Answer:

Ribosomes located in the cytoplasm

Explanation:

Translation is the second process involved in protein synthesis. It is the process whereby protein is synthesized from an mRNA molecule. Initially, the information contained in the DNA molecule is transcribed into RNA molecule in the nucleus of eukaryotic cells.

The mRNA molecule then leaves the nucleus and attaches to a complex of RNA and protein called RIBOSOME, which is found floating freely in the cytoplasm or attached to Endoplasmic Reticulum. The Ribosome is an organnelle regarded to be the site of protein synthesis.

Hence, translation starts when the mRNA molecule attaches to the Ribosome in the cytosol of the cell.

Answer:

Option E

Explanation:

As per Hardy Weinberg's second equation of equilibrium, the sum of genotype frequency for all possible genotype in a given population with two allele is equal to

$p^2 + q^ 2+2pq = 1\\$

Substituting the given values in above equation, we get -

$0.16 + 0.64 + 0.20 =1\\ p^2+q^2+2pq= 1$

Hence, second equation satisfies.

As per Hardy Weinberg's first equation of equilibrium, sum of all allele frequencies is equal to 1

$p + q=1\\\sqrt{0.16} +\sqrt{0.64} \\0.4+0.8 = 1.2\neq 1$

Hence, this population is not in Hardy weinberg's equation.

After one generation, the frequency of T allele is $0.4$ which is the same as that of frequency of T allele in previous generation

Also as per hardy Weinberg's theory , if a population genotype frequency sums up to 1, it is in equilibrium if its allele frequency sum is also 1.

But here in 2004. This was not the case.

However, Weinberg has stated that the population which is not in equilibrium can reach equilibrium after one generation only with a new set of genotype frequency and allele frequencies.

Hence, in this case there is a possibility that allele and genotype frequencies have readjusted to sum up to 1

If frequency of the T allele is $0.4$

New frequency of the t allele would be

$1- 0.4\\= 0.6$
