Question 10

Occurring in the ​ ​   nucleus  ribosome mitochondrion , ​ ​   translation transcription  is the process of making an RNA copy from a DNA template. The molecule then enters the cytoplasm. The process in which the mRNA sequence is converted into a sequence of amino acids is called ​ ​   translation transcription . In the cytoplasm, the ​ ​   nucleus  ribosome mitochondrion  reads the amino acid sequence and assembles the protein.

Question 11 Which of the following statements is true regarding pili and flagella assembly? O Pili and flagella are synthesized in a similar fashion; the proteins are produced internally then added to the base of the growing appendage. O Pili and flagella are synthesized in a similar, complex manner, approximately 20 different proteins are made inside the cell then secreted to extend the tip of the appendage. O Pili grow when protein subunits are added to the base, whereas flagellin proteins are added to the tip of the flagella during growth. O Pili grow when protein subunits are added to the tip, whereas flagellin proteins are added to the base of the flagella during growth.

QUESTION 2 Which of the following is NOT a correct pairing of the RNA type and its job? O A. rRNA - in combination with proteins forms the ribosome that is the organelle that builds proteins O B. CRNA - tells the nucleus which protein is needed in the cytosol OC. TRNA - carries amino acids to the ribosome to use in protein building O D. MRNA - takes the message of which protein to build from the DNA in the nucleus to the ribosome

Section 1- Question 14 The separation of cells and cellular components is accomplished with a centrifuge. A sample of cells is first blended to mechanically break apart some of the cells releasing their contents to form a cell homogenate. The remaining whole cells and cell components are separated based on their sedimentation rate by centrifuging the sample at increasingly high speed. The centrifuge spins at up to several thousand rotations per minute (rpm) forcing material to accumulate as a pellet at the bottom of the tube. The liquid portion is removed and centrifuged again to yield four (4) pellets containing the cells or cell components listed in the diagram. Cell homogenate Patient Patient 1 Patient 2 Patient 3 Low speed Patient 4 Medium speed .. High speed .. - ☐☐☐☐ Pellet 1 Whole cells Nuclei Cytoskeletons The separation of whole cells is required for the diagnosis and treatment of certain disease processes in humans. Four patients each exhibiting unique symptoms are shown in…

QUESTION 10 The human form of Cdk1 phosphorylates a protein called Abl, which is a kinase itself. Abl is involved in advancing the cell cycle, but it is unclear how.
