2024 DNA/RNA Protein Synthesis

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine (A-T) and Guanine pairs with Cytosine (G-C).

Front

If a DNA molecule has 15% adenine, what percentage of thymine would it have?

Back

15% thymine, because adenine pairs with thymine.

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a template for protein synthesis, carrying the genetic information from DNA to the ribosome.

Front

What are the three types of RNA and their functions?

Back

1. mRNA (messenger RNA) - carries genetic information from DNA to ribosomes. 2. tRNA (transfer RNA) - brings amino acids to the ribosome during protein synthesis. 3. rRNA (ribosomal RNA) - makes up the ribosome and helps in protein synthesis.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is the enzyme responsible for adding nucleotides to a growing DNA strand during DNA replication.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded, contains deoxyribose sugar, and has thymine; RNA is single-stranded, contains ribose sugar, and has uracil instead of thymine.

Front

What are amino acids and their role in protein synthesis?

Back

Amino acids are the building blocks of proteins; they link together in a specific sequence to form proteins.

Front

What is transcription in the context of protein synthesis?

Back

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

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA or RNA is translated into the amino acid sequence of proteins.
