<span>In the mentioned case, transcription will result in B) the correct sequence of amino acids in the synthesized protein. According to the complementary rule, in the RNA, base complements are A-U (adenine - uracil) and G-C (guanine - cytosine). So, during the transcription of the following sequence of DNA "ATG GCC CAA TCG TGA", the correct sequence of RNA should be "UAC CGG GUU AGC ACU". As can be seen in the mutated sequence, the 4th codon is AGU instead of AGC. The effect the change will have on the synthesized protein will depend on the change in amino acid sequence. Since both AGU and AGC codons are for amino acid Serine. So, there will be no change in the sequence of amino acids in the synthesized protein.</span>

Amylase and starch are mixed and placed at 0 degrees. after the iki test, the solution turns black. a benedict's test yields a n
Fudgin [204]
The starch is not digested.

Amylase is the enzyme that digest starch to Maltose

In iki test, which is also iodine test, it is a test for presence if starch. It turns iodine color from brown to black. Therefore, we know that starch still exist if the color turns black.

Second, benedicts test is a test for reducing sugars, such as glucose or Maltose. Negative results mean no Maltose is detected. So, we can also figure out that no Maltose is produced.

Therefore, the original starch still exists and the product Maltose does not exists, so starch is not digested.
