What if the C-G base pair in the DNA molecules substituted by an A-T base pair?

This really depends on where the nucleotides were in an entire DNA strand. In truth, an entire DNA pair is not substituted or mutated - the mutations occur on one DNA strand and cause problems when the matching strand is being created.
So, with the example you gave, an adenine (A) could have been placed where the cytosine (C) should have been. If the same amino acid was created as a result, even with the change, there would be no effect in the end. If a similar amino acid was created with the change, the effect would be minor.
A large problem may occur if the base change resulted in a completely different amino acid that would ultimately function differently. Finally, a potentially deadly result could occur if the new nucleotide signalled the production of a stop codon, or an amino acid that would stop the entire process. The DNA strands would be incomplete and could be harmful to the organism.

In DNA which is harder to break the adenine-thymine base pair or the guanine-cytosice base pair Why?
thymine
What nitrogen base can pair with adenine?
What is mean by the term base pairing how is base pairing involved in DNA replication?
i am not sure
What makes up dna molecules?
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
Copy and complete the events chain concept map of DNA synthesis?
step1: enzyme separates DNA sides. step2: new bases pair with bases on original DNA. step3: two new identical DNA molecules are produced.
Is thymine a DNA base pair?
It is not a DNA base pair itself, it is a DNA nucleotide base. It does however, form a base pair when bonded with adenine.
What 3 molecules are involved in transcription?
Many molecules preform transcription. From the DNA required as a template to the mRNA and tRNA and the protein (ribosomes).The enzyme (made of molecules) that transcribes DNA into RNA is transcriptase.Because I don't fully understand your question, enzymes are not usually referred to as molecules you may be asking about the base pairs for RNA which are referred to as molecules of adenine (A) which forms a base pair with uracil (U) and guanine (G) which forms a base pair with cytosine (C).
In DNA which what are the complamentary base pair?
In DNA,adenine----------thyminecytosine----------guanine
In DNA which is harder to break the adenine-thymine base pair or the guanine-cytosice base pair Why?
thymine
How much phosphate molecules are inside the DNA?
There are an estimated 3 billion base pairs inside of human DNA. Each base contains one phosphate group so each base pair would contain two. Ergo, there would be an estimated 6 billion phosphate groups in human DNA.
Which DNA base always pair with cytosine?
Guanine
What base does messenger RNA always pair with?
DNA
What are the arrangements of two base molecules in DNA?
nothing
What base in RNA pair with adenine?
Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.
What does the base in DNA molecule pair with?
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent
In a DNA molecule what base pair could normally be composed of?
iron
What do thymine mean?
Thymine is the complementary base pair for adenine in DNA.
