Scientists believed that atmosphere at that time was devoid of free oxygen and CO2 was present in excess. Before the complex life evolved on the Earth, the Precambrian Earth's ocean contained dissolved carbon dioxide.

true or false: genes code for chromosomes and chromosomes are responsible for the individual traits we observe. true correct! fa
Rainbow [258]

False, because chromosomes are architecturally very compact and genetic code for them, they are not responsible for the specific features we witness.

Contrary to appearance, chromosomes are very compressed physically, allowing for the containment of these enormous DNA structures within the cell nucleus. A human's chromosomes. The genetic code refers to the set of guidelines that living cells employ to convert data from genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. The ribosome does translation by linking genetic code amino acids in the order dictated by messenger RNA (mRNA) and employing transfer RNA (tRNA) molecules to transport amino acids.
