Homework Answers
Question 1: All are correct.
TBP recognizes 5’-TATAAA-3’. It is considered as a universal transcription factor. It is also a part of transcription factor (TF) IID and binds to consensus sequence (TATAAA).
Question 2: Made up of alternating phosphate and sugar groups.
Alternating units of phosphate and deoxyribose units form DNA backbone, while nitrogenous bases are packed inside the helix.
Due to time constraint, I am unable to answer all the questions now. Kindly repost rest of the questions separately or mention “answer all the questions”. As per the HOMEWORKLIB RULES, I am only supposed to answer the 1st question (in case of multiple questions) or first 4 questions (in case of multiple subparts). If you have any specific doubts, I can answer in the comments.
