Answers
1
an organism needs what new cells?
skin
all of above!
bones
white blood cells
2
Gene expression takes place in the brain.
False
True
3
gene expression and gene regulation related
True
False
4
How is gene expression related to protein synthesis?
produce a protein through a process called translation.
They are siblings
Trick question, They aren't.
The RNA is then used as a template to-
5
What tells the stem cell what type of specialized cell it will be?
Older cells.
(Transcription factors) RNA
Their mother and father.
stem cells
6
As cells grow in an embryo, they differentiate, becoming a distinct type of cell.
True
False
7
How do gene expression and gene regulation differ?
Gene expression is the process that converts the genetic information.
gene expression is the main process GR is an essential controlling part.
They don't.
Because they do.
8
Why would an organism need new cells like skin?
To pass biology class.
a cell grows, prepares to divide, and then divides into two daughter cells.
To live.
epithelial cells are differentiated to control absorption and secretion.
9
Differentiated cells perform different functions.
True
False
10
How is gene regulation related to cell differentiation, or specialization?
They are so special!
Generic embryonic cells differentiate into specialized cells.
This happens as a result of a process known as gene expression.
Gene expression refers to the set of genes that are switched on or off.
11
What are stem cells?
nonrenewable cells that can not devlop AT ALL.
plant cells.
renewable cells that can devlop into many cells.
cells that do not help growth.
12
Gene regulation is the process used to control the timing, location and amount in which genes are expressed.
False
True
13
which one allows each type of cell to perform its necessary function.
Cell differentiation
Cell diferantiation
stem cells
specialized cell
14
Where are stem cells found in animal systems?
Liver & skin
All of above
bone marrow
Brain
15
What are the internal & external cues for stem cells?
adult stem cells
Pluripotent and adult stem cells
Pluripotent
cell stems
16
What is cell differentiation?
the template DNA strand reading TGATC paired with the nucleotides ACTAG.
It's a circle.
Stem cells made of bones.
Allows each type of cell to perform its necessary function.
17
Transcription is a process in which a complementary strand of RNA is formed from the section of DNA that contains a gene
False
True
18
cells have the same structure and function.
False
True
19
gene regulation is related to cell differentiation.
False
True
20
Do all cells have the same structure and function?
Yes, They do.
Simply no.
Cells with different functions generally have different shapes.
cells even within the same organism, may have their own unique structures.
