If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?
Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.

Define what terms origin, insertion and tendon
artcher [175]

Answer:

<u>Origin:</u> In biology, origin can be described as the location where the muscle joins a stationary bone and as a result, no movement occurs.

<u>Insertion: </u>In anatomy, insertion can be described as the point of attachment which allows movement of a bone to occur. It moves when the muscles contract.

<u>Tendon:</u> In biology, the tendon can be described as a type of connective tissue which attaches a bone to a muscle.

A biologist working in a lab adds a compound to a solution that contains an enzyme and substrate. This particular compound binds
tigry1 [53]

Answer:

The correct answer is C) The compound is an allosteric inhibitor.

Explanation:

An inhibitor works in many ways, but this particular one binds to the allosteric site in the enzyme causing a decrease of the enzymatic activity. When this situation happens, the inhibitor doesn't bind to the active site, but it changes the enzyme's shape so it cannot work properly anymore.
