Transcription - synthesis of RNA from DNA Transcription results in - mRNA RNA polymerase makes -mRNA mRNA - makes proteins RNA polymerase - binds to DNA Transcription factors (TFs) - A regulatory protein that binds to DNA and affects transcription of specific genes. Can wither activate or repress expression of genes Termination of transcription - RNA polymerase reaches a terminator sequence (Stop codon) and detaches from the template Translation - Process by which mRNA is decoded and a ...

BIOLOGY AQA AS 74011 PAPER 1 [WELL VERIFIED] • The human cell then makes a complementary strand to the HIV DNA. The complementary strand is made in the same way as a new complementary strand is made during semi-conservative replication of human DNA. Describe how the complementary strand of HIV DNA is made. - ANS---- there are complementary nucleotides/bases pair - DNA polymerase used - Nucleotides join together (to form new strand)/phosphodiester bonds form; Contrast the structures of ...

MCB4304 Exam 2 Final Questions & Answers 2024/2025 When trying to solve a protein structure, why is it necessary to grow protein crystals prior to X-ray-crystallography? - ANSWERSthe proteins must all be oriented in the same manner in the unit cell. The helix-turn-helix DNA binding motif is a feature exclusive to prokaryotes. - ANSWERSfalse Helix-turn-helix DNA binding motifs exclusively interact with DNA base pairs. - ANSWERSfalse DNA binding proteins can interact with the DNA str...

WGU Biochemistry Final Review 2024 With Complete Solutions Latest Guide A+. 1. The polymerase chain reaction is a tool used to study protein structure. True False - ANSWER-False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue - ANSWER-Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DN...
