Nine Weeks 2 Review Flashcard

Front

Which enzyme fixes the Okazaki fragments in the lagging strand?

Back

Ligase is the enzyme that connects Okazaki fragments on the lagging strand during DNA replication.

Front

What are the gaps between the newly synthesized DNA on the lagging strand called?

Back

The gaps are called Okazaki fragments, which are short sequences of DNA synthesized on the lagging strand.

Front

What are biofilms?

Back

Biofilms are complex communities of various types of microbes that adhere to surfaces, often forming a protective layer.

Front

What is the role of DNA Helicase in DNA replication?

Back

DNA Helicase unwinds the original DNA strand, separating the two strands to allow replication.

Front

What does RNA Primase do during DNA replication?

Back

RNA Primase lays down an RNA primer for new nucleotide bases to initiate DNA synthesis.

Front

What is the function of DNA Polymerase?

Back

DNA Polymerase builds new strands of DNA by adding new nucleotide bases complementary to the template strand.

Front

What is the significance of mesophiles in human health?

Back

Mesophiles are bacteria that thrive at moderate temperatures, typically around human body temperature, and are commonly found in the human microbiome.

Front

Define Okazaki fragments.

Back

Okazaki fragments are short sequences of DNA nucleotides synthesized on the lagging strand during DNA replication.

Front

What is the fourth step in DNA replication?

Back

The fourth step is when Ligase knits together the fragments on the lagging strand.

Front

What are the main types of microbes found in biofilms?

Back

Biofilms can contain bacteria, fungi, algae, and protozoa, forming a diverse microbial community.
