uysha [10]3 years ago
7 0

Answer:

numbers

Explanation:

If you were to gain Quantitative data that would mean that the data includes numbers such as there were five students with a syndrome. on the other hand, there is qualitative data. Qualitative data is a description of something, like the dots on a small object.

Stem cells begin to transfor into different types of cells in the human body in a process known as cell differentiation.
Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types. 
Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.

allochka39001 [22]

Answer:

The correct answer is - c) Pathology.

Explanation:

Mycology is the branch of biology in which students study fungi and their characteristics including their biochemistry, taxonomy, and genetics.

Agronomy is the other branch of biology that deals with agriculture and its practices and work to improve the crops.

Phycology is the study of algae and their characteristics including their biochemistry, taxonomy, and genetics.

The disease and its causes are studied under the pathology branch o  biology therefore, red rust would be studying in this discipline.

E. coli DNA polymerase III is both highly accurate and highly processive. a) Describe how Pol III avoids the incorporation of im
kogti [31]

Answer/Explanation:

DNA polymerase is the enzyme responsible for replicating DNA. It is hugely important that is performs its functions accurately, as if incorrect bases are incorporated this can lead to mutations that disrupt the structure and function of genes. It adds nucleotides in a 5' - 3' direction only.

DNA polymerase III also has high processivity, which means that for every time it binds DNA, it is able to add many bases before it becomes dissociated.

A. DNA polymerase avoids the incorporation of improperly paired nucleotides in two ways:

  • The first way depends on the structure of the enzyme. If the nucleotide that the enzyme is in the process of adding is not complementary to the template, then the nucleotide will not align with the template, and thus it is more inefficient to add. This inefficiency means the nucleotide is more likely to leave the active site before it is added, and DNA polymerase can replace it with the correct nucleotide.
  • It also has proofreading capabilities. This means, when an incorrect base is added, it recognises the error and can fix this. It can do this because it possesses 3'-5' exonuclease activity. That means, it can chop out incorrectly added bases.

B. Ribonucleotides are the nucleotides that are incorporated into a growing RNA molecule. They are different from deoxyribonucleotides because of the differences in the sugar backbone (ribose vs deoxyribose). Their incorporation would disrupt the structure and function of the DNA, leading to problems with transcription and replication.

DNA polymerase avoids incorporating these nucleotides primarily because of the structure of the enzyme. Ribonucleotides cannot fit into the active site of DNA polymerase due to what is called a "steric filter" or "steric gate". This gate/filter function is performed by specific amino acid residues which usually have a bulky side chain and thus block the incorporation of the 2'OH of the ribose sugar (which is lacking in the deoxyribose sugar)
