How does embryonic development and cell differentiation in

Biology
1 answer:
Ira Lisetskai [31]3 years ago
7 0
Mammals do not have a rigid cell differentiation pattern and cell count like the organism C elegans. Embryonic differentiation is the process of development during which embryonic cells specialize and diverse tissue structures arise.The differentiation of cells during embryogenesis is the key to cell, tissue, organ and organism identity. Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.

Given a sequencing reaction length of approximately 500 successive nucleotides, what is the absolute minimum number of sequencin
KengaRu [80]

Answer:

6.4 million

Explanation:

The human genome contains 3.2 billion bases (nucleotides).

Each reaction can sequence a read length of 500 nucleotides. We are excluding overlaps, and redundant sequences (which in reality would always happen when performing sequencing). Therefore, the minimum number of sequencing reactions is the total number of nucleotides in the genome divided by the length of read 3.2 billion ÷ 500 = <u>6.4 million</u>

Which is an example of visual data with regard to computer crime
AleksandrR [38]

"Image" is an example of visual data with regard to computer crime.

<u>Explanation:</u>

An act committed by a skilled or professional user of computers, also named as hacker who secretly browses or steals private information from a company or individual's system therefore this whole process is known as "computer crime".

Image is one of the best source or evidence in the form of visual data with respect to computer crime. Because many details can be collected or fetched out just from visual figures or pictures. It can contain codes, relatable links or some factors which can be helpful for targeting culprit.

The Krebs cycle involves the aerobic breakdown of glucose for energy. In the first reaction of the Krebs Cycle, the enzyme Aconi
Travka [436]

Answer:

The reaction is at equilibrium

Explanation:

The Krebs cycle is an aerobic pathway because the final electron acceptor required is oxygen.

The most common situation leading to a disruption in the function of Krebs cycle is the lack of oxygen to accept electrons in the electron transport chain.  

The conversion of citrate to isocitrate (isomerization), is catalyzed by the enzyme, aconitase (also known as aconitate hydratase). The hydroxyl (alcohol) group of citrate is moved to an adjacent carbon so that it can be oxidized to form a keto group.

This reaction involves generation of an enzyme-­bound intermediate, cis­aconitate. At equilibrium, there exists 90% citrate, 3% cis­aconitate, and 7% isocitrate; hence the equilibrium of aconitase lies toward citrate formation.

Although the aconitase reaction does not require cofactors, it requires ferrous (Fe2+) iron in its catalytic mechanism. This Fe2+ is involved in an iron–sulfur center, which is an essential component in the hydratase activity of aconitase.    

According to Gibb's free energy:

ΔG = 0 - Reaction at equilibrium.

ΔG > 0 - non-spontaneous reaction.

ΔG < 0 - spontaneous reaction.
