Concept explainers
To describe:
One way in which endocrine, autocrine and contact-dependent signaling pathways are similar to one another and one way in which they are different from one another.
Concept Introduction:
Endocrine signaling involves the release of the hormone from the cell. This hormone is transported in the blood. It reaches the receptor and binds to it and activates the cell signaling response.
Autocrine signaling involves the release of the chemicals from the cell and involves the binding of these chemicals on the same receptor. Paracrine signaling involves the communication between the cells when the chemical released by one cell binds to the receptors present in the neighboring cell. The circulation of the hormones in the circulatory system is less.
Contact-dependent signaling involves the communication among the cells due to the formation of gap junctions in between the cells.

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
