The molecules that brings amino acids to the ribosomes are the tRNA molecules.
Hope this helped <3
Answer:
a. GC->CG in the protein coding region on a gene. - Base substitution
b. GC->TA in a GAA glutamate codon - Base substitution
c. Loss of three bases GAA for a glutamate codon - Deletion
d. GC->CG in a tRNA gene - Insertion
e. GC->AT in the ribsome binding site of a mRNA - Frameshift mutation
Explanation:
DNA mutation occurs as a result of a change in the gene sequence of the protein being coded by the genes. Several causes of mutation involve radiation, heavy metal exposure, etc. There are different types of gene mutation. These include a deletion where the bases are deleted. Another one is the insertion where a base is inserted into the sequence. This lengthens the base sequence of the gene. Another mutation is the base mutation -this can take place as a result of inversion. Inversion reverses the order of the bases in a sequence like this: normal CGGA → AGGC
These mutations result in disorder e'g Downs syndrome, Puckingtons disease, Cystic fibrosis etc.
I’m going home now I just want to let you know I have to leave at lunch to
Zwitterion
Zwitterion also known as dipolar
ion refers to a substance that has at least one positive and one negative
electrical charge at different locations and the net charge of the entire
molecule is zero. Examples of zwitterions are amino acids.
E. very small atoms
fusion reaction in which two atoms of hydrogen combine together or fuse to form an atom of helium
