The correct answer is The shape of a PROTEIN molecule resembles a messy group of coat hangers.
To function, proteins must have the necessary amino acids in a specific sequence and be folded into a specific shape. A sequence is a continuous series. Proteins loop, coil, and crinkle into complicated shapes. The shapes appear more like messy groups of wire coat hangers than stacks of neatly folded dish towels.
Scientists were able to observe the molten magma erupting (Volcanoes) from Earth's crust and the Kola Superdeep Borehole.
The process of DNA duplication is called DNA replication. Replication follows several steps that involve multiple proteins called replication enzymes and RNA. In eukaryotic cells, such as animal cells and plant cells, DNA replication occurs in the S phase of interphase during the cell cycle.
The most important factor that limits the size of a cell is the ability of the cell to transport materials efficiently into and out of the cell. In this case the size of a cell should have a particular form in order to export and import material.
Answer:
Option B, Dd and Dd
Explanation:
It is given that deafness is a recessive trait.
Let the recessive trait be represented by "d"
Normal hearing is a dominant trait and let it be represented by "D"
It is given that Dr. Smith's parents have normal hearing , hence they can have genotype -
either Dd X DD
Or Dd X Dd
but Dr. Smith has an inherited form of deafness , thus his genotype would be "dd". Considering the genotype of Dr. Smith , his parents would be having genotype Dd and Dd.
Thus option B is correct.
