mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.
A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>.
Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.
The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence.
<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).
Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
