Approximately how many proteins in the human body are estimated to function as transcription factors?

Around 2000 proteins are involved in the regulation of genes in the developing cell in a human body, though there is an estimated 2600 DNA binding proteins, but only around the 2000 is required to account for regulating all the genes in each of our genome during development. its about 10% of the total protein information we have in our genes because the human genome contains information to approx. 25000 proteins.

What is the primary function of a transcription factor?
To ensure that a gene is used at the right time and that proteins are made in the right amounts.
How would transcription errors as DNA is copied into RNA affect the proteins that are produced?
The proteins would have the wrong shape, would be made of the wrong amino acids, and would have the wrong function. In other words, mutation and disaster.
Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
Regulatory proteins in eukaryotes that are involved in controlling the onset of transcription are called?
operators.....
Two processes involved in using DNA to make proteins?
Transcription and translation
What is the primary function of a transcription factor?
To ensure that a gene is used at the right time and that proteins are made in the right amounts.
Purpose of transcription?
The purpose of transcription is to produce a protein with a specific function. DNA is copied into a strand of mRNA and mRNA is read and copied into a protein to carry out some function for the cell. It is the first step in protein synthesis.
What are the 7 classes of protein based on function?
kinases, enzymes, peptidases, antibodies, ribosomal proteins, transcription factors, ion channels
What is a transcription factor?
regulatory proteins
What is the product of transcription and translation?
proteins
Why is it important that transcription and translation take place exactly every time?
So that the proteins coded for have the correct structure so that they will function properly.
What do translation and transcription work together and make?
Proteins
What is the ultimate product of transcription and translation?
proteins
Regulatory proteins can exert ther effects when before transcription during transcription after transcription during translation or all of these?
during translation
Role of chaperone proteins?
Chaperone proteins function to move molecules (such as mRNA from the nucleus to the cytoplasm). They are also called heat shock proteins because they protect the molecule (mRNA) from heat which would degrade the molecule (mRNA) and ruin the process (such as transcription).
The transcription and translation of genes into proteins is called?
encoding.
How would transcription errors as DNA is copied into RNA affect the proteins that are produced?
The proteins would have the wrong shape, would be made of the wrong amino acids, and would have the wrong function. In other words, mutation and disaster.
