pleitrophy

Answer 1

one gene affecting many traits

Question 2

epistasis

Answer 2

one gene affects another when it is expressed (golden lab)

Question 3

multiple alleleism

Answer 3

more than 2 alleles can exist (blood type)

Question 4

codominance

Answer 4

having both of the phenotypes (blue flower with red spots)

Question 5

proto onecogenes

Answer 5

un mutated normal genes

Question 6

onecogenes

Answer 6

cancerous genes

Question 7

Dihybrid cross

Answer 7

comparing 2 traits 9:3:3:1

Question 8

DNA polymerase 1

Answer 8

Removes RNA primer and replaces with DNA primer

Question 9

DNA polymerase 3

Answer 9

Synthesizes new DNA based on parental strand, needs RNA primer

Question 10

sliding clamp

Answer 10

binds to poly 3 and enhances synthesizing

Question 11

Proof reading

Answer 11

poly 3 does this DURING replication - replaces one nucleotide that is incorrect

Question 12

Mis match pair

Answer 12

poly 1 does this AFTER replication, replaces mismatch pair and ligase seals the gap

Question 13

feedback inhibition

Answer 13

this is what tryptophan does - when there is alot of it - it shuts it off

Question 14

repressible operon

Answer 14

lac operon - when there is none of it, it is off

Question 14

miRNA

Answer 14

silences genes
