What type of hormone is displayed below?

Which of the following statements about aminoacyl-tRNA synthetases are TRUE? Multiple answers are possible!

The activation of Insulin by posttranslational modifications proceeds through certain distinct steps. Choose the correct statements and bring the steps into the correct order from beginning to last! Not all statements are needed, you have to read carefully! A) The N-terminal “end segment” is removed by the specific cleavage action of proteases B) This yields the molecule “insulin”. Insulin is made of three polypeptide chains stabilized by four disulfide bonds C) This yields the molecule “insulin”. Insulin is made of two polypeptide chains stabilized by three disulfide bonds D) Insulin is initially translated as a precursor of preproinsulin E) The C-terminal “end segment” is removed by the specific cleavage action of proteases F) The “central segment” is removed by the specific cleavage action of proteases G) The thiol groups of the six cysteine residues in preproinsulin oxidize to form three specific disulfide bonds H) The thiol groups of the eight cysteine residues in preproinsulin oxidize to form four specific disulfide bonds I) This yields the molecule “proinsulin”  

Neurotransmission is the process by which signaling molecules called neurotransmitters are released by the sending neuron and bind to the receptors on the dendrites of the receiving neuron. This process occurs in the synapse over a short distance. Neurotransmission is an example of _____________________ cell signaling.   

What is the difference between endocrine and exocrine glands?

Which of the following immune cells are leukocytes (white blood cells)? Multiple answers are possible!

The lytic cycle (pathway) is one of the two cycles of viral reproduction. Generally, it can be described as a five-stage cycle.  Choose the correct statements and bring the stages into the correct order from beginning to last! Not all statements are needed, you have to read carefully!   1) Maturation: The replicated material assembles into the fully formed virus particle 2) Lysis: The newly formed viruses are released from the infected cell by lysis (which is itself destroyed in the process) to seek out new host cells to infect 3) Penetration: The virus infiltrates the host cell and thereby injects its DNA into the host cell  4) Gene Integration: The virus’ genetic material is inserted into the host’s own genetic material 5) Biosynthesis: The virus DNA/RNA is replicate inside the cell, synthesizing new virus DNA/RNA. Viral genes are transcribed and viral proteins are produced. 6) Attachment: The virus attaches itself to the surface of the host cell in order to inject its DNA into the cell 7) Budding: The virus particle is assembled at the host’s cell membrane. During that process, the viral proteins and genetic material is enclosed by the membrane and are then released from the cell without destroying it in the process.  The newly formed virus seeks out new host cells to infect.
