Answer #1

1. Pribnow box, TATAAT, transcription

Transcription is the process of formation of using DNA as a template and enzyme DNA dependent RNA polymerase. It takes place in the cytoplasm of prokaryotes and the nucleus of eukaryotes. It begins at a specific region on DNA called as promoter where RNA polymerase and transcription factor binds to form transcription initiation complex.

Eukaryotes and archeabacteria have TATA box called as Hogness box. The consensus sequence is TATAAA.

Prokaryotes have TATA box called as Pribnow box. The consensus sequence is TATAAT.

It is present at -10 region.

2. Proteins and rRNA

Ribosomes are membraneless organelles which are common in both prokaryotes and eukaryotes. It is made up of proteins and ribosomal RNA. They are synthesized inside the nucleolus. They participate in the formation of proteins during the process of translation.

According to the guidelines, only first question can be answered. I have answered two for you.

Please rate high.
