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.
The geneticmcode would be different For example: Its like a sentence...if you replace a word with another word that isnt alike at all, then there could be errors and mutations could happen
thymine
i am not sure
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
step1: enzyme separates DNA sides. step2: new bases pair with bases on original DNA. step3: two new identical DNA molecules are produced.
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.
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,adenine----------thyminecytosine----------guanine
thymine
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.
Guanine
DNA
nothing
Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.
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
iron
Thymine is the complementary base pair for adenine in DNA.
