What are real life examples of ribosomes

DNA holds the plan of an organism and life, but ribosomes are the factories where this plan is translated into proteins that will make up the muscles, transport the substances in or between cells, send and receive signals, trigger chemical reactions, etc.

For the examples, you can take an example of an assembly plant according to your imagination (factories has vehicles that assemble the parts, a meat factory making sausages, factories of multimedia devices ...).

Everything starts at the DNA level. The DNA segment that carries the genetic code of a given protein is copied to a single-stranded messenger ribonucleic acid (mRNA). The mRNA attaches to a ribosome, which moves throughout the mRNA molecule by "reading" the genetic code. Each block of three "letters" corresponds to the genetic code of one of the amino acids used to make the proteins. Molecules of another type of RNA, the RNA transfer (tRNA), recognize this genetic code and provide the ribosome with the corresponding amino acid. As the ribosome travels along the mRNA, it links the amino acids into a chain, gradually making the protein.

A carpenters work bench. Any workbench because the ribosome is the " workbench "upon which proteins are assembled.

In the plasma, the quantity of oxygen in solution is ________.

zysi [14]

Answer:

D. only about 1.5% of the oxygen carried in dissolved form is correct answer.

Explanation:

Plasma is a component of blood, it has many functions in our body like fighting against diseases, clotting the blood.

In the plasma, the quantity of oxygen in solution is about 1.5% of the oxygen carried in dissolved form and 98.5% of the oxygen is bound to hemoglobin.

Thus option (D) only about 1.5% of the oxygen carried in dissolved form is correct.

In bacteria, the antibiotic chloramphenicol prevents amino acids from bonding. The MOST likely reason that bacteria die from tre

iris [78.8K]

Answer& explanation:

The mechanism of action of chloramphenicol can be explained as follows:

Chloramphenicol binds to the 50S subunit of the ribosome, inhibiting the protein synthesis of the bacteria, thus having bacteriostatic action (inhibiting the growth of bacteria, preventing their proliferation).

In addition, chloramphenicol can be bactericidal (destroys bacteria) when in high concentrations, or when used against highly sensitive microorganisms, such as Haemophilus influenzae and Streptococcus pneumoniae. The mechanism of action for these bacteria, however, is not yet elucidated.

Determine predicted phenotype ratio in children of a woman who is dihybrid for right handed and free earlobes and a man who is l

gavmur [86]

Answer:

All the offspring will have genotype RrEe and will be right handed and have attached earlobes

Explanation:

Let the dominant allele for right hand trait be "R" and the recessive left hand trait allele is "r"

Allele for attached earlobes trait is "E" and free earlobes trait is "e"

Genotype of woman who is right handed and has free earlobes - RRee

Genotype of man who is left handed with attached ear lobe - rrEE

The genotype of offspring would be RrEe

All the offspring will have genotype RrEe and will be right handed and have attached earlobes
