Over [174]

The correct answer is: b. It is free to bind to another promoter and begin transcription

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex.

RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.

First, drag labels to targets (a) and (b) to indicate whether these environments are hydrophilic or hydrophobic. 2.next, drag th

goldenfox [79]

Attached is the image respective of the question.

First, both the extracellular fluid and the cytoplasm are hydrophilic. The phosphate head of the phospholipid is hydrophilic hence it either faces the extracellular fluid and the cytoplasm. The lipid tail of the phospholipid is hydrophobic hence it is confined in the middle of the plasma membrane. Both cytoplasmic and the extracellular fluid ends of the transmembrane protein are hydrophilic and the middle part of the transmembrane protein is hydrophobic.

Most receptor proteins are embedded in the __________ of the cell membrane.

Naddik [55]

The appropriate response is lipid bilayer. The lipid bilayer is a widespread segment of all cell films. Its part is basic since its basic segments give the obstruction that denotes the limits of a cell.

I hope the answer will help you.
