Which of the following is NOT a product of transcription? O None of these O tRNA O A new strand of DNA O mRNA O rRNA

Answers

Answer 1

Transcription does not produce a new strand of DNA. Here option C is the correct answer.

Transcription is the process by which genetic information in DNA is used to synthesize a complementary RNA molecule. The products of transcription are mRNA (messenger RNA): This is the type of RNA that carries the genetic code from the DNA to the ribosomes, where it is translated into a protein.

rRNA (ribosomal RNA): This is the component of ribosomes, the organelles where protein synthesis occurs.

tRNA (transfer RNA): This is a small RNA molecule that carries amino acids to the ribosomes during protein synthesis. During transcription, a new strand of RNA is synthesized but not a new strand of DNA.

What enzyme makes vitamin K active?

Vitamin K is found in nature in the quinone oxidized state and is converted by that of the enzyme vitamin K epoxide reductase towards the hydroquinone form (vitamin KH2) (VKOR). This same vitamin K-dependent enzyme -glutamylcarboxylase then uses vitamin KH2 as an active cofactor.

How does vitamin K function as a cofactor for which enzyme?

Blood coagulation factors II, VII, IX, and X, as well as inhibitors such Protein C and S and bone matrix protein, are all synthesized with the help of vitamin K.

Which numerical setup can be used to determine the atomic mass of the element boron?.

Answers

According to calculations, boron has an atomic mass of 79.9062 amu.

The mass of each isotope in relation to its abundance has been reported as the element's relative atomic mass. The atomic mass is stated as follows:

AMU = mass x abundance

The bromine isotopes that are currently accessible are:

0.5069% abundance and 78.92 amu for isotope 1

Isotope 2 has an abundance of 0.4931% and 80.92 amu.

Submitting the data for the boron atomic mass unit:

amu = 78.92 x 0.5069 + 80.92 x 0.4931

The  statement that  best describes what would happen if the trees in this area of first were removed and the area were converted to farmland is   only a small number of the original species would survive in the  changed environment. Option D.

What happens when an  habitat undergoes  changes?

When a habitat undergoes significant changes, such as the conversion of a hardwood forest to farmland, many of the species that were present in the original ecosystem may not be able to adapt to the new conditions and may be unable to survive.

On the other hand, some new species may be able to thrive in the modified habitat and may move in to fill the niches left vacant by the departing species.

Hence, it is unlikely that an equally large number of new species would be able to move in to replace the original species, as the new habitat may not provide the same resources and conditions that the original habitat did.

Evolutionary taxonomists classify or reclassify animals on what basis?

Answers

Evolutionary taxonomy, evolutionary phylogeny, or Darwinian taxonomy attempts to classify organisms based on a combination of phylogenetic relatedness (common ancestry), ancestor-descendant relationships (serial ancestry), and degree of evolutionary change. It is a branch of biological classification.

Groups of species can be expected to give rise to new groups because this type of taxonomy allows consideration of entire taxa rather than individual species.

This concept found its best-known form in modern evolutionary synthesis in the early 1940s.

The evolutionary taxonomy differs from the pre-Darwinian strict Linnaean taxonomy (which only produces an ordered list) in that it produces an evolutionary tree.

Phylogenetic nomenclature requires each taxon to consist of a single ancestor node and all its descendants, whereas evolutionary taxonomy allows groups to be excluded from the parent taxon. (For example, allow paraphyletic taxa.

What joints are condyloid joints?

Answers

A condyloid joint is a type of synovial joint within an ellipsoidal cavity of the other bone.

An ovoid convexity on one articular surface of the bone articulates with another bone with an ellipsoidal hollow. This joint can rotate but not move. Jaw and finger joints, for example, are condyloid joints. Condyloid joints are also known as condylar joints, bicondylar joints, or ellipsoid joints.

The articular capsule is found between the two linked bones in condyloid joints. The synovial joint is protected by articular cartilage. Certain ligaments around the joint give support. They also aid in injury prevention by restricting mobility.

Condyloid joints, like saddle joints, provide for two degrees of freedom of movement. Such joints permit movement such as abduction/adduction and flexion/extension (circumduction).

The ball and socket joint allows axial rotation but not the condyloid joint. Condyloid joints, in other words, have non-axial motions. Due to the oval form of the joints, however, minimal circumduction may be achieved at such joints.
