DNA

Question 0

Double helix unwinds, helicase unzips dna by breaking hydrogen bonds, polymerase pairs each of two strands with the correct nitrogen base, lipase glues together different fragments of lagging strands. What’s this process?

Answer 0

Answer 3

Crossing over

Question 4

Cell growth and reproduction. Cell divides in two and creates replica

Answer 4

Mitosis

Question 5

Cellular Reproduction which chromosomes are are reduced by half through separation of chromosomes creating two haploid cells

Answer 5

Meiosis

Question 6

Stages in Mitosis?

Answer 6

Prophase, Metaphase, Anaphase, Telephase

Question 7

Answer 7

Prophase

Question 8

Chromosomes meet in middle, spindle fibers attach to each chromatid at centromere

Answer 8

Metaphase

Question 9

Answer 9

Anaphase

Small

Question 14

When is DNA in chromatin form?

Answer 14

S phase of Interphase

Question 15

When does DNA organize itself into chromosome form?

Answer 15

It is in chromosome form when it moves into the daughter cells

Question 16

When does DNA synthesize?

Answer 16

S of Interphase

Question 17

When does the cell grow?

Answer 17

G1

Question 18

When does the cell divide?

Answer 18

Telephase

Question 19

What holds the sister chromatids together in chromosome structure?

Answer 19

Centromere

Question 20

What’s the difference between cell division in plants and animals?

Answer 20

During Mitosis in animals, we find a specific structure called a centrosome that becomes the center of spindle thread.
