Back 7

LxH

Front 8

Surface Area

Back 8

LxWxsides

in squares

Front 9

Volume

Back 9

LxWxH

Front 10

chromatin

Back 10

Mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division.

Front 11

chromsomes

Back 11

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.

Front 12

chromotids

Back 12

A (sister) chromatid is one copy of a duplicated chromosome

Front 13

centrosome

Back 13

centrosome is an organelle that is the main place where cell microtubules get organised. They occur only in animal cells

Front 14

centromere

Back 14

A centromere is a region of DNA found in the middle of a chromosome where two identical sister chromatids come in contact. It is involved in cell division as the point of mitotic spindle.

Front 15

haploid vs diploid

Back 15

diploid cells have 2 sets of chromosomes, or 46 chromosomes.
haploid cells (such as sex cells) have only 1 set of chromosomes, or 23 chromosomes.

Front 16

transcription vs translation

Back 16

transcription: dna to rna

translation: rna to protein

Front 17

start codone

Back 17

AUG

Front 18

stop codones

Back 18

UGA, UAG, UAA

Front 19

rRNA

Back 19

In the cytoplasm, ribsomal RNA (rRNA) and protein combine to form a nucleoprotein called a ribosome.The ribosome serves as the site and carries the enzymes necessary for protein synthesis

Front 20

tRNA

Back 20

The tRNA reads the code and carries the amino acid to be incorporated into the developing protein.

Front 21

mRNA

Back 21

Messenger RNA (mRNA) is synthesized from a gene segment of DNA. The messenger RNA carries the code into the cytoplasm where protein synthesis occurs.

Front 22

Front 23

centriole

Back 23

cell organelle, near the nucleus in the cytoplasm of most eukaryotic cells, that divides in perpendicular fashion during mitosis and organize microtubules during cell division...
