how does the ribosome read the mRNA?
Answer:
A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).

fertile feeding grounds. They migrate to the north in summer months.
The reindeer migrate from north to south in the summer months to reach
more fertile feeding grounds. They migrate to the north in winter months.
The reindeer populations migrate to an intermediate location in Norway to
mate and then diverge to the northernmost and southernmost regions to
avoid competition for food.
There are two species of reindeer in Norway. The northernmost species
reproduces in the winter, causing an increase in population size. The
southernmost species reproduces in the summer, causing an increase in
population size.

It is now A G C A A C C C G T C T T G G T C G T T G G G C A G A A C C Use your knowledge of mutation and protein synthesis to answer the following questions. What mutation has occurred
The mutation that has occurred is substitution mutation.
Mutation is defined as the random changes in deoxyribonucleic acid (DNA) that alter genetic information, and so can introduce new characteristics.
Mutation can occur in because of the following reasons stated below:
When exposed to environment saturated with ultraviolet light, it can cause cell mutation; andWhen exposed to certain chemical such as free radicals.A typical example of mutation that occurs in DNA is the substitution mutation.
Protein synthesis is the process used by cells to produce usable specific proteins as directed by the DNA.
The base sequence in DNA determines the sequence of amino acid in peptide.
Substitution mutation occurs when one base is incorrectly replaced in the complementary strand of a DNA.
From the DNA base sequence given,
Cytosine replaced Thymine; andGuanine replaced Adenine.This replacement that occurred will lead to abnormal protein synthesis.
