are two epigenetic mechanisms that can prevent DNA from being accessible to transcription molecules. When the DNA is unwound, mo

lecules that bind to determine when and how to transcribe genes. When gene transcription begins, a special type of protein known as binds to a promoter and assembles RNA. An activator is a transcription factor that binds to and promotes transcription. A repressor is a transcription factor that binds to and prevents transcription. Even if a gene is transcribed, its ultimate translation and expression can be silenced by

Answer:

microRNAs

Explanation:

Within the cell, there are different types of regulatory non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), small-interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs), long ncRNAs, etc., which are able to regulate gene expression. miRNAs are evolutionary conserved small ncRNAs (typically 18-23 nucleotides in length) known to inhibit gene expression by base-pairing with complementary target mRNAs, and thus trigger RNA interference (RNAi) pathways (e.g., mRNA degradation, inhibition of translation, etc). These miRNAs form part of a ribonucleoprotein complex named RNA-induced silencing complex (RISC) that acts to trigger RNAi mechanisms.

In which position are the earth, moon, and sun during a new moon?
dimaraw [331]

Answer:

A. Moon is between the Sun and Earth

Explanation:

The new moon stage is the faze in which we can not see the Moon from Earth. In this stage, the Moon is lacking from the sky, or rather we can not see it because it is totally dark from the side that is facing the Earth. The reason for this is that the Moon is located between the Sun and the Earth. The Sun is making half of the Moon bright as it always does, but in this stage it is the half of the Moon that is facing the Sun, while the other half that is facing the Earth is totally dark as it doesn't receive any sunlight at that time.

Which common practice puts the nurse at liability for invasion of patient privacy?
harina [27]

Answer;

-The nurse gives information about the patient to telephone callers who inquire about the patient.

Explanation;

-Medical care requires the invasion of privacy. Patients must expose their innermost thoughts, their bodies, and their sickrooms to strangers. But to protect human dignity, health providers should limit invasions to those necessary to accomplish the goals of their patients.

-Invasion of privacy and confidentiality are of critical legal and medical concern. The right to privacy means that a client has the right to expect that his or her property will be left alone. Healthcare individuals may be charged with trespassing, illegal search and seizure, or releasing private information (even if the information is true).

Do abiotic elements interact with biotic elements in an ecosystem?
myrzilka [38]

Answer:

<em>Yes, the abiotic components interact with the biotic components in an ecosystem.</em>

Explanation:

The abiotic components are the non- living components of an ecosystem. The biotic components are the living components of an ecosystem. Abiotic factors such as sunlight, temperature etc directly affect the biotic components.

For example, the light of the sun is an abiotic component which provides energy to the biotic components, plants, to produce food. Soil is also an abiotic component which provides nutrients and water for the plants which are biotic components.
