What's so the "Central dogma" or sequence of information flow in Turing genes into proteins?

1 answer:

8 0

Basically it involves translations:
Once you have your mRNA (which now only has exons) it then binds with rRNA (ribosomal RNA)
It reads a start codon, and then the tRNA reads a complimentary anticodon which codes for a specific amino acid.
Essentially the amino acids then interact elongate, and then you have a long chain of amino acids (primary structure of a protein)

Then there is a lot of folding, di-sulfide bridges and other interaction that then make the amino acids into a protein like haemoglobin (red blood cell)

(b) The antibiotic streptomycin inhibits protein synthesis in bacteria. If this antibiotic is added to a culture of animal cells

mixas84 [53]

Answer:

Mitochondrial ribosomes are similar to the prokaryotic ribosomes since mitochondria evolved by endosymbiosis. So, antibiotics can affect protein synthesis in mitochondria.

Explanation:

Streptomycin is an antibiotic that controls bacterial growth by binding to the small ribosomal subunit (the 30S) of bacteria. Thereby, this antibiotic interferes with protein synthesis and causes misreading of mRNA. Mitochondria were evolved when an anaerobic prokaryote engulfed an aerobic prokaryote which in turn became symbiotic later and lost the ability to live freely.

The ribosomes of mitochondria are similar to the bacterial ribosomes and are inhibited by the presence of streptomycin. Therefore, streptomycin was directly able to inhibit the protein synthesis in mitochondria while not affecting the same process in the cytosol of the cell.

Can someone help me write a five paragraph about a career in energy. You can choose either 1 option. Here's a list. (1) - Fossil

Over [174]

Answer:

5) Solor energy

Explanation:

Its the Most convenient one sense others you have to be in a specific place for it to work and the only bad thing about Solar energy is that if it's blocked by the sun it dosent work nuclear energy is unconvinient for the environment

Drag each label to the appropriate position to identify whether the given reaction occurs in glycolysis, the CAC, or the ETC Gly

Deffense [45]

Answer:

Establishment of a chemiosmotic gradient in the intermembrane space -> ETC

Conversion of G6P to fructose 1,6-diphosphate -> GLYCOLYSIS

ATP synthase activity -> ETC

Oxidation of NADH at enzyme complex1 -> ETC

Conversion of malic acid to oxaloacetic acid -> CAC

Conversion of acetyl-CoA to acetic acid -> CAC

Conversion of PGAL to pyruvic acid -> GLYCOLISIS

Conversion of glucose to G6P -> GLYCOLYSIS

Conversion of citric acid to isocitric acid -> CAC

Explanation:

There are three boxes of three different cycles

Glycolysis: Here, the cell convert glucose to piruvic acid

Citric Acid cycle (CAC): Here the cell oxydates Acetil CoA to generate energy in form of ATP

Electron transport chain (ETC): Here the cell produced ATP from the NADH and the FADH of glycolysis and CAC

What is cell biology

Anna [14]

Answer:

Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function and behavior of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several techniques such as cell culture, various types of microscopy, and cell fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how cells function, ultimately giving insight into understanding larger organisms. Knowing the components of cells and how cells work is fundamental to all biological sciences while also being essential for research in biomedical fields such as cancer, and other diseases. Research in cell biology is interconnected to other fields such as genetics, molecular genetics, biochemistry, molecular biology, medical microbiology, immunology, and cytochemistry.
