The process by through which the instructions that are present in a DNA is transformed into proteins is called gene expression.
The term is related to to the total number of genes that are inherited from the parents in such a way that a gene contains many information related to the building of proteins and hormones that are necessary for the human growth.
<u>Explanation:</u>
The term Gene expression refers to the transfer of the DNA instructions into proteins. It is the main process that helps a human body responding to the varying environment. It is the main factor that controls and regulates the amount proteins production. The steps transcription and translation is involved in the protein production process
The traits from the parents of an individual like blood group type, color of eye are passed to their children. These are passed through genes. These also passes some diseases also. A gene contains information related to the amount of hormones and proteins to be produced which is done by the gene expression.
Answer:
Following are the methods used by plants to encourage cross-pollination.
1) Wind: Wind is the agent through which pollen grains of the flower flew in the air and falls on the stigma of another flower.
2) Bees: Bees are also called pollinators because they help in the transfer of pollens from one flower to another flower and causes cross pollination.
3) Water: There are some plants in which cross pollination occurs through water. Pollens drop into the water and transported to another flower through water flow.
Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
Answer:
Option A
Explanation:
Given -
Man has X-linked recessive trait . Thus its genotype can be represented as
YX'
Woman has normal vision with homozygous genotype i.e "XX"
A cross is carried out between the above two parents thereby producing following offspring -
Y X’
X XY XX’
X XY XX’
Out of four offspring two are boy "XY" which do not have Red-Green Color blindness
While the two daughters "XX' " have Red-Green Color blindness
Thus, all the daughters produced have Red-Green Color blindness. Thus the chance of having a daughter with color blindness is 100 percent
Option A
