The double helix structure of DNA, transcription and translation all depend on b

Question

The double helix structure of DNA, transcription and translation all depend on base-pairing rules that match each type of nucleotide in DNA or RNA with another nucleotide which has a complementary base. The base-pairing rules are slightly different in each case because the base T in DNA is replaced by U in RNA. Complete the following tables to describe these base-pairing rules Basc Rules in DNA Double Helix Base in one strand of DNA lementary base in the other strand of DNA Base- Rules in Transcription Base in DNA of a gene Compl ATCG lementary base in mRNA Base Rules in Translation Base in mRNA codon Complementary base in anti-codon 3. The first row of the table gives the nucleotide sequence in the non-template strand of a hypothetical mini-gene. (unrealistically small)_ Use the base-pairing rules to complete the table and do not forget start and stop codons Non-template strand of DNA Template strand of DNA Transcription of template strand of DNA Rewrite the mRNA molecule as a set of Anti-codons in the tRNA molecules which will CATGGTATGAGCT uces mRNA let codons in the correct reading frame bring the correct amino acids for translation 4. Which strand of DNA has the same nucleotide sequence as mRNA (taking into account that T in DNA is the equivalent of U in mRNA)?
