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

The diagram shows three steps in the carbon cycle.
Bumek [7]

Answer:

A. Cellular respiration

C. Photosynthesis

Explanation:

There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.
