How does a bacterial chromosome differ from a eukaryotic chromosome? A bacterial chromosome is a circular, double-stranded DNA molecule with associated proteins. A eukaryotic chromosome is a linear, double-stranded DNA molecule with many associated proteins, including histones.

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I
Westkost [7]

Answer:

C(t) = C_oe^{-kt}

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

\dfrac{dC}{dt} decrease proportionally to Concentration C

i.e

\dfrac{dc}{dt} \alpha - C

\dfrac{dc}{dt} = -k C

\dfrac{dc}{c} = -k dt

\int \dfrac{dc}{c} = -k \int dt

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C)  - ㏑C₀ =  -kt

\dfrac{C}{C_o} = e^{-kt}

C(t) = C_oe^{-kt}

∴

The concentration of drug in blood at any time t is:

C(t) = C_oe^{-kt}

Two butterflies mate and a genetic mutation causes the offspring to be a different color. Is this an example of biological evolu
brilliants [131]

A genetic mutation results in the offspring of two butterflies being a different color. There is no evidence of biological evolution in this.

In populations of organisms, biological evolution is the change in hereditary features through successive generations. When diversity is added to a population through gene mutation or genetic recombination or removed by natural selection or genetic drift, features undergo evolutionary alteration. the gradual genetic change within a population. What is the most likely outcome if two species rejoin after many generations if allopatric speciation has place after a population split into two different populations?

Crick et al found that not all combinations of (+) and (-) frameshift mutations results in suppression and an rII+ phenotype. Wh
GenaCL600 [577]

Answer:

d. Two of the above explanations are correct.

Explanation:

A frameshift mutation is commonly known as a genetic mutation that occurs as a result of the indels such as the addition or removal of certain nucleotides in the sequence of a DNA that is indivisible by three. In the presence of addition or removal, the reading frame from the initial translation to a different one. Thus, the correct option is option d.

In E. coli, there is a mutation in a gene called dnaB that alters the helicase that normally acts at the origin of replication.
kvasek [131]

Answer:

When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.

When plants make flowers, gene A is expressedin whorls 1 and 2, gene B is expressed in whorls 2 and 3 and gene C in whorls 3 and
Sati [7]

Answer:

The correct answer would be option D) no gametes.

Explanation:

The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.

Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.

The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.

Thus, the correct answer would be option D) no gametes.
