T<span>chromatins make up </span>chromosomes<span>. Chromatins are just a combination of DNA, histones(a type of proteins) and RNA. Strands of DNA are considered as chromatins and when these strands combine, this forms the </span>chromosome<span>. </span>Chromatin<span> is untangled and unfolded DNA, while </span>chromosome<span> is condensed DNA. T</span>he chromatin, dispersed in the nucleus, is a set of filamentous DNA molecules associated to nuclear proteins called histones. Each DNA filament is a double helix of DNA and thus a chromosome.

A standard PCR cycle includes three steps: denaturation (95°C), annealing (55°C), and elongation (65°C).
xz_007 [3.2K]

Answer:

Denaturation process: The DNA template  

Annealing process: Primers  

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.

Question 7 in the attachment, please help thank you so much!
sertanlavr [38]

Answer:

Here are the answers:

a. 4  Cell determination as an issue in the *rest is missing*

b. 4  They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.

c. 4  I and III only

Explanation:

The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.

Cleavage Planes:

Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.

Cell Differentiation:

Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
