The steps of protein synthesis

What do you think classifies an organism as living ?

viktelen [127]

Answer:

The seven taxonomic ranks classifies an organism as living. kingdom, phylum or division, class, order, family, genus, species.

Explanation:

These explain specific descriptions of what the organism might be instead of giving a broad generalization. If the suspected "organism" doesn't meet the criteria, it is not living and isn't an organism.

The prevention of expression of operons encoding substrate use pathways for substrates other than glucose when glucose is presen

adell [148]

Answer:

The answer is : Carbon catabolite repression

Explanation:

Carbon catabolite repression is a vital part of the global control system of the bacteria and other microorganisms. It allows the microorganisms to quickly adapt to the preferred energy and carbon source first. This is generally achieved by the inhibiting the synthesis of the enzymes that are involved in the catabolism of other carbon sources.

This effect was first shown to be initiated by glucose. Therefore, the carbon catabolite repression is also known as glucose effect.

Need a hypothesis for “How are proteins built from RNA”

Dima020 [189]

Hi!

Hypothesis:

<em>Proteins are built from the translation of messenger RNA (mRNA) molecules</em>

RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).

RNA is generated through transcription of the DNA molecule, resulting in a <em>complementary </em>molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA <em>(complementary with U instead of T)</em>

<h3><u>From RNA to Protein</u></h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon <em>UCA</em>, the tRNA will allocate a <em>Serine residue.</em>

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.

Hope this helps!

What part of the body does tuberculosis mainly affect?

kondor19780726 [428]

Answer:

TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine. A person with TB can die if they do not get treatment.

How did the asteroid that smashed into Yucatan, Mexico 66 million years ago kill so many organisms (including the non-avian dino

Bad White [126]

Explanation:

Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 66 million years a couple of things can happen:

Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.

The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.

Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.
