Answer:
everyone has dna becasue our dna tells us to do things
Explanation:
Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Based on the genotype of AB blood, the a and b genes are codominant.
Since both A and B antigens are equally prevalent on red blood cells, the A and B genes are related in a codominant manner.
<h3>What is gene?</h3>
- A gene is a fundamental building block of heredity and a DNA sequence of nucleotides that codes for the production of a gene product, either RNA or protein.
- DNA is initially transcribed into RNA during gene expression.
- The RNA may execute a specific function directly or may serve as an intermediary template for a protein.
<h3>What is codominance?</h3>
- In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
- Animals that exhibit codominance include roan cattle and speckled chickens, which have alleles that express both red and white hair as well as both black and white feathers.
- Plants also exhibit codominance.

Phytoplankton
Phytoplankton are the main organisms responsible for oceanic photosynthesis. These one-celled plants obtain most of their carbon dioxide not from the air but from the depths of the ocean. Much of the oxygen they produce eventually makes its way into the atmosphere, however.
