Answer:
A) The middle-of-the-road style
Explanation:
The middle-of-the-road leadership style is plotted in the center of the grid and shows balanced concern for production and people. Employees are neither satisfied nor dissatisfied with their jobs, and their performance is average.
It should be adequate in all four management areas :
1) Interpersonal skills.
2) Intrapersonal skills.
3) Executive abilities.
4) Leadership potential.
hence option A) The middle-of-the-road style is the right choice.
<u>Answer</u>: The correct statements are-
1. At any stage of mitosis a cell has twice as much as DNA in G1.
2. Metabolically active cells can exit, and sometimes re-enter, the cell cycle.
<u>Explanation</u> :
1.. The cell cycle consists of <em>4</em> distinct phases - M phase which is the mitotic phase and the G1, S and G2 phase which together form the interphase. The interphase is preparatory phase wherein the cell grows in size, replicates the DNA etc. whereas the M phase is the one where events related to cell division takes place.
2. The cell has <em>2C</em> amount of DNA during G1 but since the DNA replication takes place during S phase, the amount of DNA <em>doubles up to 4 C</em> and remains so in G2 and M phase until cytokinesis results in the formation of 2 daughter cells.
3. Sometimes, the metabolically active cells can exit the cell cycle and become <em>quiescent</em> until the conditions are favourable. When these quiescent cells recieve the right stimulus they can re enter the cell cycle.
4. Extracellular conditions such as nutrient availability, presence of certain mitogens, growth factors etc. do regulate the cell cycle progression. <em>If any of these extracellular facotrs are limiting the cell cycle is arrested.</em>
5. Once the cell cycle starts, it can be stopped without leading to cell death. When this happens it is known as <em>cell cycle arrest. </em>During this arrest several factors are assessed and if theire is need for repair of DNA then that also takes place. Once, the limitations are overcome or the repair is done, the cell cycle can then continue.
Answer:
The production of peptides linking aminoacids through peptidic bonds
Explanation:
Chemically, peptides are synthesized by condensation where the carboxyl group of one amino acid is linked to the amino group of the other amino acid. The most common way to make a chemical peptide synthesis is linking first the carboxyl end of one amino acid to the amino group, not in the other direction. The opposite reaction, starting from the amino end and linking to the carboxyl end, is made in biosynthesis made by living organisms.
Answer:
By preventing bases from being damaged present in phosphate sugar backbone.
Explanation:
The sugar phosphate backbone is a significant structural component of DNA. It comprises of 5-carbon deoxyribose sugars and phosphate gatherings. DNA is twisted into a right-gave twofold helix. The strands are anti parallel for example one runs 3' to 5', the other run 5' to 3'.
This is finished by the sugar phosphate backbone contorting around itself in a curl or coil. The motivation behind this twisting or coiling is to ensure safety of the nitrogenous bases inside backbone, and keep them from being damaged. DNA is entirely stable because of rungs of hydrophobic "ladder" and adversely charged phosphate sugar backbone of DNA. These highlights cause DNA to can repulse water and would not hydrolyzed.
Answer:
3 types are recombination,mutation and immigration
