HELP!! What are the steps from gene to protein? Label and describe each step.

1 answer:

5 0

DNA makes up genes. Transcription: The info stored in the gene's DNA is transcribed to RNA in the cell nucleus. The type of RNA that contains the info for making a protein is called messenger RNA, also known as mRNA. It carries out the information from the DNA, out of the nucleus, and into the cytoplasm. Translation: This happens in the cytoplasm. It is where the mRNA interacts with the ribosome, which "reads" the sequence of mRNA bases. Three bases make a codon, which usually codes for one particular amino acid, which is building blocks of proteins. Then, another type of RNA called transfer RNA, aka tRNA, assembles the protein by folding. This continues until the ribosome reaches a stop codon.

true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thor

faltersainse [42]

The thorax is a very vital and important organ in the human body.

It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.c

It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases.

When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases.

Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law.

Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.

Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

If 1/8 remains after 21 years, what is the half-life?

vagabundo [1.1K]

Half life formula

The number of unstable nuclei remaining after time t can be determined according to this equation:

N(t) = N(0) * 0.5^(t/T)

where:

N(t) is the remaining quantity of a substance after time t has elapsed.

N(0) is the initial quantity of this substance.

T is the half-life.

It is also possible to determine the remaining quantity of a substance using a few other parameters:

N(t) = N(0) * e^(-t/τ)

N(t) = N(0) * e^(-λt)

τ is the mean lifetime - the average amount of time a nucleus remains intact.

λ is the decay constant (rate of decay).

All three of the parameters characterizing a substance's radioactivity are related in the following way:

T = ln(2)/λ = ln(2)*τ

How to calculate the half life

Determine the initial amount of a substance. For example, N(0) = 2.5 kg.

Determine the final amount of a substance - for instance, N(t) = 2.1 kg.

Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.

Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.

If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.
