LS1.1-LS1.4 Biology Review

Front

What is the role of DNA in protein synthesis?

Back

DNA provides the information needed to correctly sequence the amino acids during protein synthesis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is the expected mRNA sequence transcribed from the DNA segment GCTGTGTGAGGCAGA?

Back

CGACACACUCCGUCU.

Front

What amino acids are coded by the RNA sequence UUUCCUCAA?

Back

Phenylalanine-Proline-Glutamine.

Front

What structure is found in both viruses and cells?

Back

Nucleic acid.

Front

Define protein synthesis.

Back

The process by which cells build proteins based on the information encoded in DNA.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

What is transcription in biology?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs.
