic cells). During mitosis, a cell divides once to produce two daughter cells with genetic material identical to that of the original parent cell and to each other. ...

It also includes transfection procedures into fetal bovine somatic cells, generally fibroblasts, and the nuclear transfer into enucleated bovine oocytes, generating thus transgenic embryos. The method also includes other procedures to generate transgenic embryos for the further expansion of the transgenic ...
A myriad of gene induction events underlie nerve growth factor (NGF)-induced differentiation of PC12 cells. To dissect the signal transduction pathways which lead to NGF actions, we have assessed the relative roles of NGF receptor, Src, ... G D'Arcangelo,S Halegoua - 《Mol.cell.biol》 被...
Meiosis is atype of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies ...
In the brain,hormones alter the production of gene products that participate in synaptic neurotransmissionas well as affect the structure of brain cells. As a result, the circuitry of the brain and its capacity for neurotransmission are changed over a course of hours to days. ...
Protein synthesis is the process that makes new proteins for the cell. Protein synthesis has two main steps: transcription and translation. During transcription, mRNA is created and during translation, the actual proteins are made.Answer and Explanation: ...
