Answer 1

study of inheritance

Question 2

genome

Answer 2

all genetic material in a cell

Question 3

gene

Answer 3

segment of dna that encodes for a function or a product

Question 4

chromosome

Answer 4

tightly coiled dna

Question 5

base pairs

Answer 5

DNA- A-T C-G

RNA- A-U C-G

Question 6

genetic code

Answer 6

dna sequence

Question 7

genomics

Answer 7

science that studies the genome

Question 8

genotype

Answer 8

dna sequence

Question 9

phenotype

Answer 9

observed genetic property

Question 10

RNA

Answer 10

ribose nucleic acid
single stranded nucleic acid
contains ribose sugar
base pairs A-U C-G

Question 11

DNA

Answer 11

deoxyribose nucleic acid
doubled stranded nucleic acid
contains deoxyribose sugar
base pairs- A-T C-G

Question 12

what is dna replication

Answer 12

replicating dna

Question 13

what are the fundamentals of dna replication

Answer 13

2 daughter cells created by a parent cell
23 paternal cells and 23 maternal cells
daughter cells contain 48 chromosomes
dna replication is semiconservative, bi-directional, and has a specific direction

Question 14

what is the short version of the cell replication cycle also known as dna replication

Answer 14

G1, S phase, G2 , mitosis –> 2 cells

Question 15

which phase does dna replication occur in the cell cycle

Answer 15

S phase

Question 16

what does it mean that dna replication is semiconservative

Answer 16

dna replication starts from an old cell (parent cell) and from that creates 2 new cells by complementary bonding

Question 17

what is the direction that dna replication occurs in

Answer 17

5” prime PO4 end to 3’ prime end OH group

Question 18

what does it mean that dna replication is bi-directional

Answer 18

helicase unwinds DNA in both directions
