The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.

In which layer of the ocean are you likely to find microscopic plants called phytoplankton?
Answer:
The Epipelagic Zone (sunlight zone)
Explanation:
The depth of this zone is about 200 meters (656 meters) below the ocean's surface. Phytoplanktons dwell there because sunlight penetrates this zone which facilitates the process of photosynthesis.

What was known before Franklin and Wilkins conducted their studies of DNA? Select three options.
DNA is found in the nucleus of a cell.
The human genetic code is made of 50,000 genes.
Organisms store and transmit genetic information.
DNA has a double-helix structure.
Cells contain protein molecules.
The correct answer will be-
1. DNA is found in the nucleus of a cell
2. Organisms store and transmit genetic information
3. Cells contain protein molecules.
Explanation:
The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.
Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.
Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.
DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.
Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.
Thus, 1. DNA is found in the nucleus of a cell
2. Organisms store and transmit genetic information
3. Cells contain protein molecules.
are the correct options.

The primary function of DNA is to?
Answer:
The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Explanation:
A in Biology class last year.
DNA is the genetic material of many organisms. The primary function of DNA is to store the genetic information that results in protein synthesis.
What is DNA?DNA or deoxyribonucleic acid is the nucleic acid that includes the instruction and the information that codes for protein synthesis. It is a crucial part of hereditary that passes the genetic traits from one generation to another.
The major role that it plays in an organism is to store the genetic code and information so that it can be used to synthesize proteins through the process of transcription and translation.
Therefore, DNA stores genetic information.

a bird has a short sturdy beak that allows it to crush hard tough grains what does the beak's form to a specific type of food describe about the species of bird
Answer:
Niche
Explanation:
The siboglinid tube worm, found at deep-sea hydrothermal vents and cold seeps, has no digestive tract. It relies on symbiotic bacteria that live in the tube worm’s tissues. The bacteria oxidize hydrogen sulfide or methane for the worm.
What type of relationship is this?
Answer:
mutualism
Explanation:
There is a mutual benefit in both parties.
The relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism, a type of symbiotic relationship in which both organisms benefit from the interaction.
What is a mutualistic relationship?In a mutualistic relationship, both organisms benefit from their interaction with each other. This is different from parasitic or commensal relationships, where one organism benefits at the expense of the other, or where one organism benefits while the other is neither helped nor harmed. In the case of the siboglinid tube worm and the symbiotic bacteria that live in its tissues, the tube worm benefits from the bacteria's ability to oxidize hydrogen sulfide or methane, which provides the worm with a source of energy and nutrients. This is important because the tube worm has no digestive tract of its own and cannot obtain food directly from the environment.
Hence, the relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism.
