Transcription factors are regulatory proteins in eukaryotes that control the initiation of transcription by binding to specific DNA sequences near genes and either activating or repressing their transcription. This binding helps regulate the expression of genes by influencing the binding of RNA polymerase to the promoter region of a gene.

What major enzyme is involved in transcription?
A u g
What mechanisms exerts gene control by suppressing transcription in eukaryote?
Gene control by suppression of transcription in eukaryotes can be achieved through various mechanisms such as DNA methylation, histone modification, and the action of transcriptional repressors. These mechanisms can block access of transcription factors to the gene promoter region, leading to reduced gene expression. Additionally, chromatin remodeling complexes can be involved in creating repressive chromatin structures that prevent transcriptional machinery from binding to DNA.
What percentage of eukaryotic DNA transcribes protein?
Only a small percentage of eukaryotic DNA, estimated to be around 1-2%, is directly involved in transcribing protein-coding genes. The rest of the DNA is involved in various regulatory functions, such as controlling gene expression and maintaining genome structure.
What nucleic acids are involved in transcription?
Deoxyribose nucleic acid, transcribed into, Ribose nucleic acid.
What is initiation in transcription?
Initiation in transcription is the beginning stage where RNA polymerase binds to the promoter region of a gene and starts unwinding a section of DNA to synthesize a complementary RNA molecule. This process is crucial for the initiation of gene expression and the production of mRNA.
Is tRNA involved in transcription?
tRNA is not directly involved in transcription. tRNA is responsible for transferring amino acids to the ribosome during translation, where it helps in the assembly of the polypeptide chain based on the mRNA sequence. Transcription is the process of synthesizing mRNA from DNA.
What two nucleic acids are involved in transcription?
Transcription involves the synthesis of RNA from a DNA template. The two nucleic acids involved are DNA, which serves as the template for RNA synthesis, and RNA, which is the product of transcription.
Which is the protein involved in promoter recognition in eukaryotes?
TFIID
Which protein is involved in promoter recognition in eukaryotes?
In eukaryotes, the TATA-binding protein (TBP) is involved in promoter recognition. TBP is a subunit of the transcription factor II D (TFIID) complex, which binds to the TATA box within the promoter region of genes and helps initiate transcription.
Are troponin and tropomyosin contractile or regulatory proteins?
Troponin is a regulatory protein while tropomyosin is a contractile protein. Troponin is involved in regulating muscle contraction by controlling the interaction between actin and myosin. Tropomyosin works in conjunction with troponin to regulate the binding of myosin to actin during muscle contraction.

What percentage of eukaryotic DNA transcribes protein?
Only a small percentage of eukaryotic DNA, estimated to be around 1-2%, is directly involved in transcribing protein-coding genes. The rest of the DNA is involved in various regulatory functions, such as controlling gene expression and maintaining genome structure.
Where is the failure of the brains temperature regulatory center involved?
The failure of the brain's temperature regulatory center can lead to conditions like heatstroke or hypothermia, where the body is unable to properly regulate its temperature. This can result in serious health complications or even be life-threatening if not addressed promptly.
What is the mitochodria primarily involved in in the eukaryotes?
site of energy (ATP) production
What governing body is not involved with approving testing and controlling a new drugs?
this governing body is NOT involved with approving, testing, and controlling new drugs
