Genetic Variety

Genetic variety has to do with our Reebops because all of our bugs don't look exactly alike. They all may have similarities, but none are exactly alike, just like humans aren't exactly alike. Reebop's are different because of genetic variety. For example, my P1 bug has a green and brown body while my F1 bug has only green. Another example is that my F1 bug has curved feathered anntenaes and my F2 bug has curved anntenaes with no feathers on them. Genetic variety happens because the bug that mated with the P1 generation, or any other generation, might have had some other traits that the zygote will inherit.

From this picture you can see that the F2 generation is a variety of green and yellow pease because the P generation had a green pea, so the genetics can be passed along of having a green pea.

1. If I could go back in time I would tell myself about selective breedingl. I would tell myself that you can only do selected breeding with animals that have almost the same amount of chromosomes. I would tell myself this because I think that it would've helped me understand the concept of selective breeding a lot easier.

2. I think to help with this concept we could try to breed different types of small animals with different amounts of chromosomes and then we can also breed animals with about the same amount of chromosomes. We could do that because it would explain that you can only breed two different species with the same chromosomes. An example we came up with is a liger is a mixture of a lion and tiger because they have about the same amount of chromosomes. If we tried to breed a lion and dog it wouldnt work because they dont have the same amount of chromosomes.

3.

If you look at the dog chromosomes and the cat chromosomes you can tell that they cannot breed because the dog has 78 chromosomes and the cat only has 38.

1. If I could go back and tell myself something about the differences between mitosis and meosis I would say that mitosis makes a diploid cell and meosis makes haploid cells. I think this would help me in the furture because if I see a diploid cell, I can determine that it went through mitosis. For example, if a saw a skin cell I would know that it went through mitosis because it is a diploid cell. If I saw a sperm cell, I can tell that it went through meosis because it is a haploid cell.







2. I think if we did an experiment where we looked at a lot of different cells and determined if they went through meosis or mitosis, it would be helpful. I think this would be helpful because it will help us see the differences of the diploid cells and haploid cells, and mitosis and meosis.

1. What science ideas did you learn?

This week we started learning about meosis. I learned that the steps of meosis are prophase I, metaphase I, anaohase I, telophase I, prophase II, metaphase II, anaphase II, telophase II, and gamete. I learned that mitosis and meosis are similar in someways and they are also different.

2. How did you learn these ideas?

I learned these ideas by watching simulations on the computer. After that we read about what that phase did and then we wrote it down in our own words. I also made a venn diagram showing how meosis is similar to mitosis.

3. How will these ideas help you?

These ideas will help me because in the future when I look under a microscope, I will be able to determine if the cell is preforming meosis or mitosis. This will help me because I can use that information to make better conclusions and hypothesies.

1.What science ideas did you learn?

This week we learned more about mitosis. We did a lot of different activities to help us learn. We calculated that a cell spends most of it's time in interphase which is where it just respirates and does other normal things.

2.How did you learn these ideas?

I learned these ideas by doing online simulations about mitosis. I think the online simulations really helped me understand mitosis better because they actually showed what was going on. We also had a lot of class disscusions on mitosis and what each stage did. Finally, we did different worksheets that we had to answer questions about mitosis.

3. How might these ideas be helpful?

These ideas will be helpful because now when we are looking under a microscope, we can identify what stage each cell is in. This would be helpful because it would help us with our hypothesis and predictions in the future.

1. This week we learned about the process of protien synthesis. We also learned about the organelles again. We all made analogies comparing a cell and something that we thought was like a cell in some sort of way. I learned that the process of protien synthesis goes like this..
First the DNA gets a message. The mRNA then gives that message to the rbosomes. The ribosomes solve that message and tell the amino acids what they have to do. They DNA unzips and the amino acids match up with a base. Three bases put together form a codon. Finally, the codon makes RNA.

2. I learned about the process of protein synthesis by playing this game in class. Different students acted as different organelles and we acted out the process of protiensynthesis. I think participating in this game really helped me learn about proteinsynthesis. I learned about the organelles by making an analogy. I think that this helped me learn about them because I really had to think about the organelles and their functions to make a correct analogy.

3. This is important to know because it will really help me be more prepared for the test on Monday. It is also important to know about these things because they will help me in future scientific investigations because i will be able to identify protiensynthesis and also identify the different types of organelles.

First, a message is sent to the cell to see how much protien it needs to make. The DNA starts to come undone so there is only a gene that has to do with that protien. The nucleotides match up with on sugar backbone to make mRNA. A matches up with U and C matches up with G. Many copies of RNA are made and they leave the nucleus and enter the cytoplasm. The RNA comes together with a ribosome and the ribosome reads the message that the RNA had. There are codons and they have to be read. When that is finished the right amino acids are activated by an enzyme. Then the amino acids attaches to the correct tRNA, or a transfer RNA. Then that tRNA goes and conects to the next one and so on! That happens until everything is read and it forms a polypeptide chain. The polypeptide folds as it's final transformation. Multiple copies of protien are made in this process. The mRNA is recycled so it can be used in different transformations.
