How is dna the basic of life?

Biology
1 answer:
Allushta [10]3 years ago
6 0


DNA is considered the molecule of life because it contains the instructions that ensure the continuity of life. Employment of DNA to code for protein is the basis of all life on earth. 

In all living things, inherited DNA  is used to code for amino acids  which when joined or linked together in a deliberate specific  manner form polypeptides which make up proteins. These proteins are responsible for  structure and function of cells. 

For example DNA provides information to make  four polypeptide (two beta and two alpha ) chains  which make up hemoglobin, the protein that functions as the oxygen carrier in red blood cells. In summary,

DNA → protein →  trait, and that relationship is the physical basis of life.

Since each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber
zmey [24]

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

What two conclusions makeup Mendel's law of segregation
sashaice [31]
1st conclusion: Organisms inherit two copies of each gene, one from each parent.

2nd conclusion: Organisms donate only one copy of each gene in their gametes.
Thus the two copies of each gene segregate or separate during gamete.

What density-dependent growth limiting factors kept the human population relatively low prior to the advent of agriculture?
4vir4ik [10]

Answer:

Limited food supply and competition

Explanation:

Density dependent factors are those which in general lead to reduction of growth rate of population when the population density increases. One of such factor is availability of food and competition.

Whenever the density increased to an extent where the resources or available food becomes scarce or limited,then the growth rate of population decrease.  These factors generally lead to logistic growth pattern of population.
