Swamps or maybe those in the desert. In swamps, the soil is too loose for animals to burrow without it caving in. In deserts, since the climate "rising" its getting to hot and dry for animals to burrow without the sand caving in when an animal walks above it.
Answer:
mRNA or messenger RNA goes to ribosomes to dictate the genetic information that it contains .
Explanation:
Ribosomes act as work benches during protein biosynthesis.mRNA also called messenger RNA binds with the smaller subunit of ribosome at the time of translation.
The bound subunit of ribosome reads the genetic information as codons containing three concecuetive nucleotides present in mRNA thus helping tRNA to bring the particular amino acid specific for that codon at the A site or attachment site of ribosome.
Thereafter ribosome moves to the next codon to bring another amino acid and so forth.
Thus mRNA helps ribosome to brings the amino acids at the translation site.
