Why does the cell need both mRNA and tRNA in order to synthesize a protein like hemoglobin?

DNA and RNA (m and t) are made of nucleotides. Proteins like hemoglobin are composed of amino acids.
The mRNA specifies the sequence information needed for making the hemoglobin protein. This information is a direct and temporary copy of information contained on a gene on DNA.
The tRNA is a separate molecule the carries an amino acid on it. It is like a mediator. It has sequence that matches to a small part of the sequence being specified by the mRNA. When the tRNA moves into the right position on the mRNA, the amino acid detaches from the tRNA and is added to the growing protein or polypeptide chain.

How animals and plants get protein?
Pretty much any living organism produces proteins since proteins are necessary for life. This includes everything from plants to fungi to microbes to cells. Viruses cannot produce proteins in and of themselves since they need their host's ribosomes to make their protein.
Is a protein different from protein?
no they are both the same
How do rough and smooth er compare structurally and functionally?
same structure and both synthesize something
Why does a virus not have both DNA and RNA?
Because it doesn't use it's DNA or RNA to function, it uses it to inject into a cell and switch the cell's instructions to its own so the cell will make more viruses. Cells have DNA and RNA to tell the cell what to do, but viruses just do it naturally. Viruses have no use for both.
How do cells replace the energy-rich ATP that is destroyed in energy-coupled reactions?
Both chloroplasts use light energy to synthesize ATP and mitochondria synthesize ATP using energy that's realeased by oxidizing sugars and fats.
Where do hemoglobin synthesize?
at the bone marrow and liver and it occurs in both the cell's mitochondria and cytosol
What complex protein can carry both carbon dioxide and oxygen in the circulatory system?
Hemoglobin
Do both plants and animal cells have ribosomes?
Yes they both do.
What are the two food values needed for the formation of haemoglobin?
Hemoglobin is a protein and it has an iron ion that can attract an oxygen molecule to it. Both proteins and iron can be found in food.
What change occurs in hemoglobin upon respiration?
The iron molecule (that's the hemo- in hemoglobin) gains and/or loses an oxygen molecule. The protein part (that's the globin) changes shape a bit. Both changes are very reversible and requires little energy.
What a hemoglobin AIC lab test tells the health care provider?
A hemoglobin A1C test tell your health care provider the percentage of your blood protein that is covered in sugar. It is used to diagnose both Type 1 and Type 2 Diabetes.
Which of the following is a characteristic of both hemoglobin and hemocyanin?
The two molecules transport oxygen in cells, hemoglobin being the iron-based protein found in the blood of mammals, while hemocyanin is a copper-based compound found in some invertebrates, including mollusks and some crustaceans.
Is human hemoglobin different from a mouse hemoglobin?
practically no difference. In both the hemoglobin has the same job, bonding with oxygen.
What is hemogiobin?
Hemoglobin is a protein carried by red blood cells to pick up oxygen in the lungs and deliver it to the peripheral tissues and maintain the viability of cells. it is made from two similar proteins that "stick together". these proteins must both be present for the hemoglobin to pick up and release oxygen. One of the proteins is called alpha, the other beta. Before birth, the beta protein is not expressed. A hemoglobin protein found only during fetal development, called gamma, substitutes up until birth. HemogLobin is the part of red blood cells that picks up oxygen in the lungs and releases it in your muscles, or wherever else it is needed.
How animals and plants get protein?

What are the similarities between collagen and hemoglobin?
It is a protein They have both quartenary structures haemogalobin has 4 polypeptide chains with a prosthetic heam group and Collagen 3 polypeptide chains wound around each other by hydrogen bonds.
Which vitamin is important for hemoglobin?
Hemoglobin is a protein in red blood cells that carries oxygen from the respiratory organs to the rest of the body by way of the blood. When someone is lacking in hemoglobin, the condition is known as anemia. Iron is an important vitamin for hemoglobin production, as it increases resistance to stress and disease and improves blood quality. Vitamin C supports the absorption of iron, so it is also necessary to have enough vitamin C for healthy blood.
