Most genetic diseases tend to be recessive. why is that?

3 0

If the disease was cause by the dominant allele, every person with said gene would be affected with the disease. if the genetic allele is recessive, both parents can be carriers (hetero) without being affected. that makes it easier for the genes to keep being passed on.

hope this helps!

To investigate the possible presence of introns in three newly discovered genes (X, Y, and Z), you perform an experiment in whic

REY [17]

Answer:

a). At least one intron must be present in gene X.

b). At least two intron must be present in gene Y

c). It is impossible to determine whether there are any introns in gene Z.

Explanation:

Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.

In the context, we get :

a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.

b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.

c). In gene Z, it is not possible to determine the number of introns present in them. In genes X and Y, the Haelll enzyme is present in the intron. Therefore we get less of band after splicing the mRNA to cDNA.

which of the following best describes why invertebrates isn't considered a scientifically valid word when classifying animals

Nutka1998 [239]

Taxonomy used to have two groups of vertebrates and invertebrates. But invertebrates are far more diverse when it comes to the phylogenetic tree. Vertebrates all share same characteristic which is a back bone made of vertebrae, but invertebrates don’t share a common anatomical structure that all have; they are radically different in structure so they can’t be grouped in a single group. You have Arthropoda, which all have jointed limbs and segmented bodies and molt their cuticles. There’s Cnidaria, which most have tentacles and nematocysts and are radially symmetrical. And Mollusca, which have a muscular foot and a part of their body called a mantle. All these groups are invertebrates, but there’s nothing they share in common WITHOUT referring to the fact that they don’t have vertebrae. So basically that’s just an example why they can’t be grouped into one category; they all have different characteristics and are placed in different areas of the animal kingdom’s phylogenetic tree. Hope this helps
