Q

Why is DNA replication called semi conservative?

A

Because it conserves half of the old parental double helix in each new double helix daughter strand.

Q

What is the chemical reaction of cellular respiration?

A

C6H12O6+6 O2——->

6CO2+6H2O+36ATP

19
Q

What is the difference between translation & transcription?

A

Translation is done in the nucleas & copies the message.
Translation is done on the ribosome and provides the message to make a protein.

20
Q

What occurs in each phase of interphase?

A

G1 cellular growth,
S-phase which is DNA replication
G2 prepares for mitosis,more growth

21
Q

What occurs in the cellular division phases?

A

Prophase, chromosomes condense, spindles form, nuclear membrane breaks apart, spindles attach to chromosomes.
Metaphase, chromosomes meet in the middle.
Anaphase, chromosomes pull apart.
Telophase, nuclear membrane and nucleus reform, chromosomes de-condense, spindles disappear.

22
Q

What is cytokinesis?

A

When they cell breaks apart, forms two identical daughter cells

23
Q

How many daughter cells are a product of mitosis versus meiosis? And what is the difference between those cells?

A

Mitosis creates two identical cells.

Meiosis creates four non-identical unique cells.

24
Q

What type of cells go through the cell cycle with mitosis and meiosis?

A

Mitosis-somatic cells.

Meiosis-germ cells.

25
Q

Which is the most devastating mutation?

A

Frameshift.

26
Q

What is the normal mutagen type?

A

Wildtype

27
Q

What is double-stranded, has the deoxyribose sugar, and nitrogenous bases T A G C?

A

DNA

28
Q

What is the genotype versus the phenotype?

A

Genotype is the genetic makeup.

phenotype is observable characteristics.

29
Q

Describe the anatomic position.

A

Reference position for the human body. Head is erect, eyes open, arm straight and by the sides, palms facing forward, knees straight, feet together, and flat on the ground.

30
Q

What is a body cavity?

A

Enclosed space inside the body

31
Q

What are the four main body cavities?

A

Cranial, vertebral, thoracic, Abdominopelvic

32
Q

What are the three sub cavities of the thoracic cavity?

A

Pleural cavity, mediastinum, and Pericardial

33
Q

What are the 2 sub-cavities of the abdominopelvic cavity?

A

Abdominal and pelvic

34
Q

What does the cranial cavity house?

A

Brain

35
Q

What does the vertebral canal house?

A

The spinal cord

36
Q

What does the thoracic cavity house?

A

Heart and lungs

37
Q

Lungs are located in a specific cavity known as?

A

Pleural cavities

38
Q

The heart is located in a specific cavity known as?

A

Pericardial cavity

39
Q

What does that mediastinum region house?

A

Between the plural cavities consisting of heart, esophagus, and vessels

40
Q

What does the abdominal cavity house?

A

Stomach, small intestine, most of the large intestine and various digestive organs (liver pancreas).

41
Q

What does the pelvic cavity house?

A

Terminal part of the large intestines and some of the reproductive organs of the female.

42
Q

When referring to the left or right regions of a patient, how do you determine which is correct?

A

Always the patients left or right

43
Q

What are the abdominal quadrants?

A

Right upper
left upper
right lower
left lower
