-

What is the 4th and Final phase of Mitosis 

when-nuclear envelope forms

around the 2 new nuclei

-
What is the oval structure inside the nucleus that makes the ribosomes

What  is - The offspring of many generations that have the same trait.  Ex: short pea plants always come from short parent plants

-
What is- The offspring of genetically dissimilar parents, especially the offspring produced by breeding plants or animals of different varieties, species, or races. Example: offspring inherits 1 allele for tallness from pure bred tall plants, and 1 allele from a purebred short plant for shortness.  The off spring will be a ____ and it will be tall because tallness is dominant.
-
WHAT is-the allele trait that is always hidden when the dominant trait is around. the dominant allele always wins when its around - IF  a dominant gene for tallness from one parent and a recessive gene for shortness from the other parent pair up, tallness will be inherited because its dominant.  You need two shortness genes to pair up to inherit shortness.

-

 What is - A trait that is expressed over another trait. 

Example: 

So if the brown hair gene is a ______  _______ over blonde hair and you have  a blonde and a brown hair gene from each of our parents,  you’ll have brown hair.

final stage of the cell cycle,

-completes cell division cycle-

Cytoplasm pinches middle of the cell - cell divides,

then organelles are distributed

to each new daughter cell

-

what is - the 2nd stage of the Cell Cycle -

when Cell Division occurs 

(= parent cell divides into 2 daughter cells)

There are phases of Mitosis  ( P.Mat)

Prophase,  Metaphase, Anaphase, Telephase)

-

- 1st stage in the cell cycle

cell grows


getting ready to divide & replicate its DNA

during Mitosis

-

What is

The orderly set of events of a cells growth and division

(AKA-the life cycle of a cell-which has 3 parts: Interphase, Mitosis and Cytokinesis)  called

-

What isto make a duplicate or twin

of one's self  called

-

- What are-Many genes joined together-  

During prophase, Chromatin condenses and the DNA replicates to form two rods called chromatid,

exact copies of each other.

This double rod of chromatids is called a__________

-

WHAT IS THE formation of sex cells (sperm and egg)

- the number of chromosomes is halved 

-It  has 4 phases, like Mitosis,

but it’s phases repeat,  - replicate 2 times,

so there’s Prophase 2 and metaphase 2 and so on 


 

-

 

WHAT IS THE

-

One of the

4 nitrogen bases

in DNA that begins with a T

-

 

 

WHat are vacuoles

-

Because they are going to join up

with other sex cells

from the other parent

to make  offspring (baby) cells.

-Then it will add its half to the other parent's half

to make one complete cell

-

The spindles are pulling the chromosomes

towards opposite poles of the cell

where they will become part of 2 new nuclei for 2 new daughter cells- in Mitosis and Meiosis - it will happen 2 times in Meiosis.

It is called just plane anaphase in Mitosis.

-

YOu can tell this is  _________ , of MEIOSIS   because there are 2 cells now

not just one like there is in Mitosis, whose spindles are pulling the chromosomes towards opposite poles ,

getting ready for the second split in Telephase, so that there will be 4 daughter cells 

-

THESE ARE 2 PICTURES of 1 cell

picture 1- BEGINNING OF _______

picture 2 - THE END OF ________

YOU CAN TELL BECAUSE:

picture  1-YOU CAN'T SEE ANY CHROMOSOMES

picture 2- now THE CHROMATIN HAVE Condensed/Fattened up INTO CHROMOSOMES; and Nuclear Wall is breaking up, losing its shape. 

What you cant see in the photo = are the CENTROMERES going to opposite poles of the cell while spindle fibers make a bridge between them.

-

In this phase of Mitosis & Meiosis,

the chromosomes(in red) have all split

and have been pulled by the spindle fibers to opposite poles of the cell.

2 new nuclei have formed and the cell is ready for the last phase - when it will elongate

before Cytosis

-

In this phase of Mitosis and Meiosis, the chromosomes are all lined up at the equator of the cell.  The spindle fibers are there too, attached to the chromosomes. they look like faint squiggly lines 

ready for the next phase when they will pulled apart chromosomes to either pole of the cell
