FLASHCARD QUESTION

Front

What is the role of DNA polymerase during DNA replication?

Back

DNA polymerase is an enzyme that matches the correct nucleotides to the single strands of DNA, forming new complementary strands.

2.

FLASHCARD QUESTION

Front

What is the significance of the codon UUA in protein synthesis?

Back

The codon UUA codes for the amino acid Leucine.

3.

FLASHCARD QUESTION

Front

How many amino acids are coded for by a sequence of 12 nucleotides in DNA?

Back

A sequence of 12 nucleotides codes for 4 amino acids, as each amino acid is coded by a sequence of 3 nucleotides (codon).

FLASHCARD QUESTION

Front

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

Back

This is an example of a deletion mutation, which causes a frameshift.

5.

FLASHCARD QUESTION

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide in the DNA sequence is replaced by another nucleotide, potentially altering the amino acid sequence.

FLASHCARD QUESTION

Front

What are the main stages of DNA replication?

Back

The main stages of DNA replication include unwinding of the double helix, complementary base pairing, and formation of new DNA strands.

7.

FLASHCARD QUESTION

Front

What is the difference between DNA replication and transcription?

Back

DNA replication copies the entire DNA molecule to produce two identical copies, while transcription synthesizes RNA from a DNA template.
