In cocker spaniels, solid color (A) is dominant over spotted (a), and black coat color (B) is dominant over red (b). If two soli

d black dogs were crossed several times and their offspring were eighteen solid black and five spotted black puppies, the genotypes of the solid black parents would most likely be:________.A. Аа Bb x AA ВbB. Аа BB х аа Вb C. Aa Bb x Аа Bb D. AABB x Aa Bb E. aa Bb x AA Bb

Answer:

<h2>A</h2>

Explanation:

As given;

Solid color is dominant on  spotted color,  

so A is dominant on a.

black coat color (B) is dominant on red (b) color

so B is dominant over b.

cross between two solid black dogs several times and their offspring were 18 solid black and 5 spotted black puppies. so the parents will be Аа Bb x AA Вb, due to the effect of dominant.

50 points!!! please define the philogenetic species concept and please explain it with an example, it's realy urgent

Phylogenetic species concept (PSC) The concept of a species as an irreducible group whose members are descended from a common ancestor and who all possess a combination of certain defining, or derived, traits (see apomorphy). ... "phylogenetic species concept." A Dictionary of Biology. .

Or

The biological species concept has its limitations (although it works well for many organisms and has been very influential in the growth ofevolutionary theory). ... In thisexample, Ensatina salamander lineages A and B are separate species.Each has a common ancestor that individuals of other species do not.

Which of the following is NOT an accurate description of protein synthesis and folding?
julia-pushkina [17]

Answer:

OPTION b. "<em>The 3D shape of a protein is determined largely by the ribosome forming the protein" </em> is NOT an accurate description of protein synthesis and folding.

Explanation:

<em>a. Many copies of a protein can be synthesized simultaneously from the same mRNA</em>.  TRUE. As a ribosome moves along the mRNA chain synthesizing a new protein, another ribosome might follow it, synthesizing another protein from the same mRNA chain. And so on. So, at the same time, many ribosomes might be attached to the mRNA, synthesizing many copies of the protein, but at different development levels. The mRNA chain together with many ribosomes is called a <em>polyribosome</em>.

b. <em>The 3D shape of a protein is determined largely by the ribosome forming the protein</em>.  FALSE. What determined the 3D structure of the protein is the amino acid sequence of that particular polypeptide. Each amino-acid has different properties (hydrophobic, hydrophilic, positively charged, negatively charged) and they interact with each other by different bonds that depend on those poperties. So the amino acids composing the proteins and their interaction, is what models the structure of the protein.

c. <em>The entire chain of amino acid exits the ribosome before it begins folding into its 3D shape</em>.  TRUE. When the ribosome reaches the end codon, the elongation process has finished, and the new protein leaves the ribosome and is translocated to the RER lumen where it is going to get folded.

d. <em>The first encoded amino acid in every protein is methionine. </em>TRUE. Almost always, the first amino acid located by the tRNA is the methionine, codified by the initiation codon AUG. This amino acid is frequently eliminated at the end of the process.

Only the proteins that the bacteria Escherichia coli (E. coli) needs are synthesized at any given time. For example, when lactos
nataly862011 [7]

The correct answer is A. Lac repressor.

Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.

Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.

When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.
