Which of the chains of amino acids corresponds to the nucleotide sequence aauggcuac
maxonik [38]
The sequence AAU GGC UAC is composed of three codons each of which codes for a different amino acid. AAU codes for the amino acid called threonine. GGC codes for the amino acid called glycine UAC codes for the amino acid called tyrosine. So the chain will read  threonine-glycine-tyrosine. There are 64 possible 3 - letter combinations of DNA coding units A, C, G and T. Of these, there are three stop or non- sense codons that do not code for any amino acid, while the remaining 61 code for different amino acids.

Yeasts are unicellular microorganisms of the fungi kingdom that can digest sugars using both aerobic and anaerobic cellular resp
tiny-mole [99]

Answer:

This question is incomplete as it does not contain the representation of the experiment, however, based on general understanding, the answer is:

Carbon dioxide (CO2)

Explanation:

Yeasts, as stated in this question, are living unicellular organisms that belong to the KINGDOM FUNGI. They employ both the aerobic (with oxygen) and anaerobic respiration (without oxygen) in breaking down sugars. However, both methods of cellular respiration gives off CARBON DIOXIDE (CO2) as a byproduct.

Therefore, when a yeast is placed in a balloon in accordance to this experiment and is allowed to perform respiration either aerobically or anaerobically, it gives off CO2 gas, which causes the balloon to expand.
