Answer:
Answer: C. The offspring are genetically distinct from the parents because they are produced by sexual reproduction. Explanation: Sexual reproduction occurs through the fusion between an egg and a sperm cell
Answer:
PCR is used in many research labs, and it also has practical applications in forensics, genetic testing, and diagnostics. For instance, PCR is used to amplify genes associated with genetic disorders from the DNA of patients (or from fetal DNA, in the case of prenatal testing).
Answer:
Pink Striped flowers
Explanation:
Incomplete traits result in a "mixing" of 2 traits. So with a Rr individual, there will be pink striped flowers.
Receptor proteins are molecules inside a cell or on its surface on which ligands bind. A ligand is any substance (e.g. a hormone, drug, functional group) that binds specifically and reversibly to another chemical entity to form a large complex.
Receptor proteins found inside a cell are called internal receptors or intracellular receptors or cytoplasmic receptors.
They act as regulators of mRNA synthesis to mediate gene expression.
When a ligand binds to an internal receptor, the receptor changes in conformation and exposes on itself a site that can bind to DNA.
The receptor joined to the ligand moves into the nucleus where it binds to a specific site on the cell DNA. Once bound, it promotes the process of transcription where information is copied from DNA to mRNA
Answer:
The level of specialization is given by the function.
The function of the organ makes the cell as it becomes mature, its more specific function becomes.
First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.
After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.
Explanation:
The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.
