What are the steps of translation that lead to gene expression

Biology
1 answer:
vampirchik [111]3 years ago
8 0
1. Initiation: ribosome assembles itself around mRNA and first tRNA attaches at start codon

2. Elongation: tRNA transfers amino acid to next tRNA, amino acids attach, and ribosome shifts by one codon so first tRNA detaches. This continues and forms an amino acid chain.

3. Termination: when tRNA encounters a stop codon, the process ends and polypeptide chain is folded into final form.

tructures used in recombinant DNA technology to carry the DNA from the cells of one species to the cells of another species are
Kobotan [32]

The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.

When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.

Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).

The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.

Mole ends=2x(moles DNA)x number of restriction sites.

The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.

Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].

What are the three functions of a cell membrane? I will give Brainliest to the best answer!
____ [38]
(1) they keep toxic substances out of the cell;
(2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment;
(3) they separate vital but incompatible metabolic processes conducted within organelles.

Which way will the water the water tend to move (in terms of sugar concentration)?
Valentin [98]
<span> water has a tendency to move across a membrane from a lower osmolarity to a higher osmolarity.
</span>
<span>When red blood cells are placed in distilled water, which is hypotonic compared to the solution contained within the cells' membranes, the distilled water will diffuse into the red blood cells and cause them to burst.</span>
