Write a note on RNA polymerase

Answers

Answer 1
Answer:

Answer:

Ther RNA polymerases (abbreviated as RNAPs or RNA pols), represent a group of conserved enzymes that synthesize RNA from DNA templates

Explanation:

These enzymes are used to synthesize different RNA species such as, amon others, messenger RNA (mRNA), transference RNA (tRNA), noncoding RNAs (ncRNAs), etc. During the gene transcription, the RNA pol is used to produce a mRNA molecule that subsequently is translated into protein
Answer 2
Answer:

Answer: By definition, RNA polymerase or ribonucleic acid polymerase is a multi-subnunit enzyme that catalyze the process of transcription where an RNA polymer is synthesized from a DNA template.

Explanation:

RNA polymerase are highly conserved in evolution among eukaryotes, bacteria, archea and some viruses. Bacreria and archea has a single RNA. RNA polymerase are considered as molecular motors because of their stepwise movement on DNA. They are also central to biology information flow since they catalyzed templated polymerization reaction.

A pine tree is a _____.
-bryophyte
-angiosperm
-gymnosperm
-fern

Answers

A pine tree is a gymnosperm. Gymnosperms are taxonomic class that will include plants whose seeds are not enclosed in an ovule (like a pine cone). These are often referred to as softwoods. Gymnosperms are seed-bearing vascular plants, such as ginkgo, yews, cycads, and conifers. (Conifers are the higher classification of a pine tree)

The U.S. Fish and Wildlife service is responsible for protecting _______.a. migratory birds
b. endangered species
c. aquatic species
d. all of the above

Answers

The answer is D. Not only is the Fish and Wildlife service responsible for protecting endangered species. their mission is also includes conservation and making sure wildlife has a safe place to exist. This includes birds that fly, live underwater, and roam on the ground.

Answer:

The correct answer would be d. all of the above.

There are three basic functions of the U.S. Fish and Wildlife Service:

  • It assists the application and development of the organization which supervise or take care of environmental ethic for the society. It is based on the scientific knowledge (about wildlife and fish), ecological principles, and moral responsibility.
  • It guides the development, management, and conservation of resources of fish and wildlife of the nation.
  • It administers the national program to provide opportunities to people to understand, appreciate, and use wisely the fish and wildlife resources.

Thus, they not only protects fish but also other wildlife species and their natural habitats.

Explain the role of lactate dehydrogenase in enabling C. parvum to continue producing ATP by glycolysis

Answers

The lactate dehydrogenase enzyme carries the lactic acid fermentation.

What is Lactic acid fermentation?

Lactic acid fermentation may be defined as a process through which muscle cells and bacterial species like Lactobacillus oxidize NADH by transforming pyruvate into lactate.

The enzyme lactate dehydrogenase carries the conversion of pyruvate into lactate. It involves the oxidation of NADH.

During this anaerobic process, ATP is produced in an average amount which provides the energy to muscle cells in oxygen-deficient conditions.

Therefore, it is well described above.

To learn more about Lactic acid fermentation, refer to the link:

#SPJ2

Answer:

Lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells. LDH catalyzes the conversion of lactate to pyruvate and back, as it converts NAD+ to NADH and back. This is how it allows glycolysis to continue.

. Limb bones within unrelated animals that have the same basic structures are considereda. vestigial structures.
b. homologous structures.
c. embryological.
d. analogous structures.

Answers

When you have unrelated animals in biology which have limbs that have the same basic structure we consider these things to be homologus. As the first poster noted, an example is a wing of a bird or a hand of a human. When we're talking about analogous structures, we're talking about things which perform the same function yet don't have the same structure.
