Cell Cycle 1
The longest phase of the cell cycle is?
Interphase
In this phase of mitosis, spindle fibers pull chromosomes to opposite poles of the cell
anaphase
What is the role of a spindle in mitosis?
It helps break down the chromosomes
What types of RNA are involved in protein synthesis?
rRNA, mRNA and tRNA
Amino Acid
the building blocks of proteins to make up proteins primary structure
In what stage of the cell cycle does division occur?
Mitosis or specifically cytokenesis.
Telephase also exepted.
Chromosomes are aligned across the middle of the cell
metaphase
2 daughter cells
What does mRNA do?
Sends a message of genetic instructions to assemble proteins to encode a specific amino acid
What is the template to make RNA?
DNA
The series of events that a cell goes through as they grow and divide is called the _______ ______.
Cell Cycle
How is cellular division (mitosis) important for how organisms grow bigger?
Organisms grow bigger as their cells divide. Each time their cells divide, the organism grows bigger.
Every baby is made of fewer cells than an adult. As babies grow bigger, their cells divide to make a bigger organism.
A parent cell having 4 chromosomes will produce 2 daughter cells containing
4 chromosomes
What does RNA do?
MAKES PROTEIN!
What is the use of a codon chart?
To use the ... to translate the message of the code
What are the 4 phases of mitosis in order?
Prophase Metaphase Anaphase Telophase
Spindle fibers shorten and begin to pull chromosomes apart
anaphase
Cancer can't control a cells
growth rate
What does tRNA do?
tranfers a particular amino acid to a growing polypeptide chain
Why does a peptide chain ocassionally stop?
to create a certain genetic code
Results in two identical daughter cells and occurs at the same time as telophase
Cytokinesis
This is the fourth and final stage of mitosis where the cells are being pinched apart
Telophase
RNA contains the sugar
Ribose
Codon
sequence of 3 nucleotides on a mRNA molecule that encode a specific amino acid
Polypeptide chain
long chain of amino acids that are created during translation
