The correct answer is that "<span>RNA polymerase binds to the promoter, which precedes the gene only on the template strand of DNA."

A gene is best described as </span>a chain<span> of DNA or RNA which codes for a molecule that has a </span>characteristic<span>. </span>for the duration of<span> gene expression, the DNA is first duplicated into RNA. The RNA </span>can be immediately practical<span> or be the intermediate template for a protein that </span>plays<span> a </span>characteristic<span>. The transmission of genes to an organism's offspring is </span>the idea<span> of the inheritance of phenotypic </span>traits<span>.</span>

What would be of most importance to goblet cells and other glandular epithelia?
konstantin123 [22]

The given question is incomplete as options are not provided, however the options  are as follows :

- Golgi bodies

-lysosomes

-microvilli

-multiple nuclei

Answer:

The correct answer is - golgi bodies.

Explanation:

Goblet cells and glandular epithelial cells are cells that produce and secretes a specific type of products that are termed as the mucin to protect the skin and layer mucous membrane they place.

These cells are characterized by a large amount of Golgi body and endoplasmic reticulum as they are involved in the exocytic pathway which means they secrete, glycoproteins, mucin, and other substances. Golgi bodies needed to modify, synthesis, and secretion.

Thus, the correct answer is - golgi bodies.

How does nature “select” phenotypes, such as bird beaks? Check all correct explanations. 1. Organisms can choose the genes that
finlep [7]

Answer:

The correct answers would be options 3 and 4.

Natural selection refers to a natural phenomenon by which organisms with survival traits tend to survive and reproduce more as compared to the organisms which lack such traits.

Due to this differential reproduction, survival traits tend to pass on to the offsprings and over several generations the phenotypic frequency of the population changes.

n Drosophila melanogaster, forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal b
makkiz [27]

Answer:

Proportion of the F2 male with red eyes and forked bristle will be 1/4

Explanation:

forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).

Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)

A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes

    X+X+b+b+  x    Xfbb

the F1 gives   1/2X+Xf 1/2b+b

                      1/2X+Y  1/2b+b

intercross of F1

      Proportion of the F2 male with red eyes and forked bristle will be

      forked bristle= Xfy = 1/2 and for red eyes  2/4= 1/2  = 1/2x1/2 =1/4
