What is one of the jobs of RNA polymerase?
RNA polymerase (green) synthesizes a strand of RNA that is complementary to the DNA template strand below it. Transcription is the first step in decoding a cell’s genetic information.
Where is RNA polymerase found?
the nucleolus
RNA polymerase I is located in the nucleolus, a specialized nuclear substructure in which ribosomal RNA (rRNA) is transcribed, processed, and assembled into ribosomes (Table 1). The rRNA molecules are considered structural RNAs because they have a cellular role but are not translated into protein.
What is the central dogma of life?
The central dogma states that the pattern of information that occurs most frequently in our cells is: From existing DNA to make new DNA (DNA replication?) From DNA to make new RNA (transcription) From RNA to make new proteins (translation).
Is RNA a life?
The RNA world hypothesis suggests that life on Earth began with a simple RNA molecule that could copy itself. The RNA world hypothesis suggests that life on Earth began with a simple RNA molecule that could copy itself without help from other molecules. DNA, RNA, and proteins are central to life on Earth.
What would happen if RNA polymerase is not working properly?
If RNA polymerase malfunctions, one of the subunits of rRNA will not be transcribed from DNA. amino acids will not be joined to their tRNA. mRNA cannot bind to rRNA.
Do humans have RNA polymerase?
Catalytic RNA (ribozyme) Functions as an enzymatically active RNA molecule. RNA polymerase is essential to life, and is found in all living organisms and many viruses….RNA polymerase.

What is the difference between DNA and RNA polymerase?
The main difference between DNA and RNA polymerase is that DNA polymerase produces a double-stranded DNA molecule during polymerization whereas RNA polymerase produces a single-stranded RNA molecule during transcription.
Why are there 20 types of tRNA?
A tRNA can be classified based on the amino acid it carries, giving rise to 20 different tRNAs. Alternatively, they can also be grouped based on their anticodon. There are 64 possible codons arising from a combination of four nucleotides.
