[Lucid_dreams]

1. bases
2. The synthesis of enzymes would stop
3. DNA base sequence

[sergio g]

1) Nitrogenous Bases (a)
A represents adenine
T represents Thymine
C represents Cytosine
G represents Guanine
These nitrogen bases are the makeup for DNA. Their sequences are unique to each individual person

2) Enzyme Synthesis would not occur (b)
Ribosomes hold a very specific function in a cell. Amino acids are constantly floating in the cytoplasm of a cell. The ribosomes work as people on a convener belt which use mRNA as sequences to produce specific enzymes.

3) DNA base sequences (c)
DNA's nitrogen base order is vital to the individuality of a person. I am sure you have heard of DNA fingerprinting? it is when police keep a copy of someone's DNA on file so as to always be able to identify an individual. DNA base sequence is individualistic(identical twins have the same base sequences ergo they look identical).


Hope this helps. I know how difficult Biology can be to master.
