Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?

oee [108]

Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.

mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to the ribosomes of a cell, which are in charge of reading the code, one codon at a time, and chaining together the corresponding amino acids.

In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome sep

Ipatiy [6.2K]

1. two copies of the duplicated chromosome are attached at their centromeres before separating

2. chromosomes replicate before cell division

3. chromosome separation begins at the origin of replication on DNA

4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation

5. replicated chromosomes separate by attaching to some other structural feature of the cell

Explanation:

In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.

Eukaryotes

1. Option-4 as the nuclear envelope is present in eukaryotes only.

2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.

Bacteria

1. Option-3 as DNA replication process separates the strand of the DNA.

Both

1. Option-5 as the chromosomes separate by other structures like microtubules

2. Option-2 as genetic material to be passed on to the generation must be replicated.
