Question 15

translation

Answer 15

the process in which amino acids form into a protein

Question 16

cytokinesis

Answer 16

the cell divides into two daughter cells exactly like the parent cell

Question 17

haploid

Answer 17

one set of chromosomes in an organisms cell

Question 18

asexual reproduction

Answer 18

a production of offspring when one parent donates all of the genetic info

Question 19

diploid

Answer 19

2 sets of chromosomes in an organisms cell

Question 20

sexual reproduction

Answer 20

the production of an offspring when 2 parents give 50% of their genetic info each

Question 21

DNA

Answer 21

deoxyribosenucleic acid, carries genetic info

Question 22

fission

Answer 22

elongation and separation of bacterial cells

Question 23

gene

Answer 23

determines traits, each person donates a set to the offspring

Question 24

budding

Answer 24

offspring grows off the parent

Question 25

mRNA

Answer 25

messenger RNA, breaks down genetic code to bring to ribosomes

Question 26

regeneration

Answer 26

offspring is produced by a cutting from a parent plant

Question 27

rRNA

Answer 27

help translate the mRNA into a protein

Question 28

spore formation

Answer 28

specialized cells are released by the parent, if landed in a favorable environment, offspring will be produced

Question 29

tRNA

Answer 29

transport RNA, brings the code(DNA) to the ribosome

franklin, watson, and crick

Question 34

spindle fiber

Answer 34

control the movement and separation of chromosome during mitosis

transcription

Answer 36

change writing
