A student builds a model of a DNA strand.
insens350 [35]

Answer:

There is no attachment to this question, however, the base sequence on the model built by the student is: CAGCCATC

The options of the bases on the complementary model are:

A) CTACCGAC

B) GUCGGUAG

C) GTCGGAAG

D) GTCGGTAG

The answer is D

Explanation:

A DNA molecule is a polymer biomolecule made up of nucleotide bases. It is a double stranded molecule, with each strand containing nucleotides held together by hydrogen bonds. The pairing of nucleotides in one strand of DNA to another follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine binds to Thymine (A-T) while Guanine binds to Cytosine (G-C).

According to this question, a student builds a model containing the base sequence: CAGCCATC, the model that contains bases that are complementary to the ones built by the student is: GTCGGTAG

Enzyme hot spring graphing what enzymes probably came from the digestive tract of the mondoni
AURORKA [14]
I found the full exercise on the internet and it describes that there are three enzymes and you want to know which are the two enzymes from the <span>digestive tract of the mondoni and which one is the enzyme from a hot spring.
Attached are two graphs from the analysis of the activity of these enzymes regarding temperature and pH. I found these graphs with the full exercise.
The enzymes that probably came from the </span>digestive tract of the mondoni were enzymes A and B. These enzymes were resistant two lower levels of pH which indicates that they could be present in a <span>digestive tract, which tends to be acidic, while the enzyme C does not tolerate lower pH levels. Enzymes A and B were also more active when in lower temperatures that match temperatures of a normal living organism, whereas enzyme C was more active in higher temperatures matching its probable provenience - a hot spring.</span>
