Review of transcription and translation

After I have given you the answer, be sure to write down the answers of the questions for yourself!

00:18

Is all genetic material present in the nucleus?

00:18

Why is the genome stored in the nucleus?

00:24

How many chromosomes?

00:32

Do they always look like this, the chromosomes?

00:41

What is it exactly that we see here?
Is it all the same size?

00:52

Where does RNA polymerase exactly attach? How is this called?

00:59

What is the name of the single strand of DNA where the mRNA is being made on? And what is the name of the complementary strand?

01:00

1. What is the direction of the mRNA synthesis?
2. What is the direction of the DNA strand that is being read?
3. Is the direction of transcription the same as the direction of replication?

01:06

What is the codon where the mRNA starts to be synthesized?

01:26

Removing and adding sections of RNA. What is going on here?

01:27

01:46

What are ribosomes made of?

02:04

If there are 20 amino acids and 4 basepairs. How many different codons are there?
How does this work?

02:08

What is the first codon of the mRNA that is being read?
What is the first amino acid that is connected to the tRNA?
What is the codon of this tRNA?

02:18

What are the bonds that are being formed between the amino acids?
How do we also call the molecule that is being formed?

02:21

What are the three sites in the ribosome complex where the tRNA attaches?

02:35

What are the different levels of protein structure and what are the characteristics of each level?

Do you have any questions for me?

If you want to know something or don't understand something, 

ASK NOW!

Make a set of criteria and evaluate your neighbor!

To evaluate the homework (drawing) of your neighbor/ friend!

First set up the criteria. What concepts need to be there? Directions? Involved steps? Proteins? Other molecules?

Then evaluate and give feedback to your neighbor! 

What is good? What could be done better?

Homework

Make summary of pages 388-391!

Write down important steps concepts and names of molecules/ DNA fragments!

Write down what they do/ what is their function?
