A proteinâs function is determined by the properties of its amino acids. Which replacement of one amino acid with another is least likely to affect the proteinâs function?

a. A hydrophilic amino acid is replaced by a hydrophobic amino acid. an amino acid with a C=O group is replaced by an amino acid with an O-H group.
b. A charged amino acid is replaced by an amino acid with a side chain consisting of a group with three C-H bonds.
c. A hydrophobic amino acid is replaced by a charged amino acid.
b. A negatively charged amino acid is replaced by a positively charged amino acid.

Answers

Answer 1

Answer:

an amino acid with a C=O group is replaced by an amino acid with an O-H group

Explanation:

When an amino acid is substituted by another with opposite properties the replacement will modify the structure (and consequently also the function) of the resulting protein. For example, it is expected that the replacement of amino-acid residues with different solubility will alter the protein’s structure and this protein will establish different interactions with water, cell structures, or further segments of the protein. Therefore, in the cases above enumerated, only C-O and O-H groups have similar properties (i.e. they are hydrophilic and have polar bonds), and thereby it is expected that this replacement has no significant incidence on the protein’s structure and function.

Answer:

Atoms themselves are composed of three different types of particles—protons, neutrons, and electrons. A proton carries one unit of positive† charge (Dufay's vitreous electricity) and an electron carries one unit of negative charge (Dufay's resinous electricity). A neutron carries no charge; it is neutral.

why is it beneficial for DNA to transition from free floating DNA to a chromosome form during the cell cycle?

Answers

Answer:

During the cell cycle, the transition of DNA from its free form to chromosome is beneficial because it allows the equitable division and transmission of genetic information to the daughter cells.

Explanation:

In eukaryotic cells, DNA contains all the genetic information of an individual and is found in the cell nucleus. The way the DNA is found while the cell is in interphase —period without division— is free form, associated with histone proteins, called chromatin.

When cell division occurs, the DNA must replicate and right at the beginning of the division process the chromatin condenses, forming chromosomes. These chromosomes contain the genetic information compartmentalized into genes, making it easier to distribute it equally to each daughter cell.

The main benefit of the condensation of chromatin - nuclear DNA - into chromosomes is to achieve the equitable distribution of genetic information and its transmission to each daughter cell.

Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).

1. Many species of field mice can reproduce several times a year and produce
litters with multiple offspring. However, an ecologist noted that the population size
of mice in a California grassland remains stable from year to year. The factors that
keep natural populations from increasing are collectively called
A. X-factor.
O B. limiting factors.
O C. carrying capacity.
O D. birth, death, immigration, and emigration.

Answers

Answer:

Limiting Factors

Explanation:

limiting factors determine a habitat's carrying capacity. hence the factor that keep natural population from increasing are collectively called limiting factors. Thus option B is correct.

What do you mean by carrying capacity of a species ?

In an ecosystem the number of organism can survive successfully under certain resources referred as carrying capacity.

If a species population exceeds the environment's carrying capacity, the population depletes due to less availability of resources.

Several factors influence an environment include availability of food which is paramount  for the survival of a species.

Water is the another essential factor which help animal in food digestion, regulate body temperature and elimination of waste products.

Ecological Conditions of an environment  have an effect on carrying capacity of environment.

Space is another factor that provide a shelter to animals for survival and reproduction.

Thus option B is correct.
