Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino acids.

a. True
b. False

Answers

Answer:

a. True

Explanation:

Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).

Explanation:

Chemostat culture with protozoa Tetrahymena thermophila protozoa have a minimum doubling time of 6.5 hours when grown using bacteria as the limiting substrate. The yield of protozoal biomass is 0.33 g per g of bacteria and the substrate constant is 12 mg l1 . The protozoa are cultured at steady state in a chemostat using a feed stream containing 10 g l1 of nonviable bacteria. (a) What is the maximum dilution rate for operation of the chemostat

Answers

Answer:

The correct answer is - 3.3 g/L.

Explanation:

It is known that if endogenous metabolism is not important then,

µnet = µmax = 0.693/doubling time.

Given:

doubling time = 6.5 hr, therefore,

µmax = 0.693/6.5 = 0.1/h

Formula:

First, maximum dilution rate Dmax,

Dmax = µmax*[S0]/{Ks + [S0]}.........(1)

Steady-state cell concentration, X

X = Yx/s{[S0] - KsD/(meumax - D)..........(2)

Solution:

Yx/s = 0.33 g/g-substrate;

Ks = 12 x 10-3 g/L; [S0] = 10g/L,

puting value in (1)

Dmax = 0.1 * 10 / (12 x 10-3 + 10)

= 0.1/h.

Now it is given that operating D is 1/2 of Dmax, therefore,

D in our case will be = 0.05/h

concentration of protozoa cells from equation (2).

Therefore, X = 0.33*{10 - 12 x 10-3 * 0.05/(0.1 - 0.05)} = 3.3 g/L.

will All mutations become more common in a population.

Answers

Answer:

False

Explanation:

Mutations are changes in the genetic (nucleotide) sequence of the genome of an organism. According to their effects, mutations can be divided into beneficial, neutral and detrimental for the fitness of the organism, i.e., its ability to survive and reproduce in a given environment. Moreover, mutations can also be classified according to the type of cell that suffers the mutation into 1-somatic mutations that occur in somatic cells and are not inherited, and 2-germinal mutations that occur in germinal cells (i.e., gametes) which can pass to the next generation. In regard to the question above, only those mutations that occur in the germline and are beneficial for the organism (in the environment in which it lives) are expected to become more common in a population.

Answers

Answer:

bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.

Answer:

Choice D

Explanation:

When you translate the RNA, you replace C’s with G’s (and vice versa) and A’s with U’s (also vice versa). So, you get GUU UUA CGC UAG. Then you read the codon chart to get your answer. Hope it helps :)

The sequence of the amino acids which is being produced when this RNA is translated is Val - Leu - Arg - Stop. Thus, the correct option is D.

What is a Codon?

Codon can be defined as the sequence of three consecutive nucleotides in the nucleic acids such as a DNA or RNA molecule which codes for a specific amino acid. Certain codons are responsible for the signal of the start or end of the translation process.

Codons are universal in nature throughout the different living organisms. There are about 64 different codons which codes for 20 standard amino acids in the cell. There are three stop codons in the genetic code which stop the process of translation of protein molecules including UAG, UAA, and UGA.

The sequence of the amino acids which can be produced when this RNA is translated 5'-CAA AAU GCG AUC-3' will be Val - Leu - Arg - Stop.

Therefore, the correct option is D.

What is the function of histones- proteins that aide in dna replication

Answers

Answer:

Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.

Have energy to dissolve metals and other subtances?​

Answers

Explanation:

Dissolving metals is a chemical property that takes place when water or strong acids react with metallic objects. Chemical forces pull metal atoms from the object, causing it to break apart and leave the atoms floating freely in solution. Solubility depends on the acids and metals involved. Lead and iron react easily, while platinum and gold are much harder to dissolve.

Which type of selection occurs when a population experiences a shift in diversity toward the larger organisms? o stabilizing selection directional selection disruptive selection adaptive selection​

Answers

Answer:

Directional selection

Explanation:

This because directional selection is type selection in which a particular phenotype is choosen and favored among several other phenotypes which cause a shift in diversity of larger population of organisms causing the population to shift in over time in a direction towards the choosen phenotype.

Directional selection

The distribution of population elements along a continuum of homogeneity to heterogeneity with respect to one or more variables is characterized as population diversity. Measures are specified using variance-based interpretations that can be applied to qualitative data.When individuals with qualities on one side of the population's mean survive or reproduce more than those on the other, this is known as directional selection.Directional selection occurs when a population experiences a shift in diversity toward the larger organisms
