Nadusha1986 [10]

Answer:

The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:

Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.

These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.

describe and explain the adaptations of sperm and ovum that enables fertilisation and early development of the embryo to occur​
Mekhanik [1.2K]

The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.

<h3>What is fertilization and embryo development?</h3>

In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.

With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.

What factors influence the amount of DNA you have?
Free_Kalibri [48]

The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.

The quantity and quality of DNA can be greatly improved by performing PCR.

* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.

The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
