Which statement best explains how the genetic code is universal? * The shape of a DNA molecule is the same in different species.
A DNA sequence codes for the same proteins in different species. The nucleotide ratios in the DNA molecule are different between species. DNA sequences are unique for each species.
A DNA sequence codes for the same proteins in different species
Explanation:
All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Antibiotics added to livestock feed have been found to increase their growth rate, reduce incidence of infection, reduces mortality and improve feed conversion ratio or feed efficiency.
