Levels of Organization
Multiple types of tissues working together.
Organ
What is the genetic code for all life on Earth?
DNA
What needs to happen to the DNA before mitosis?
It needs to replicate.
What is the definition of a gene?
A segment of a DNA molecule that contains the instructions for producing a trait in an organism
The smallest level of organization in BIOLOGY?
The cell.
What molecule carries the message from the genetic code (i.e. the "messenger")?
RNA (mRNA)
You see a cell with the chromosomes lined up down the middle; what phase of mitosis is this cell in?
Metaphase.
What would the code for the complementary strand of DNA look like, based on this code?:
ATGCGATTCGGATTA
TACGCTAAGCCTAAT
What is the definition of tissue?
Multiple, SIMILAR cells coming together for a specialized function.
What is the process of changing from DNA to RNA called?
Transcription.
In a cell, you see that the nuclear membrane is present, but it's starting to dissolve. What phase of mitosis is this cell in?
Prophase.
What is a mutation? Why are mutations important?
A mutation is a change in DNA, and they are important because they can ultimately affect proteins.
If multiple kinds of tissues aren't properly working together in the body, what level of organization is failing?
Organ failure.
What is the process of changing RNA to proteins called?
Translation
What is the result of mitosis?
2 identical daughter cells from 1 parent cell.
In ducks, blue feathers are dominant to green feathers. A female duck has green feathers and mates with a male who has blue feathers, but whose father had green feathers. What is the probability they will have offspring with green feathers?
50%
What level of organization is the SKIN classified under?
Organ

What are the steps of mitosis, in order?
Prophase, Metaphase, Anaphase, and Telophase.
What is DNA like when compared to baking?
