There are three types of RNA involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribisomal RNA (rRNA). All three of these nucleic acids work together to produce a protein. The mRNA takes the genetic instructions from the nucleus to the cytoplasm, where the ribosomes are located.
Answer:
The Genotype of an organism determines the genetic characteristics of an individual.
If a father produces sperm that carry only 't' alleles, the his genotype will be 'tt' or hom.ozygous genotype.
Hom.ozygous genotype contains the same type of genes responsible for a particular phenotype.
Hence, the correct answer is 'tt' or hom.ozygous genotype.
Cellular immunity kills pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.
<h3>What is the difference between Cellular and Humoral immunity?</h3>
The main difference between humoral and cell-mediated immunity is that humoral immunity produces antigen-specific antibodies, whereas cell-mediated immunity does not produce antigen-specific antibodies. The cellular immunity destroys pathogens and harm microbes that are present inside the cell, whereas humoral immunity kills pathogens outside the cell.
So we can conclude that cellular immunity kills pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.

Answer: Peroxisome
Explanation:
A peroxisome is a membrane-bound organelle usually found in the cytoplasm of almost all eukaryotic cells. It is an oxidative organelle.
Eukaryotes are comprised of one or more cells that contain peroxisomes. The organelles were first discovered by the Belgian scientist Christian de Duve, who was same person that discovered lysosomes.
Peroxisomes contain a variety of enzymes, which primarily function together to get rid of toxic substances in the cell, and in particular, hydrogen peroxide which a common byproduct of cellular metabolism. These organelles contain enzymes that convert the hydrogen peroxide to water, making it remain safe in order to be released back into the cell. Some types of peroxisomes, such as those in liver cells, detoxify alcohol and several other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (known as oxidation). Other perixosomes are more important for their ability to initiate the production of phospholipids, which are typically used in the formation of membranes.
