Draw a picture of DNA replication. Label the direction each strand is going, the enzymes involved with each step, the leading an
Step2247 [10]

Answer:

The fork is drawn to emphasize its similarity to the bacterial replication fork depicted in Figure. Although both forks use the same basic components, the mammalian fork differs in at least two important respects.

First, it uses two different DNA polymerases on the lagging strand.

Second, the mammalian DNA primase is a subunit of one of the lagging-strand DNA polymerases, DNA polymerase α, while that of bacteria is associated with a DNA helicase in the primosome. The polymerase α (with its associated primase) begins chains with RNA, extends them with DNA, and then hands the chains over to the second polymerase (δ), which elongates them. It is not known why eucaryotic DNA replication requires two different polymerases on the lagging strand. The major mammalian DNA helicase seems to be based on a ring formed from six different Mcm proteins; this ring may move along the leading strand, rather than along the lagging-strand template shown here.

The illustration shows biotic and abiotic factors in a pond ecosystem. Which are biotic factors of the pond ecosystem?
Hatshy [7]

Answer:

All organisms that have life, both plants and animals.

Explanation:

You didn't provide an illustration, but I guess I can still help. Biotic factor means that it has life, abiotic means it's not alive (hence the a- at the beginning.) Some biotic factors of a pond ecosystem include: earthworms, fishes, frogs, plants and insects.

Elanso [62]

Answer:

The genotypes of the original parents are

  • Male: X⁺Y  
  • Female: X⁻X⁻

The Chi-square analysis leads us to accept the prediction of the parental genotypes.

How do stabilizing and disruptive selection differ? how do stabilizing and disruptive selection differ?
skelet666 [1.2K]

Disruptive selection is made of natural selection which favor both extreme phenotype and both  from one extreme in directional selection. Stabilizing selection is favors the middle phenotype, average trait value over two extreme trait values.

Both the selection are disruptive selection favors phenotype while stabilizing selection favors average phenotype in population , eliminating both extreme.Disruptive selection also known as diversifying selection.

Stabilizing selection is natural selection pursue population towards the average or median . Normally environment favors average phenotype within a population.Both are two natural selection , affect the distribution of phenotype within a population,Applies to  a phenotype trait.
