Kisachek [45]

Answer: Placebo effect

John is experiencing placebo effect where the pill that contains no pain killing medication has given pain relief to John. A placebo is a substance with no therapeutic effect but sometimes improves patient’s condition. This is due to patient’s expectation that the pill they take can help or ease the pain they have even if no active ingredient is present.

Therefore, the effect is more than positive thinking or believing that a treatment will work by creating a stronger connection between the brain and body as they work together.

Goryan [66]

Answer:

A. Homologue.

B. Chiasma.

C. Synaptonemal.

D. Synaptonemal.

E. Synapsis.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Matching the various terminologies in genetics with their description, we have;

A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.

C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.

D. Synaptonemal: four chromatids are held together by a zipper-like structure.

E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.
