• I know what genes are and I can explain what they do. 

• DNA
• GENES
• CHROMOSOMES
• CHROMATIDS
• NUCLEOTIDES
• HAPLOID
• DIPLOID

• I know what the different types of cell division are and what the main differences are.
• I understand the terms replication, translation & transcription and I can explain in detail in what order they happen and what the differences are. 
• 
  

• REPLICATION
• TRANSLATION
• TRANSCRIPTION
• MEIOSIS

• m-RNA

Practice assignments in class: #1

Look at the image included in this slide, one is mitosis and the other is meiosis. 

A. Which one is which?

B. Please explain your answer in detail. (use key words like chromosomes, gametes, body cells, haploid and diploid)

Practice assignments in class: #1

A. The left is meiosis and the right is mitosis.

B. With mitosis the body copies the cells and chromosomes to produce new diploid body cells. With meiosis  the body splits the chromosomes one extra time to produce  haploid gametes. 

Practice assignments in class: #2

When making mRNA, the nucleotide Thymine gets replaced with the nucleotide Uracil (U). 

A. During which process does your body make mRNA

B. Look at the picture below of a piece of DNA, write down in your notebook what you predict the piece of mRNA will look like.

Practice assignments in class: #2

A. During the process called transcription.

B. A-U-U-G-A-C-G-U-C-C-A

Practice assignments in class: #3

Practice assignments in class: #3

A. Heterozygous means two different genes which the fly has the genotype "Ww".

B. Possible genotypes for the gametes are "W" and "w".

C. 

	W	w
W	WW	Ww
W	WW	Ww
