What is the process of transcribing DNA into RNA?

Back

Transcription is the process where the DNA sequence is copied into messenger RNA (mRNA) by the enzyme RNA polymerase.

What is the complementary RNA sequence for the DNA sequence TAC-TTA-CGA?

Back

AUG-AAU-GCU

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are eukaryotes?

Back

Eukaryotes are organisms whose cells contain a true nucleus and membrane-bound organelles.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

What is the role of RNA polymerase in transcription?

Back

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

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder with sugar-phosphate backbones and nitrogenous base pairs.

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 difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is the function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.
