Biology Unit 5 review DNA RNA

Front

How many strands does RNA have?

Back

RNA has one strand.

Front

Where does RNA polymerase know where to start copying down instructions in the DNA molecule?

Back

RNA polymerase starts copying by looking for Promotors in the code.

Front

How many nucleotides make up a codon?

Back

A codon is made up of 3 nucleotides.

Front

What is the correct sequence for protein synthesis?

Back

The correct sequence is DNA → mRNA → tRNA → Protein.

Front

What is the significance of the sequence of Nitrogen Bases in DNA?

Back

The sequence determines the traits that an organism will possess.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome.

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What is transcription in the context of DNA and RNA?

Back

Transcription is the process of copying a segment of DNA into RNA.
