BIOL 3001 Quiz Questions With Correct
Answers
____________ |is |a |series |of |techniques |by |which |biomolecules |can |be |separated |based |on |
size, |length, |and/or |shape |- |CORRECT |ANSWER✔✔-electrophoresis
You |will |be |using |a |new |computer |program |this |week |called |ELS |which |stands |for |
Electrophoresis |Learning |System |- |CORRECT |ANSWER✔✔-True
When |using |the |ELS |program, |the |samples |should |be |heated |for |a |minimum |of |__________ |
minutes |- |CORRECT |ANSWER✔✔-5
The |fragments |of |DNA |we |will |be |examining |this |week |in |lab |will |be |separated |based |on |
fragment |_________ |- |CORRECT |ANSWER✔✔-length
why |it |is |so |important |to |control |the |time |of |gel |electrophoresis. |what |might |happen |if |the |gel
|runs |too |short |of |a |time |versus |too |long |of |a |time. |- |CORRECT |ANSWER✔✔-1. |not |enough |
resolution/separation |of |the |band |fragments |if |the |gel |runs |too |short |making |it |difficult |to |
interpret |and |2. |loss |of |data |if |bands |are |run |off |the |end |of |the |gel
The |final |step |in |the |ELS |program |is |to |develop |your |gel |so |that |the |DNA |fragments |become |
visible. |This |technique |uses |a |small |amount |of |radioactive |phosphorus |and |is |called |
___________ |- |CORRECT |ANSWER✔✔-autoradiography
The |DNA |fragments |used |in |this |lab |will |exhibit |a |very |simple |mode |of |inheritance, |which |is |
___________ |- |CORRECT |ANSWER✔✔-co-dominance
When |using |microsatellites |as |genetic |markers, |as |we |do |in |this |lab |exercise, |it |is |easy |to |
identify |heterozygotes |because |they |all |show |2 |bands. |True |or |False? |- |CORRECT |ANSWER✔✔-
True
, Genotyping |also |provides |us |with |another |critical |lesson, |namely |that |__________ |- |CORRECT |
ANSWER✔✔-uncertainly |exists |in |all |scientific |studies
The |scientific |name |(genus |species) |for |the |fruit |fly |(red-eyed |pomace |fly) |is? |- |CORRECT |
ANSWER✔✔-Drosophila |melanogaster
How |many |PAIRS |of |chromosomes |doe |fruit |flies |have? |- |CORRECT |ANSWER✔✔-4
For |the |Lygaeus |Mode |of |Sex-determination, |list |the |chromosome |assignment |for |each |gender
|- |CORRECT |ANSWER✔✔-Female: |XX
Male: |XY
Why |are |the |Parentals |of |most |crosses |homozygous |(1 |dominant |and |1 |recessive)? |- |CORRECT |
ANSWER✔✔-all |offspring |in |first |Filial |(F1) |will |be |heterozygous
A |total |of |428 |offspring |are |produced. |Some |are |red |and |some |are |blue. |Given |the |cross |that |
you |made, |you |expected |a |ratio |of |3 |red |: |1 |blue. |How |many |red |offspring |did |you |expect |
from |the |428 |progeny? |- |CORRECT |ANSWER✔✔-321
A |total |of |3852 |offspring |are |produced. |Some |are |red |and |some |are |blue. |Given |the |cross |that |
you |made, |you |expected |a |ratio |of |3 |red |: |1 |blue. |How |many |blue |offspring |did |you |expect |
from |the |3852 |progeny? |- |CORRECT |ANSWER✔✔-963
A |total |of |424 |offspring |are |produced. |Some |are |red |and |some |are |blue. |Given |the |cross |that |
you |made, |you |expected |a |ratio |of |3 |red |: |1 |blue. |How |many |blue |offspring |did |you |expect |
from |the |424 |progeny? |- |CORRECT |ANSWER✔✔-106
In |a |recent |survey |of |students |in |General |Genetics, |102 |identified |themselves |are |female |and |
171 |as |male. |Use |Chi-Squared |analysis |to |determine |if |this |sample |fits |an |expected |ratio |of |
