GAU to GAC is least likely to change phenotype of an organism.
<h3><u>Explanation</u>:</h3>
Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.
Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.
Both the GAU and GAC codes for aspartic acid. So the phenotype won't be affected much by this mutation
The process of importing free dna from the environment is called _transformation_.
The type of dna uptake that is dependent on viruses is called _transduction_.
The type of dna uptake that is dependent on transferable plasmids is called _cconjugation_.
Protozoa are Eukaryotic organisms, they show animal/plant like behaviors. Bacteria are prokaryotic, very tiny simple single celled organisms with no nucleus or mitochondria.
All the lactating females in a pride suckle cubs showing no favoritism for their own offspring. The reason for this is that each lioness is enhancing her own genes' success by helping to raise her sisters' offspring. Mothers give birth to up to 6 cubs at a time but litters of 2 or 3 are more common.
Hope this helped.
The answer is A- double carbon bond
