JY Unit 2 DNA

Front

What is produced by transcription?

Back

mRNA (messenger RNA) is produced by the process of transcription, where a segment of DNA is copied into RNA.

Front

What is produced by translation?

Back

Proteins are produced by the process of translation, where the mRNA sequence is decoded to form a polypeptide chain.

Front

What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA?

Back

The correct amino acid sequence is Met-Pro-Val.

Front

How many nucleotides equal 1 amino acid?

Back

3 nucleotides correspond to 1 amino acid in the genetic code.

Front

What does DNA determine?

Back

DNA determines the traits of living things, including physical characteristics and biological functions.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template that carries genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during protein synthesis, matching them to the mRNA codons.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides, with a sugar-phosphate backbone and nitrogenous bases (A, T, C, G) paired in the center.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA before cell division.
