A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (
Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Chi Square test

See the attached file

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is __
earnstyle [38]

Answer:

The correct answer is 3' UCA 5'

Explanation:

The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.

Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.  

Therefore the correct answer is 3' UCA 5'.
