The Importance of Proteins
What is the shape of DNA?
double-helix
True or False: Mitosis and Meiosis are the same process
False!
When is the last day of school?
True or False: mutations are uncommon.
False! Mutations are relatively common
A sequence of three nucleotides on a mRNA molecule that encodes for a specific amino acid
Codon
True or False: multiple codons encode for the same amino acid
True!
What is a special kind of cell division where gametes (4 daughter cells) are formed?
Meiosis!
When is the start of April Spring Break? (not including the weekend leading up)
Monday, April 15th! YAYY!!
What are permanent changes to an individual's DNA?
Mutations
A physical or behavioral characteristic of an organism
What is a specific pattern of nucleotides that produces a specific protein which in turn codes for traits?
Gene
True or False: Cells divide twice in mitosis
False! Cells divide twice in meiosis
How many more IOWA testing days are there remaining?
Three! (Monday, Tuesday, and Wednesday)
What enzyme is needed for lactose tolerance?
Lactase
A threadlike structure of DNA and protein; found in the nucleus of eukaryotic cells
Chromosome
What is the building block of protein?
Amino Acids
What are the steps to mitosis?
Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
True or False: Miss Somaiy is not lactose intolerant
False! She IS afflicted by lactose intolerance :(
Explain sickle cell disease
Sickle cell disease causes blood cells to become sticky, rigid and shaped like a crescent moon. These have trouble moving through blood vessels, which can block blood flow and oxygen from other parts of the body
The creation of a new individual from combined genetic information of two parents of two different sexes.
(Sexual) Reproduction
What is the shape of RNA?
Single-strand of nucleotides
In what phase of Meiosis does crossing-over (genetic recombination) occur?
Prophase I
What will be Miss Somaiy's new last name?
Pacchioli! (not pepperoni)
Explain the mechanism of lactose intolerance from babies to adulthood.
Babies are born able to digest milk. Somehow, the genes that produce lactase shut off as people become adults, which means they cannot digest lactose.
Reproduction that only requires one parent (for example, binary fission, budding, and fragmentation)
Asexual Reproduction
