he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies

Answers

Answer 1

Answer:

We could feed them with another type of food free of silver salts.

Explanation:

When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.

If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

The option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.

What is RNA polymerase?

RNA polymerase may be defined as a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. This enzyme is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.

RNA polymerase binds to DNA, separates the strands, then uses one of the strands as a template from which to assemble nucleotides into a complementary RNA strand.

It uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.

Therefore, the option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.

Answer:

before the common ancestor of all extant life.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

The current genetic code evolved before the common ancestor of all extant life i.e that are still in existence or alive.
