Ans.
The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.
The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.
The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.
The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).
Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.

<h2>
Answer: Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.</h2>
Explanation:
<h2>The information carried by a DNA molecule is in Genetic information resides in the order of the nucleotides on a DNA molecule. ... They hypothesized that there must be a code that linked the nucleotide sequence in a gene to the amino acid sequence in a protein. Each nucleotide code is called a codon.</h2>
Answer:
Biofuels like fuel from microalgae are very costly as compared to fossil fuels.
Explanation:
The cost of biofuels is too high as compared to that of fossil fuel. For instance,
the cost of 1 gallon of algal fuel is $32.81 per gallon while cost of diesel is $2.9 -3.2 per gallon.
However, biofuels are very environment friendly as compared to that of fossil fuels.
Answer:
<em>hazardous waste container</em>
Explanation:
In a lab, hazardous waste container contains all the waste which can be dangerous or infectious. Hence, it should be properly handled and disposed of. Due to the cut in the lab, the blood of Lousia might contain infectious microorganisms. Hence, after cleaning the blood with paper towels, the paper towels should be discarded in the hazardous waste container as the paper towel might contain hazardous microorganisms.
