Question

The RNA primer is used in

• A. translation
• B. replication
• C. conjugation
• D. transformation

Answer 1

The Correct Option is B

The RNA primer is used in replication of DNA. The new strands of DNA are formed in the $5 \to 2$ direction from the $3 \to 5$ template DNA by the addition of deoxyribonucleotides to the $7$ end of RNA primer. Translation is the process in living cells in which the genetic information encoded in nRNA in the form of a sequence of nucleotide triplets is translated into a sequence of amino acids in a polypeptide chain. It takes place on ribosomes in the cell cytoplasm. Conjugation is the fusion of two reproductive cells, particularly, when these are both of the same size. It is a form of sexual reproduction in some algae, some bacteria and ciliate protozoans. Transformation is a permanent heritable change in a cell, particularly a bacterial cell, that occurs as a result of its acquiring foreign DNA.

Answer 2

A DNA primer is not required to carry out a PCR reaction. RNA primers should be used in PCR instead of DNA primers due to their unavailability and absence. The RNA primers are complementary to the cellular DNA are synthesized by the DNA Primase enzyme, which is actually RNA polymerase similar to mRNA.
Let's now choose a solution from the available options:
Translation: It is described as the procedure through which amino acids are created from RNA. The translation is, in other words, the polymerization of amino acids to create a polypeptide chain. The nucleotides found in the messenger mRNA's messenger sequence determine the order and sequence of the amino acids.
Replication is the process of creating a new strand of DNA from an existing one, sometimes referred to as the parental or template DNA. A key component of this procedure is the RNA primer.
Conjugation: A key technique in DNA recombination that interacts with transformation and transduction is conjugation.
Transferring DNA material from one bacterial cell to another via transformation or transduction is the two main methods that may be used.

 

Answer 3

Organisms with only one cell have very straightforward structures. As a result, they frequently reproduce in an asexual manner. It is so because unicellular organisms may rapidly reproduce through asexual reproduction. First, a description of binary fission in amoeba and budding in yeast.
Male and female gametes must fuse during sexual reproduction, whereas cell division occurs during asexual reproduction.
Humans, animals, and decomposers are heterotrophic creatures that may reproduce asexually or sexually. For instance, in bacteria, sexual reproduction takes place by conjugation, and asexual reproduction takes place through binary fission.
Uninucleate organisms, such as Ulva (algae), may reproduce sexually and asexually by fusing gametes.
