Answer:

B. the action of microRNAs that block translation of specific mRNA molecule

C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.

Explanation:

RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.

MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.

RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.

Answer:

Mitsumata

Explanation:

Mitsumata has been used since ancient times as a raw material for Japanese paper called “washi.” The tradition of using mitsumata as the raw material for making banknote paper has been passed down since it was first used for this purpose in 1879 (Meiji 12).

Answer:

Evolution refers to the change in the structure of an organism with the passage of million of years.

Explanation:

Evolution is the change in the structure of an organism with the passage of million of years. Evolution occurs due to two reasons, first from genetically while the other from adaptation to the environmental conditions. In genetically, the change in structure of animal comes from their parents whereas changes occurs due to adaptation of an organism in order to survive in the harsh climatic condition of the environment.

Amanda [17]

Answer:

A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

Explanation:

Transcription is the process in which DNA template is used to synthesize mRNA.

There are three steps of transcription:

Initiation

It is the process in which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.

Elongation

It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.

Termination

As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.

QUESTION:

A ribosome attaches to the initiation codon of a completed mRNA strand.

This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.

RNA polymerase moves along the template strand of the DNA creating an mRNA strand.

This is the incorrect answer choice as this event takes place in the process of elongation.

A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

This is the correct answer choice as this event takes place in the process of initiation of transcription

The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.

This is the incorrect answer choice. This event takes place in the event of termination of transcription.

Answer:

A pandemic is an epidemic disease extended across wide regions, thereby affecting many countries and even continents, while endemic diseases affect the people from only one country or a specific region. Human Immune Deficiency (HIV) is an RNA virus whose life cycle is composed of the following stages: 1) binding to the cell host and membrane fusion, 2) subsequent reverse transcription into DNA and integration into genome host 3) proliferation (i.e., successive replication cycles) by using the cellular machinery of the host 4) new assembly and budding of the virus. The acquired immune deficiency syndrome (HIV/AIDS) occurs when the host immune system is seriously damaged by the HIV infection, this being the latest stage of infection. It is known that HIV/AIDS is more prevalent in the female population, while according to ethnic groups, it is more prevalent in African-American and Hispanic/Latino populations in the USA. The life expectancy in HIV-infected patients has notably improved in the last years and, currently, people with this disease can expect to live over 70 years or even more.
