This stage scans the mRNA and has the start code A-U-G, builds proteins.
Then Elongation. tRNA is shuttled over while mRNA is being scanned. Also, Polypeptide chain builds up to form proteins.
Last Termination, this ends the process.  ]]> 2021-02-18 22:29:33 UTC https://padlet.com/201009838/Bookmarks/wish/1217285441 Phases/March 9 201009838 https://padlet.com/201009838/Bookmarks/wish/1266409616 Module Drawing and the day went well we learned about the different phases like G1,S,G2, and M.

1. DNA is made up of Nucleotides which have 4 different bases.
2. The DNA replication process is semiconservative.
3. The complementary vases are made up of DNA bonds.
Two Sentences
1. The DNA replication process involves splitting a DNA strand into two and creating a new complementary strand to connect.
2. DNA is the building block of life which is shaped through the different DNA base sequence.

I don't have any questions that you didn't answer in class. ]]> 2021-03-05 22:57:38 UTC https://padlet.com/201009838/Bookmarks/wish/1275824867 March 11 201009838 https://padlet.com/201009838/Bookmarks/wish/1275847682 Today was a big review and ketchup day, didn't do any new assignments just new ones.  We watched a video about mitosis. Mitosis plays an important role in Cell replacement, development and growth, and asexual reproduction]]> 2021-03-05 23:13:31 UTC https://padlet.com/201009838/Bookmarks/wish/1275847682 March 13 201009838 https://padlet.com/201009838/Bookmarks/wish/1290383776 I learned that prophase is the first stage of mitosis and one question I have about what we learned today was how the cells divide. Transcriptions are found in the 2nucleus. Went really well and learned a lot about duplicating DNA]]> 2021-03-09 23:58:15 UTC https://padlet.com/201009838/Bookmarks/wish/1290383776 March 15 201009838 https://padlet.com/201009838/Bookmarks/wish/1313021722 We just talked about upcoming assignments like the new lab and essay. I still have a question though, when is the due date for the lab and essay? ]]> 2021-03-15 22:28:37 UTC https://padlet.com/201009838/Bookmarks/wish/1313021722 March 17 201009838 https://padlet.com/201009838/Bookmarks/wish/1333408685 Today's class we had to make a model of all stages of mitosis and the teacher explained the new lab that we have to start on our model of mitosis. ]]> 2021-03-21 02:32:23 UTC https://padlet.com/201009838/Bookmarks/wish/1333408685 March 19 Self Assessments 201009838 https://padlet.com/201009838/Bookmarks/wish/1333415788 3 Facts 
1. There are six stages of mitosis, Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.
2. Mitosis produces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells. 
3. During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
Two sentences
1. During interphase, the cell grows and the nuclear DNA is duplicated.
2. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes.
Questions
1. How come sometimes online it says telophase is the last phase of mitosis?]]> 2021-03-21 02:41:58 UTC https://padlet.com/201009838/Bookmarks/wish/1333415788 March 31 201009838 https://padlet.com/201009838/Bookmarks/wish/1373467218 We looked at some people's labs and it was a overall fun day.]]> 2021-03-31 21:23:05 UTC https://padlet.com/201009838/Bookmarks/wish/1373467218 March 29 201009838 https://padlet.com/201009838/Bookmarks/wish/1373468430 Worked on my essay on tumors all day, again.]]> 2021-03-31 21:23:44 UTC https://padlet.com/201009838/Bookmarks/wish/1373468430 March 25 201009838 https://padlet.com/201009838/Bookmarks/wish/1373469571 Worked on my essay on tumors all day.]]> 2021-03-31 21:24:19 UTC https://padlet.com/201009838/Bookmarks/wish/1373469571 April 20 201009838 https://padlet.com/201009838/Bookmarks/wish/1440070792 Haploid vs Diploid
Mitosis vs Meiosis
Mitosis 
Mitosis produces diploid cells, Mitosis takes place all over the body, Made to assist the body in cellular restoration (healing), The genetics are a one for one copy of the parent cell.
Meiosis
Meiosis only occurs in sexual organs and produces sex cells, Produces 4 haploids gametes, Made to procreate new life cells (Make children), Crossover only occurs during Meiosis.]]> 2021-04-20 21:29:37 UTC https://padlet.com/201009838/Bookmarks/wish/1440070792 April 22 201009838 https://padlet.com/201009838/Bookmarks/wish/1457985076 Identical twins come from the same egg so they start out exactly the same and fraternal twins come from when you have 2 eggs that get fertilized at the same time by 2 sperm]]> 2021-04-26 05:50:30 UTC https://padlet.com/201009838/Bookmarks/wish/1457985076 April 16 201009838 https://padlet.com/201009838/Bookmarks/wish/1457986973 Sex cells have 23 chromosomes 
  • Meiosis has two stages
  • The steps are the same as mitosis
  • two and fraternal twins happen when two eggs become fertile at the same time

•I learned that the phases of Meiosis is like Mitosis
•I learned that Meiosis is for Sexual Reproduction
