If you block histone deacetylase, what effect would you expect to see on transcriptional activity?.

Biology
1 answer:
Shalnov [3]2 years ago
8 0
Histone deacetylase is responsible for removing the acetyl group from the histone 3 lysine 9 residue. Remember that deacetylation is one step in converting euchromatin to heterochromatin. Because euchromatin is transcriptionally active (transcriptional machinery is able to reach gene of interest), and blocking histone deacetylase activity would result in an the DNA remaining as euchromatin, we would expect to see an increase in transcriptional activity.

So there’s your answer: An increase in transcriptional activity.

ivann1987 [24]

Answer:

A

Explanation:

Golgi apparatus, a membrane-bound organelle with cisternae, delivers proteins and lipids from the endoplasmic reticulum to where they are needed- such as for secretion outside the cell. Fused vesicles with proteins/lipids that pinch off from the <em>trans</em> end of the ER fuse with the <em>cis</em> end of the Golgi apparatus delivering the ‘cargo’. The proteins/lipids are then given post-translation modified and ‘marked’ for different deliveries. At the trans end of the Golgi apparatus, the vesicles pinch-off with the modified proteins and transported to their destination.

Answer: Ecosystem Services

Explanation: Simply put,Ecosystem services refer to all the benefits that man enjoys from his relationship with the ecosystem.Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provision,regulation and cultural services that directly affect people, and supporting services needed to maintain the other services. From the availability of adequate food and water, to disease regulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment.

We depend on nature for our survival – without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. Studies also show that people who spend time in nature tend to be happier than those that don’t. Being outdoor can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the compromise we are making between nature and industrial development.

Meiosis is called reduction division. When does the reduction in chromosome number occur?
aniked [119]

The reduction in chromosome number occurs during <u>meiosis I.</u>

Chromosomes are long molecules of DNA that contain some or all of an organism's genetic material. In most chromosomes, very long, thin strands of DNA are coated with packaging proteins. In eukaryotic cells, the histones are the most important of these proteins.

Within the nucleus of all cells, DNA molecules are packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly wrapped many times around proteins called histones that support its structure.

Another type of cell division, meiosis, ensures that humans have the same number of chromosomes from generation to generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs.
