tRNAs move through the ribosome during the course of protein synthesis. A
tunnel runs through the ribosome, right at the interface between the two
subunits, and the tRNAs enter one side of this tunnel and are propelled along
it during each step of protein

1) How do we know that this is the genome of a male?
The 23rd chromosome is an XY chromosome. If this was a female genome then
the 23rd chromosome would be XX.
2) What organism was the first organism to have its genome sequence

Introduction to Cellular Respiration Assignment (65 pts.)
1. Define: biological pathway
Biological pathways are molecules working together within cells.
2. What two things do biological pathways promote within cells? (4 points)
Biological pathways promote

Simple cells, like those found in algae, may only have one or two chloroplasts. More
complex plant cells, however, may contain hundreds. Chloroplasts will sometimes move
around within the cell in order to position themselves to where they can best absorb
The location of ribosomes depends on where a specific protein needs to be made. A ribosome can be
included outside of a cellular membrane in order to make a specific protein (such as producing a
membrane protein). Likewise, ribosomes can be accompanied in
