The question is incomplete as it does not have the option which are:

A) There are 20,000 genes.

B) Each gene codes for one protein.

C) Any other regions are "junk" DNA.

D) There are also genes for RNAs other than mRNA.

E) The species is highly evolved.

Answer:

D) There are also genes for RNAs other than mRNA.

Explanation:

The protein-coding sequence refers to the sequence which can code for a protein and is therefore also known as the coding sequence.

The coding sequence codes for the protein by producing a messenger molecule which caries the message or codes for the protein called mRNA.

But the cell also requires other types of RNA like tRNA or rRNA which are sloe encoded on the genetic material.

In the given question, since the genome contains the 20,000 protein-coding region which codes for protein shows that it also contain the coded information not for only proteins but for molecules other than protein like RNAs.

Thus, the selected option is the correct answer.

In mice, Gray color is considered to be dominant over white. Show the parent genotypes, the Punnett squares and give the phenoty

siniylev [52]

Answer:

See the answer below

Explanation:

Let us assume that the gray color in mice is represented by the G allele and the white color is represented by g allele. For a cross between a homzygous gray mouse and a white mouse:

Genotype of the gray mouse - GG

Genotype of the white mouse - gg

Crossing the two parents

GG x gg

F1 Gg Gg Gg Gg

All (100%) the offspring at the F1 would have the genotype Gg and would be gray in color since G is dominant over g. (See the attached image for the Punnet's square).

Parenteral Feeding is high in Dextrose which is a form of sugar. The Carbohydrate breakdown of the feeding is what raises the client's serum glucose. The client is also more than likely to be a Diabetic as the body's natural insulin should have broken down the Carbohydrate after six hours.

Explain why biomes are not tyically classified by temperture

12345 [234]

Answer:

Explanation:

Biomes are typically not classified by temperature, because some biomes can experience extreme temperatures from one season to the next. Other biomes might have a more consistent temperature throughout the year.
