Front

What is the correct amino acid sequence for the mRNA code AUG GCA AAC CGU?

Back

Met-Ala-Asn-Arg.

Front

DNA is copied during a process called ______________ which results in an identical copy of itself.

Back

Replication.

Front

Which 2 molecules form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

What amino acid is represented by the codon UUA?

Back

Leucine.

Front

What is the function of mRNA in protein synthesis?

Back

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

Front

What is the role of tRNA in protein synthesis?

Back

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

Front

What is the process of transcription?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid.
