Biology EOC Review: DNA, DNA Replication and Protein Synthesis

Front

What type of macromolecule is responsible for storing and transmitting genetic information?

Back

Nucleic acid

Front

When does translation end?

Back

When a stop codon comes up on the mRNA

Front

True or false: The process of translation requires all three types of RNA: mRNA, tRNA and rRNA.

Back

True

Front

According to Chargaff's rule, what is true about the amount of adenine and thymine in a DNA sample?

Back

The amount of adenine will equal the amount of thymine.

Front

Which strand must be made in Okazaki fragments during DNA replication?

Back

Lagging strand

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic code from DNA to the ribosome for translation.

Front

What is the function of tRNA in translation?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is the role of rRNA in the ribosome?

Back

rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

What is DNA replication?

Back

The process of making a copy of DNA before cell division.

Front

What is a codon?

Back

A sequence of three nucleotides on mRNA that codes for a specific amino acid.
