1. Describe the structure and function of each of the three types of RNA.
Ket [755]

Answer:

1.

mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.

tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.

rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.

2.

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.

3.

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.

GaryK [48]
<h2>The correct answer is: Mutualism.</h2>

Explanation:

  • Mutualism can be defined as a type of symbiotic relationship.
  • Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
  • Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
  • In the given question, some micro-organisms survive in the digestive tract of the cattle.
  • These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
  • On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.
