What is the evolutionary advantage of an rna genome in eukaryotic cell virus?

2 answers:

<span>The evolutionary advantage of an RNA genome in eukaryotic cell virus is the possibilities of new genome compositions. The virus have evolved various genetic strategies to convert the data or information of viral genome into an infectious viral species. The cellular response to virus infection will depend on the gene expression strategies exploited by the different type of viruses and these responses must be control to stop the spread of viral infection.</span>

The evolutionary advantage of an rna genome in eukaryotic cell virus is that it <span>have another mechanism for genetic diversity.
For example, RNA exchange between mammalian and avain flu--> pandemic flu
It also have advantage to get around limitation that Eukaryotic only encode one protein.
Viral genomes can be made out of either RNA or DNA. The genomes of RNA viruses can be either single-stranded or twofold stranded RNA, and may contain at least one separate RNA particles

EastWind [94]

Answer:

Gene is present on the X chromosome.

Explanation:

The two main types of chromosomes are autosomes and sex chromosomes. Autosomes regulates the functioning of the body but do not play role in determining the sex of an individual. The sex chromosomes distinguishes between the male and female.

The linkage of sex chromosomes is present in Drosophila as well. The cross between the F1 generation leads to both the red and white eyed flies because the eye color gene is present on the X chromosome. The males contain only one X chromosome and the presence of recessive gene results in the white color whereas in females both the X chromosomes must contain recessive gene for the white color.

Thus, the answer is gene involved is on the X chromosome.

Fittoniya [83]

Answer:

B. similar to the cells just treated with the dye - 0% dead

Explanation:

According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.

Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.

A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid
