Answer:

E. All of the above statements are

Explanation:

Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.

A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).

Answer:

They do not belong to the same population

Consider a population of wildflowers in which the frequency of the red allele cr is p = 0.7. what is the frequency of the white
anygoal [31]
I) Alleles is the alternative form of a gene or in other terms the variant form of a gene. If there are two alleles at a locus p and q are used to represent their frequencies. Frequencies of all alleles in a population will add up to 1. 
Therefore, in this case if red allele CW is p=0.7, then the frequency of the white allele in this population (q) is 0.3.

ii) From the punnet square the expected genotypes frequencies in the offspring generation will be 0.49 CRCR (red flowers, o.42 CRCW (pink flowers) and 0.09 CWCW (white flowers).
