Total questions: 21
Worksheet time: 50mins
What takes place in the S phase?
H bonds break and 2 identical double-stranded DNA are synthesized
H bonds break and a new DNA molecule is made
The cell divides into 2 identical daughter cells
Mitosis is occuring
DNA replication occurs during the S phase so that
2 identical daughter cells can be produced in the M-phase
DNA can transfer from the mitochondria to the golgi body
4 different daughter cells can be produced in the G2 phase
bioengineered cells can grow and produce a completely new strand of DNA
This image shows
DNA replication
Cell division
Bioengineered molecules
DNA energy transfusion
During cytokinesis
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
Cell membrane pinches to make 2 new identical daughter cells
Each DNA gets pull to the opposite sides of the cell
2 new nuclei form
DNA replicates, cell grows, cell prepares for mitosis and grows a bit more, cell divides
cell grows, cell prepares for mitosis and grows a bit more, DNA replicates, cell divides
cell grows, DNA replicates, cell prepares for mitosis and grows a bit more, cell divides
DNA replicates, cell prepares for mitosis and grows a bit more, cell grows, cell divides
Daughter cells created by mitosis have
half of the parents genetic material
twice the parent cell's genetic material
an exact copy of the parent cell
have a brand new DNA structure
Idenificy the correct order of DNA Replication:
DNA is separated, free nucleiotides are added, identical DNA is synthesized, DNA unwinds
DNA unwinds, DNA is Separated, free nucleiotides are added, identical DNA is synthesized
identical DNA is synthesized, DNA unwinds, DNA is separated, free nucleiotides are added
DNA unwinds, free nucleiotides are added, identical DNA is synthesized, DNA is separated
Enzymes play an important role in DNA Replication by:
Speeding up the process and helping through various stages
Slowing the process down by lowering the activation energy
DIvides the cells into 2 daughter cells
Works to build the double helix shape when the chromosomes line up
When cells go through mitosis repeatedly without entering interphase, this results
arthritis
cancer
mutation
diabetes
What is cancer?
The cell cycle getting stuck in G1 phase.
The inability for a cell to complete the cell cycle.
The uncontrolled division of cells.
A cell getting stuck in metaphase.
Which of the following best describes stem cells?
Cells that have already differentiated
Cells that cannot undergo cell division
Cells that have been mutated
Original human cells that are able to develop into specialized cells
Specialized cells such as muscle, blood, or nerve cells are caused by cell differentiation led by
Environmental Factors
nucleus
ribosomes
plasma membrane
Cells differentiate to perform different functions because
all genes are turned on inside that cell
all genes are turned off inside that cell
different genes are turned on inside that cell
different genes are turned on or off inside that cell
During the process of differentiation
all sections of DNA are activated to determine the structure of a body cell
ONLY ONE section of DNA are deactivated to determine the structure of a body cell
only specific sections of DNA sequence are activated to determine the structure and functions of a body cell
Unspecialized cells in our body that has the ability to differentiate into different types of cells are called
specialized cells
differentiated cells
nerve cells
stem cells
