DNA. RNA, and Protein Synthesis

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It is composed of two strands that coil around each other to form a double helix.

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a single-stranded molecule that plays a crucial role in the synthesis of proteins. It is involved in translating the genetic information from DNA into proteins.

Front

What is the function of Helicase?

Back

Helicase is an enzyme that unwinds and separates the two strands of DNA during replication, allowing each strand to be copied.

Front

What is the role of RNA polymerase?

Back

RNA polymerase is an enzyme that synthesizes RNA from a DNA template during the process of transcription.

Front

What are the three types of RNA?

Back

The three types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). Each type has a specific function in protein synthesis.

Front

What is mRNA and its function?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is tRNA and its function?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis, matching them to the codons on the mRNA.

Front

What is rRNA and its function?

Back

rRNA (ribosomal RNA) is a component of ribosomes, which are the sites of protein synthesis. It helps to catalyze the formation of peptide bonds between amino acids.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids (DNA and RNA). Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the nitrogenous bases in DNA?

Back

The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). A pairs with T, and C pairs with G.
