Answer:
Density = Mass/Volume
Density = 216cm3/64g
Density = 3.375 g/cm3

Answer:
During transcription, a strand of RNAm is obtained from DNA.
On the other hand, the translation is the process of peptide synthesis, from mRNA. This last process occurs in the cytoplasm, and is mediated by the ribosomes.
Regarding your last question, this last process is called translation, since in this process we pass from genomic language (nitrogenous bases) to amino acids (constituents of peptides).
Answer:
The answer is Option B the nucleus
Explanation:
Genetic information in prokaryotic cells is carried on a single circular piece of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no enclosing membrane, so there is no true nucleus, but simply a concentration of DNA known as a nucleoid.
and DNA is present in the nucleus. Therefore option B is correct

NACL is the correct answer
Answer:
C. Gene trees are only useful studying the relationships of sequences from different species.
Explanation:
Gene tree traces the evolutionary history of a particular gene. It includes all the events like duplication and speciation. It helps to study the relationship of genes from different species. Often these are orthologous genes which came form the same ancestor and code for the same protein indifferent species. Gene tree also helps to study the relationship of genes in the same species. Often these are paralogous genes which evolved by duplication and code for similar but not identical proteins in the same species. Hence, the statement that gene trees are only useful for studying the relationships of sequences from different species is incorrect.
