A critical portion of the promoter of highly expressed, tissue-specific genes, like the ovalbumin gene, lies between 24 and 32 bases upstream from the site at which transcription is initiated. This region often contains a consensus sequence that is either identical or very similar to the oligonucleotide and is known as the .

This region often contains a consensus sequence that is either identical or very similar to the oligonucleotide 5'-TATAAA-3' and is known as the TATA box.

Explanation:

A critical portion of the promoter of highly expressed, tissue-specific genes, such as the ovalbumin gene, ranges between 24 and 32 bases upstream from the site of initiation of the transcription.

Usually, this region contains a consensus sequence that is either identical or very similar to the oligonucleotide 5'-TATAAA-3' and is known as the TATA box.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
