In Section 21.10 we briefly discussed the Human Proteome Map (HPM). An interactive Web site for the HPM is available at http://www.humanproteomemap.org. Visit this site, and then answer the questions in parts (a) and (b) and complete part (c). How many fetal tissues were analyzed?

Hi, everyone. Let's look at our next question. It says based on the information available on the website www dot human proteome AP dot org, how many adult human tissues were used in the human proteome AP H P M? So let's take a minute to go to this website and look up right on the front page. There's information about how they compiled this map. So you can pause the video and look there. So let's recall what is what is a protium. So a proteome is the entire complement of proteins that can be expressed in an organism. So once the human genome project was complete, the proteome map was sort of the next step looking for what are the actual proteins. And of course, there are many, many, many more proteins that are expressed and there are genes due to alternative splicing, allowing many more proteins to be produced than there are genes in the genome. So because genes are expressed in different ways in different tissues and especially during development, as cells differentiate, um you have to look at a lot of different tissues and different stages of development. So our question asked how many adult human tissues were used. And when you look it up on that page, on the website, we see that there were 17 adult tissues, nine primary Hematopoietic hematopoietic cells and seven fetal tissues that were used as part of this map. So our answer here will be choice. C 17 adult tissues used in creating this map. See you in the next video.
