3 stages where gene expression is regulated (2023)

Biology Elementary School


answer 1


Gene regulation is the process of controlling which genes in a cell's DNA are expressed (used to produce a functional product, such as a protein).

Different cells in a multicellular organism can express very different sets of genes even though they contain the same DNA.

The set of genes expressed in a cell determines the set of proteins and functional RNAs it contains, giving it unique properties.

In eukaryotes, such as humans, gene expression involves many steps, and gene regulation can occur at any one of these steps. However, many genes are regulated primarily at the transcriptional level.


Your incredible body contains hundreds of different types of cells, from immune cells to skin cells and neurons. Almost all of your cells contain the same set of DNA instructions - so why do they look so different and do jobs so different? The answer: different genetic regulation!

Gene regulation makes cells different

Gene regulation is how a cell controls which genes, among the many genes in its genome, are "turned on" (expressed). Thanks to genetic regulation, each type of cell in your body has a different set of active genes – despite the fact that almost every cell in the body contains the exact same DNA. These different patterns of gene expression cause your different cell types to have different sets of proteins, making each cell type uniquely specialized to do its job.

For example, one of the functions of the liver is to remove toxic substances like alcohol from the bloodstream. To do this, liver cells express genes that encode subunits (pieces) of an enzyme called alcohol dehydrogenase. This enzyme breaks down alcohol into a non-toxic molecule. The neurons in a person's brain do not remove toxins from the body, so they keep these genes unexpressed or "turned off". Likewise, liver cells don't send signals using neurotransmitters, so they keep the neurotransmitter genes turned off.

What are some differences and similarities between sexual and asexual reproduction?



Asexual reproduction produces offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

There are several different forms of asexual reproduction. These include budding, where the offspring grow outside the parent's body, and budding, where the parent releases a specialized mass of cells that will become a new individual.

There are two types of sexual reproduction. Syngamy is the permanent fusion of two haploid gametes to create a zygote. In humans, this is called fertilization. Conjugation, on the other hand, is a temporary fusion using a cytoplasmic bridge. This is especially seen in bacteria, which pass DNA through the bridge.

Asexual reproduction is reproduction that occurs without interaction between two different members of a species. Cells divide using mitosis, where each chromosome is copied before the nucleus divides, where each new cell receives identical genetic information

Sexual reproduction is reproduction that requires a male and female of the same species to contribute genetic material. Special cells called gametes are produced by meiosis, which halves the number of chromosomes in each resulting cell. These cells are called haploid gametes. Fertilization occurs when two gametes - one from a male and one from a female - combine to produce a diploid zygote with its own individual genetic makeup. Hope this helps

Do fossils provide a complete record of all extinct species that have lived on Earth? Why or why not? A. Yes, because all species left fossils.
B. Yes, because the characteristics of many species can be derived from a single fossil.
C.No, because many species became extinct without leaving fossils.
D. No, because fossils decay after about 65 million years


C no, because many species went extinct without leaving fossils


C. No, because many species became extinct without leaving waterfalls.


Not all species will leave fossils, and we cannot infer things about other species from a fossil of a particular species.

Answer: dna



Hello. This question is incomplete. The complete question is:

“Which of the following is not an ocean resource

a- sand b- common salt c- natural gas d- silver"


d- talk


Silver is not an oceanic resource, but a mineral, a metal, a chemical element that can be found on the Earth's surface. As silver is a mineral, we cannot call it an ocean resource, but a mineral resource.

A mineral resource is an inorganic substance such as silver. There are other mineral resources such as iron, aluminum, manganese, sulfur, among others.




The sea is the most valuable resource on earth. At least even some marine resource vegetables are also related to the sea. Most fish are also related to the sea.

But since my thinking is made of plastic

Will Give Give Brainliest And 5 Star /// Which of the following technologies will best help a farmer who wants to increase crop production on his farm? Cloning because it can create identical copies of crops to increase genetic diversity
Genetic engineering because it helps to increase the diversity of crops, making them stronger
Genetic engineering because it helps crops grow bigger and faster and resist disease and insects
Cloning because it can create genetically modified crops that can withstand harsh weather conditions



Genetic engineering because it helps crops grow bigger and faster and resist disease and insects


Cloning does not increase genetic diversity because all plants will be exactly the same. Cloning does not involve the genetic modification of genes, so A and D are misspelled points. Genetic engineering can be done to produce disease and insect resistant crops while growing faster and stronger.


the answer is C


Which of these is a rapidly occurring environmental change? A. Skovfølge

B. Tree growth

C. Degradation

D. Volcanic eruptions

Thank you for your help. I'll give the smartest one for the first answer



Its (D) volcanic eruption



D. Volcanic eruptions


Ok, logically, if you look at the answer I gave (Volcanic Eruption), there is a clear idea that it doesn't take time to happen. No, volcanic eruptions happen in a few hours and end up with big drastic changes within that time, which is much shorter than the other change options (tree growth, decomposition, forest succession).

I also took the test.

Which statements describe S waves? Tick ​​all that apply. They move from side to side.
They arrive after the P waves.
They travel through solids.
They travel through liquids.
They occur on the surface of the earth



The correct answers are "They move back and forth", "They arrive after P waves", and "They travel through solids".


S waves are one of two types of seismic waves, named after "secondary waves" because they are the second wave to arrive at an earthquake center after P waves (primary waves). S waves travel back and forth, so they are considered transverse waves. S waves travel through the body of solids, unlike other waves that travel on the surface of objects.

How is gene expression regulated? ›

Specifically, gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.

What are the major steps of gene expression quizlet? ›
