Types of RNA
Transcription
100

Which one is double stranded (double helix)

RNA or DNA

DNA

100

How many stop codons are there and why does the body have so many?

there are a total of three stop codons and The body always has backups just in case if something goes wrong

100

How many different types of RNA are there and what are their names 

There are three different types of RNA and their names are messenger RNA, Ribosomal RNA and Transfer RNA

100

Where does transcription take place 

in the nucleus 

200

Which one is smaller DNA or RNA

RNA

200

How many possible codons are there 

there are 64 possible codons 

200

What is the purpose of messenger RNA (mRNA)

Copies genetic instructions from DNA in the nucleus. Then it carries the instructions to a ribosome in the cytoplasm  

200

What is the first step of transcription

An enzyme bonds to the DNA and signals it to unwind 

300

Which one is made up of nucleotides 

RNA or DNA

Both

300

What are the three letter codes of the start and stop signals

UAA, UGA, UAG and AUG

300

What is the purpose of Ribosomal RNA 

Helps form a ribosome. This is where the proteins are made 

300

What is the second step of transcription

After the DNA unwinds the enzyme reads the bases in one of the DNA strands 

400

Which ones are in the nucleus RNA or DNA

Both

400

How many amino acids make up a protein

20 amino acids

400

What is the purpose of Transfer RNA (tRNA)

Bring amino acids to the ribosome. The amino acids are then joined together to make a protein 

400

What is the last step of transcription

Nucleotides are joined together to make a complementary strand of mRNA

500

Which one helps build proteins DNA or RNA

RNA

500

What is a codon 

A codon is a group of 3 bases, each codon stands for one amino acid or else for a start or stop signal

500

What happens during transcription

A strand of DNA is copied to make a strand of mRNA
