What is the enzyme that synthesizes mRNA from DNA?

Back

RNA Polymerase

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that have the potential to develop into different cell types.

Front

What type of mutation is represented by the change from ATTTGAGCC to ATTGAGCC?

Back

What is the complementary mRNA sequence to the DNA strand AACTGAA?

Back

UUGACUU

Front

What are the base pairs in DNA?

Back

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

Front

What is the function of DNA Polymerase?

Back

DNA Polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a pre-existing chain.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.

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 transcription in biology?

Back

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