Biology A Final Exam Review

Organelle that reads codes and build proteins

• Endoplasmic Reticulum

• Nucleus

• Cell Membrane

• Ribosome

How do CELLS communicate?

• Cells do not have to communicate with each other, they all work independently

• Cells communicate using a Chemical / Hormonal Signal.

• Cells communicate within the cell only

Which is an example of the BASE PAIRING RULE

• CGTACGGT

  GCATGCCA

• ATTAGCAT

  ATTAGCAT

• AUGAUAU

  UACUAAU

• none of these appear to be correct

Why is DNA considered semi conservative?

• Upon replication, an old strand binds with an old strand.

• Upon replication, an old strand binds with a new strand

• Upon replication, an new strand binds with a new strand.

• DNA never replicates.

Protein synthesis has 2 main steps…where do they take place?

• Transcription takes place in the cytoplasm, and translation takes place in the nucleus

• Transcription takes place in the nucleus, and translation takes place in the cytoplasm

• Transcription and translation both take place in the nucleus

• Transcription and translation both take place in the cytoplasm

You go outside on a cold winter day. As your temperature drops your body begins to shiver. This response is one way your body tries to maintain

• Homeostasis - negative feedback

• Homeostasis - positive feedback

• Synthesis - of glucose

• Bodies do not respond to external stimuli

This is an example of

• Positive feedback

• Negative feedback

• No feedback

A protein is a chain of

• Lipids

• Glucose

• Amino Acids

• Bases

Negative feedback starts when the body detects

• An effect

• A response

• A control center

• A stimulus
