RNA test prep

In mRNA, each codon is specific for coding one

amino acid

Where in the cell does the process of copying the DNA message into mRNA occur?

the nucleus

Ribosomes need mRNA and tRNA to help build proteins. Which statement correctly describes their roles in the process?

mRNA carries the genetic instructions for building proteins to the ribosome, while tRNA brings the corresponding amino acids to the ribosome based on the instructions in the mRNA

Through meiosis & fertilization, each parent contributes one of two genes for a particular trait. Different forms of a gene are called

alleles

What happens during Step 1 of protein synthesis (aka transcription)?

DNA -> RNA

What happens during Step 2 of protein synthesis (aka translation)?

RNA-> Protein

Transcription

the biological process where a cell creates a single-stranded RNA molecule by copying the genetic information from a DNA sequence

Translation

Takes the information passed from DNA as messenger RNA and turns it into a series of amino acids bound together with peptide bonds

DNA->

RNA

RNA->

Protein

Mutations

a random error in gene replication that leads to a change, A change in the DNA causes a change in the protein.

RNA phosphate backbone is made from

sugar ribose

Ribosome is the

place where proteins are made

Anticondon

Transferring the amino acids

RNA has the nitrogen base

Uracil

What are proteins made up of

amino acids

AUG is the

starting codon
