DNA-binding proteins influence the ability of RNA polymerase to initiate transcription of a gene.
Dicer processes and cleaves double-stranded RNA to produce 21- to 25- nucleotide-long sequences.
A cactus spine and a pea tendril illustrate homoplasy because both are modified leaves.
A. DNA‑binding proteins influence the ability of RNA polymerase to initiate transcription of a gene.
C. acetylation of histones by acetyltransferase; represses transcription
C. a complex of DNA polymerase, transcription factors, and other transcription proteins
D. DNA must be unwound from histone proteins before transcription of a gene takes place.
E. The basal transcription apparatus will repress transcription without them.
A. They can bind near an activator site and prevent activator contact with the basal transcription apparatus.
B. The basal transcription apparatus can only produce minimal levels of transcription without them.
