Science Cell Test

Question 1

Nucleus

Answer 1

regulates synthesis of proteins in the cytoplasm though use of messenger RNA.
Messenger RNS is a transcribed segment of DNA that is used as a template for protein making. Produced in Nucleus

Question 2

DNA

Answer 2

: DNA produces RNA

Question 3

RNA

Answer 3

RNA produces protein for the cell

Question 4

Ribosomes

Answer 4

Responsible for the synthesis of proteins in cells. It serves to convert the instructions in messenger RNA into the chains of amino-acids that make up proteins

Question 5

Rough Endoplasmic Reticulum

Answer 5

Holds ribosomes while it is making protein

Question 6

Vesicle

Answer 6

Transport the proteins from the ribosomes to the golgi apparatus where they are stored into new vesicles. The vesicles migrate to the membrane and release their protein to the outside of the cell.

Question 7

Golgi Body

Answer 7

Sorts proteins for transport.

Question 8

Mitochondria

Answer 8

Provides energy for the RNA to produce protein.

Question 9

Cell Membrane

Answer 9

The thin wall covering the cell. It controls proteins entering and exiting the cell

Question 10

Cytoplasm

Answer 10

Contains water, sugar, and specific orders to ensure cell’s survival

Question 11

Gene

Answer 11

Segment of the DNA located at a specific place on a chromosome. It contains information to produce protein.

Question 12

Chromosome

Answer 12

A threadlike structure that carries genes

Question 13

Addition Mutation

Answer 13

A DNA that has a base added.

Question 14

Subtraction Mutation

Answer 14

A DNA that has a base substituted

Question 15

Substitution Mutagen

Answer 15

A DNA that has a base substituted

Question 16

Positive Mutagen

Answer 16

When the mutation or change is for better and increases the rate of survival

Question 17

Neutral Mutagen

Answer 17

When the mutation has not affected your cell concluding in no change

Question 18

Negative Mutagen

Answer 18

When the mutation or change is for worse and decreases the rate of survival.

Question 19

Mutagen

Answer 19

Substances or factors that cause mutations

Question 20

Gene Therapy

Answer 20

Therapy that aims to replace the mutated gene with a healthy gene to cure diseases.
