The correct answer for the question that is being presented above is this one: "a. Paleozoic." If you see a fossil fish in a museum that is labeled one of the earliest fish known, the era that that fish belong is surely Paleozoic era. It is one of the early eras of the history of the species.

Answer:

The three processes from left to right are:

Replication DNA Trancription RNA Translation Protein

Explanation:

The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:

DNA Replication
Transcription
Translation

DNA Replication:

DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.

Transcription:

Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.

Translation:

Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.

Humans have 23 pairs of chromosome in every body cell. Even one extra chromosome causes death or serious disorders. For example,

tamaranim1 [39]

Explanation:

In the majority of cases, the extra copy of chromosome 21 comes from the mother in the egg.

In a small percentage (less than 5%) of cases, the extra copy of chromosome 21 comes from the father through the sperm.

In the remaining cases, the error occurs after fertilization, as the embryo grows.

Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on d

lianna [129]

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.
