2. There once was a chicken
who looked a little
different than everyone
else.
3. All his friends could waddle
around with their tails in
the air, but he couldn't. He
didn't have one.
4. All of his siblings had tufts
of fur that grew beneath
their ears and he didn't.
5. Everyone else in the
chicken coop played Simon
Says. But he didn't.
6. He wandered alone picking
up fallen out feathers
hoping to attach them to
himself so he too could
have ear tufts and a
tail.
7. "Maybe," he thought, "Just
maybe if I have them too,
then all the other chicks
will like me, and I can play
their games too.”
8. One day he asked his dad,
“Dad? Why do I look different
than everyone else? All of my
friends and all of my brothers
have ear tufts and tails. I am
rumpless. Is something wrong
with me? ”
9. “At school, I learned that
when you grow your cells
multiply by meiosis,
sometimes something goes
wrong and you can be
different. Am I mutated? I
think there's something wrong
in my DNA."
10. Dad: “Nothing's wrong with
your DNA. You see, we are all
the same because we are all
made up of ACG&T but our
sequences aren't the same, so
we all look different.”
12. Dad: “The sequence is the
order of the codons. The
order is what makes you have
the traits you do.”
13. Chick: “Well why did my
codons get all lined up so I
have no tail and no tufts?”
14. Dad: “The reason you have
the traits you do is because I
gave you 23 of my
chromosomes.”
15. Chick: “If i got 23
chromosomes from you, dad,
where did I get the rest?
Surely I am not only made up
of 23 chromosomes.. And I
don't even look like you."
16. Dad: “You're right, you also
got 23 chromosomes from
your mom.”
Chick: “Is this why I don't
have a tail or tufts like my
brothers and sisters?”
17. Dad: “That's right. Clearly, I
have the dominant gene for a
tail, and I must be
heterozygous because you,
my son, don't have a tail, and
neither did your mother.”
18. Chick: “My mom was
araucana too?”
Dad: “That's right. She and I
are both aracuana.”
20. Analysis
During the growth process of cells, they reproduce through
mitosis. This process occurs daily, and even many times a day as
cells continually need to be replenished as others die.
As cells form more complex organisms, they produce different
types of cells that result in a functioning organism. A group of cells
of the same type form a larger structure called a tissue (skin,
muscle). Multiple tissues can form an organ (eye, kidney). This
variation among cell groups is known as differentiation. When cells
become a part of a tissue or organ, they lose their ability to work
alone and cannot survive without the support of other cells. Thus
we see that cell differentiation is essential for a working body.
21. Analysis
The portions of DNA that carry genetic information are
called genes. Genes contain a specific sequence of
nucleotides that contain the instructions for a certain
protein. In the story which showed what we predicted that
the mother was aracuana because of the genes it inherited.
The proteins determine which physical characteristics an
organism displays. All organisms are the same in that they
are all made up of AGCT but it is the sequence that makes
them different. Meiosis is important in sexual reproduction
because it reduces chromosome number from diploid to
haploid.
