Kobotan [32]

The mother of the bunnies is white while their father is black. The independent assortment of the genes during the formation of gametes ensures that each parent contributes same amount of the genetic information to the offspring. The more number of black bunnies than white is because of the dominance of the gene coding for the black fur trait over the white fur trait.

Hence, the correct answer is 'Option F'.

How does genetic information flow in an organisim
prisoha [69]

Answer:

DNA to mRNA to Proteins

Explanation:

The central dogma of molecular biology describes the flow of genetic information in cells from DNA to mRNA to protein. The genes specify the sequence of mRNA molecules, which in turn specify the sequence of proteins.The translation of this information to a protein involves three mRNA nucleotides( codons) that correspond to an amino acid in the polypeptide sequence.

During transcription, a DNA sequence is read by RNA polymerase, which produces a complementary, antiparallel RNA strand. If the transcribed gene encodes a protein, the result of transcription is messenger RNA (mRNA), which produces protein in the process of translation.

During translation, a cell decodes the mRNA and assembles the a new polypeptide chain. The tRNA translates the sequence of codons on the mRNA strand. The tRNA transfers a free amino acid from the cytoplasm to a ribosome, where it is attached to the new polypeptide chain. tRNAs continue to add amino acids to the new end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
