5’ ttagcg 3’ which of the following nucleotide base sequences complements the section of dna modeled above? 5’ utcgca 3’ 3’ aatcgc 5’ 5’ gcgatt 3’ 5’ ttucgc 3’

The given DNA sequence is 5’ TTAGCG 3’ . According to Chargaff's rules state that Adenine is always pairs with thymine and guanine is always pair with cytosine. So in the given sequence 5’ TTAGCG 3’ the nucleotide base sequences complements the section of DNA is 3’ AATCGC 5’. Hence, option 2 is correct ,because it follows chargaff's rules and complementry strand always read in 3' to 5' as DNA sequence present in 5' to 3'.

d. changes in climate and historical records

hope this
