Answer:

polygenic inheritance

Explanation:

Hair color is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. ... If the receptor is not activated or is blocked, melanocytes make pheomelanin instead of eumelanin. Many other genes also help to regulate this process.

The cytoplasm divides during this segment of mitosis _____.

-BARSIC- [3]

Answer:

<em>The correct option is D) cytokinesis</em>

Explanation:

Mitosis can be described as a process in a cell replicates to form two identical copies of itself.

Cytokinesis can be described as the last stage of cell division for both prokaryotes and eukaryotes. During this stage, the cytoplasm eventually divides and the cell splits into two with equal portions of cytoplasm in each side. Although the mechanism of cytokinesis is different for both plants and animals yet it is the final stage for both the cell type in which the cytoplasm splits.

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.
