According to the Egyptian STEM biology syllabus, what is the exact scientific deduction regarding: Chargaff's Rules of DNA Base Pairing?
Adenine bonds with Guanine via three hydrogen bonds
In any double-stranded DNA molecule, the percentage of Adenine equals Thymine (%A = %T) and Guanine equals Cytosine (%G = %C), with total purines equaling pyrimidines (%A + %G = %T + %C = 50%)
Uracil replaces Thymine in the double helix of nuclear DNA
The percentage of %A + %T always equals 50% in all organisms
14.
According to the Egyptian STEM biology syllabus, what is the exact scientific deduction regarding: Transcription and Translation during Protein Synthesis?
Translation begins at the UAA stop codon
tRNA molecules contain codons identical to DNA triplets
RNA polymerase synthesizes mRNA from the antisense DNA template strand in the 5' to 3' direction, and translation occurs on ribosomes where tRNA anticodons bind mRNA codons
DNA polymerase transcribes mRNA in the cytoplasm
