a reaction that hydrolyzes a phosphodiester bond would cleave a dna molecule between a phosphate group and:
Gnoma [55]

Reactions that hydrolyze the phosphodiester bonds split the DNA molecule between the phosphate groups and the hydroxyl groups of the two sugar groups.

In DNA there is a covalent bond through a phosphate group that connects the hydroxyl group (OH) at the 5' position of the pentose sugar and the hydroxyl group at the 3' position of the pentose sugar of the next nucleotide. This covalent bond is called a phosphodiester bond because chemically the phosphate group is in the diester form.

In other words, the phosphodiester bond connects the sugar in one nucleotide to the sugar in the next nucleotide, so this bond simultaneously connects the two consecutive nucleotides to form a polynucleotide chain. If there is an enzyme that catalyzes the hydrolysis of covalent bonds that combine nucleotides, what happens is that the phosphodiester link between deoxyribose sugars will break.

The pubic symphysis connects the two hip bones anteriorly and provides a little movement during childbirth. Choose the most appr
My name is Ann [436]

Answer:

The most appropriate tissue to join the pubic symphysis -that provides resistance to pressure and stretch during childbirth- is fibrocartilage.

Explanation:

Options for this question are:

  • <em>A. Fibrocartilage.</em>
  • <em>B. Elastic cartlage.</em>
  • <em>C. Bone.</em>
  • <em>D. Hyaline cartilage.</em>

Fibrocartilage is made up of dense connective tissue rich in type I collagen fibers, hyaluronic acid and proteoglycans, which give it resistance to stretching and pressure.

Some ligaments are formed by fibrocartilage, in addition to the intervertebral discs and the junction of the pubic symphysis, allowing a certain degree of mobility to the associated structures due to their semi-elastic properties.

Hyaline cartilage, also made up of connective tissue, is less resistant than fibrocartilage.

Bone cannot form this junction, because it would not allow the relative mobility of the joint.

The elastic cartilage allows for stretching but not the strength needed to join the pubic symphysis.
