Why is it important that transcription and translation take place exaclty every time?

Question by armstrong_terri: Why is it important that transcription and translation take place exaclty every time?
Also what might be the effect genotypically and phenotypically if “mutations” occur? What is transcription and translation?

Best answer:

Answer by Deeps
TRANSCRIPTION is the process of synthesis of m-RNA from a single strand of parental DNA.
TRANSLATION is the process of synthesis of polypeptides(proteins) from amino-acids with the help of m-RNA,t-RNA , ribosomes etc.
Mutations are the IRREVERSIBLE,HERITABLE changes occouring in the genome(DNA)of a person.so,GENOTYPICALLY,the DNA changes.While PHENOTYPICALLY,the appearance of the person might or might not change depending on where on the DNA the mutation occours.

it is quite simple
transcription is like someone gave you a piece of paper that you need but he also needs it so you copy it
DNA has written down everything you need so it is coppied on the mRNA
translation is that paper you coppied is in some foreign language you don`t understand so you need someone to translate and then you know what it says
mRNA has codes on it some crazy letters(ACGT) repeating in some order you have no idea what these letters are 3 of them code one aminoacid and aminoacids make proteines which make a lot of you
if an error occurs it ain`t good down syndrom is a muttation or being albino is muttation
hope it helped

If the two processes don’t copy the templates exactly everytime, that leads to mutations in the following strand. If there are mutations, that leads to different properties of the proteins made in translation. Depending on the mutation, this can have either a beneficial or very adverse effect, or even none at all, depending on where the mutation is, and if different amino acids are used.

For example, sickle cell anemia is caused by a single mutation. Genotypically, one nucleotide is substituted for another, leading to a different amino acid. Phenotypically, this different amino acid causes different bonding patterns in the hemoglobin protein, causing red blood cells to sickle.
