Is the binding of a transcription factor to its dna recognition sequence necessary and sufficient for an initiation of transcrip
hram777 [196]

Transcription factors are necessary for an initiation of transcription at a regulated gene but not sufficient.

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 Transcription factors can enhance the interaction between RNA polymerase and a DNA sequence- promoter, encouraging the expression of the gene. Such transcription factors are called activators. Otherwise, when the gene expression is inhibited, factors are called repressors and they bind to sequence –operator.

• 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

Which of the following are examples of positive feedback loops? (Choose all that apply)
aleksley [76]

The examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
  • Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.

  • The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.

  • Also, the clotting of blood causes the stoppage of blood flow.

Therefore, the examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

Human digestion of food begins in the _______, where the enzyme _____ breaks down a small amount of starch. Mouth; amylase stoma
Alexandra [31]

The digestion of the food in humans begins in the mouth. In the mouth, the salivary amylase enzyme digests and breaks down a small amount of the starch present in the food. The digestion process begins right in the mouth. and continues till the intestine. The carbohydrates (starch) are the ones whose digestion starts in the mouth.

Hence, the blanks can be filled with 'mouth and amylase' respectively.
