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
Definitely belongs to the fungi kingdom!
did you hear the joke about the fungus???
... I could tell you, but it'd take some time to grow on ya!
goodluck my friend, :-)
The smallest bone in the body is the stapes and it is the third bone of the three ossicles in the middle ear.
Answer:
Option (d).
Explanation:
Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.
Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.
Thus, the correct answer is option (d).
Answer:
they are rocks, water, air, soil and living things
