Answer:
Gilbert Newton Lewis ForMemRS was an American physical chemist and a former Dean of the College of Chemistry at University of California, Berkeley. Lewis was best known for his discovery of the covalent bond and his concept of electron pairs
Explanation:
Out of the following given choices;
a. RNA is not able to carry information.
b. RNA is more complex in structure than DNA.
c. RNA would get stuck on the inner surface of the nuclear
membrane.
d. primitive cells would not let RNA molecules across their
membranes.
e. no conditions exist that favor production of both the
sugar and base parts of an RNA monomer
The answer is E. According to evolution, the best adaptable
trait in an environment is highly preserved.
The chemical properties of RNA make large RNA molecules inherently fragile, and
they can easily be broken down into their constituent. Therefore it is unconvincing that was it was used to store critical
genetic information.
Answer:
33.3 cM
Explanation:
Parent 1: blue shell, long antenna : BBLL
Parent 2: green shell, short antenna : bbll
BBLL X bbll :
F1 : BbLl ( blue shell, long antenna )
BbLl X bbll :
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = (Number of recombinants/ Total offspring)*100
= (80/240) * 100 = 33.33 %
Map distance = recombination frequency
Hence, map distance = 33.3 cM
