Front

What is the structure that carries genetic information in cells?

Back

DNA

Front

Which form of RNA carries amino acids from the cytoplasm to the ribosome?

Back

Transfer RNA (tRNA)

Front

What type of sugar does RNA contain?

Back

Ribose

Front

Which type of genetic mutation is considered the most damaging?

Back

Insertion mutation

Front

What is the primary function of ribosomes in cells?

Back

To synthesize proteins by translating mRNA.

Front

What is the role of messenger RNA (mRNA) in gene expression?

Back

To carry the genetic code from DNA to the ribosome for protein synthesis.

Front

What are the building blocks of proteins?

Back

Amino acids.

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 is a silent mutation?

Back

A genetic mutation that does not change the amino acid sequence of a protein.
