Unit 5 DNA and Protein Synthesis

Front

What is DNA replication?

Back

The process by which a cell makes an identical copy of its DNA.

Front

Why is DNA replication considered to be semi-conservative?

Back

Each new strand contains a parental strand and a new daughter strand.

Front

What is the function of transfer RNA (tRNA)?

Back

It delivers the correct amino acid to the ribosome during protein synthesis.

Front

What are the three types of RNA?

Back

mRNA - messenger, tRNA - transfer, rRNA - ribosomal.

Front

What type of mutation causes sickle cell anemia?

Back

Point Mutation.

Front

What type of bonds hold the nitrogen bases in the DNA rungs together?

Back

Hydrogen bonds.

Front

What is the role of messenger RNA (mRNA)?

Back

It carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is a frameshift mutation?

Back

A mutation that results from the insertion or deletion of nucleotides, altering the reading frame of the genetic code.

Front

What is the structure of DNA?

Back

A double helix formed by two strands of nucleotides, with complementary base pairing.

Front

What are nucleotides?

Back

The building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
