RNA and DNA Tuesday

Agenda:

1. We checked in our Double Bubble maps
2. We discussed our Maps
3. Talked about the different types of RNA
4. Went to Math lab to log into our online book

The double bubble map was between the DNA and RNA . DNA and RNA are similar in the following ways: They both have long chains of Nucleotides, form using a replication fork, made up of nucleotides, sugar, nitrogen base, and phosphate, form using enzymes, are nucleic acid, and have Cytosine, Adenine, and Guanine. Things that are DNA only are the sugar is Deoxyribose, has Thymine, Double stranded, stays in the Nucleus, contains the code for protein, and uses DNA polymerase as the enzyme to form. Things specific to RNA are the sugar is ribose, is single stranded, has Uracil instead of Thymine, is found in the nucleus and cytoplasm, plays a major role in protein synthesis, and has three type of it Messenger RNA (mRNA), Transfer RNA (tRNA), and Ribosomal RNA (rRNA).

After we went over the Double bubble map we talked about the different type of RNA: rRNA, mRNA, and tRNA.

• rRNA (Ribosomal RNA) makes up most of ribosomes and carries instructions for making Ribosomes. rRNA is found in the Nucleolus and finally Ribosomes are very special because they are found in primitive cells so it is believed that they are one of the oldest organelles and are prehistoric.
• mRNA (Messenger RNA) carries the DNA information from the DNA in the Nucleus to the ribosome and has the amino acids put on it to form a polypeptide.
• tRNA (Transfer RNA) carries the amino acids one by one to the ribosome where it is put on the mRNA mixing it with the step before to make a polypeptide

Some other information Mrs. Stein gave us to better understand this is: an amino acid are the building blocks of protein when you link amino acids together you get a polypeptide. A polypeptide is a group of amino acids linked together. A polypeptide can also be called a baby protein because when it matures it forms Protein.

Homework:

1. Flow map on protein synthesis due Tomorrow hint: Starts which RNA synthesis on 13.1 and goes into 13.2 highly recommended you go to the online book and watch the animations and play the game
2. Test and Paper due November 23

The next scribe is David
