Living Systems: Unit 3 LC1 Review

Front

How is mRNA made?

Back

mRNA is made when it 'reads' the code (base sequences) in the DNA and forms a molecule of complementary bases.

Front

What bases are contained in DNA?

Back

DNA contains the bases adenine, thymine, guanine, and cytosine.

Front

Which molecule is made during transcription?

Back

mRNA is made during transcription.

Front

What forms the sides (backbone) of the DNA ladder?

Back

The sides of the DNA ladder are formed by deoxyribose (sugar) and phosphate.

Front

What is Thymine replaced with in RNA?

Back

Thymine is replaced with Uracil in RNA.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is transcription?

Back

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

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.
