When taking your blood pressure, you are most directly measuring:

A student measured her blood pressure and found it to be 110/72.  The #72 describes:  

Protein Synthesis Order: Use the letters below to put the events of protein synthesis in the correct sequence. Each letter is used only once: A. tRNA molecules bring appropriate amino acids to the ribosome  (codons/anticodons need to be complementary) B. mRNA attaches to ribosome in the cytoplasm to be translated C. amino acids join by dehydration synthesis and fold into a functional protein D. DNA Template strand is copied into mRNA transcript in the nucleus First step of protein synthesis [step1] Second step of protein synthesis [step2] Third step of protein synthesis [step3] Last step of protein synthesis [step4]  

Which of these is an example of a somatic cell?

B-cell Activation Fill in the blank. (Read this paragraph through like you are explaining how B-cell activation could  work) Use the words in the table below to fill in the appropriate blank.  Answers must be spelled correctly – so you can copy and paste from the chart. phagocytes lymphocytes plasma cytotoxic antigen memory antibodies perforin histamines APC’s   B-cells can get activated when they encounter a particular foreign [blank1] which match the receptors on the B-cell’s surface.  The activated B-cell then divides into [blank2] cells which will be used if there is ever a second exposure and [blank3] cells which produce [blank4] that will be used to tag the foreign antigens. Once tagged the foreign antigen/pathogen will be destroyed by [blank5].      (When done – read through the sentences with your answers to see if it makes sense)

The portions of genes that can leave (or exit) the nucleus to be translated/expressed at the ribosome are called ________.
