Which molecule contains the condon that is read during translation.
Mama L [17]

Answer:

The molecule that contains the codon during translation is mRNA or messenger RNA (option C).

Explanation:

The mRNA is the product of the transcription of the information contained in the DNA, originating a nitrogenous base sequence complementary to the sequence present in the originating DNA.

The sequence of nitrogenous bases in the mRNA is translated into <u>fragments of three nitrogenous bases</u>, called triplets or codons, each of which encodes a specific aminoacid, which will be incorporated during protein synthesis, in the order previously determined.

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
