Sometimes the sequence of dna gets mutated and an adenine is paired to a cytosine. Why is this interaction unstable?
kirza4 [7]

Answer;

-Because the chemical groups that form hydrogen bonds are in the wrong positions.

Explanation;

-A base pair is any of the pairs of nucleotides connecting the complementary strands of a molecule of DNA or RNA and consisting of a purine linked to a pyrimidine by hydrogen bonds.

-The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA or in hybrid DNA-RNA pairing. A mutation in the sequence of DNA that makes an adenine to be paired with a cytosine results to an unstable interaction because the chemical groups that form hydrogen bonds are in the wrong positions.

Which type of movement is characteristic of the articulation between the tibia and fibula with the talus?
jonny [76]

Solution:

The function and mobility of each joint depends on its anatomical design. Joints that permit no movement or slight movement are common in the axial skeleton where basic structural support and protection  is expected. Joints that are freely moveable are common in the appendicular skeleton where mobility is required. Is known as articulation.

The tibial collateral ligament reinforces the medial side of the knee joint and the fibular collateral ligament reinforces the lateral side of the knee joint. Two popliteal ligaments reinforce the posterior side of the knee joint.
