Ans.

Gene are considered as fundamental units of DNA. The similarity in DNA sequences of different organisms reflect a common ancestry, which appears to be shared by all organisms present on earth.

Human DNA shows very less similarity with weeds' (plants) DNA, which is around 18%. Thus, plants show different metabolic functions from humans, such as photosynthesis.

Human DNA shows around 26% similarity with yeast (fungus) DNA, as yeasts have some housekeeping genes, same as genes present in humans. For example, genes to uptake energy from sugar breakdown.

Human DNA shows 44 % similarity with fruit fly (insect) DNA. Mammals, such as humans and insects share genes, which are responsible for their growth and structures.

Human DNA shows 92 % similarity with DNA of mouse as they both are mammals and share many common genes.

Human DNA shows 98 % similarity with DNA of chimpanzee. That is why, chimpanzees are considered as closest relative of humans.

Brainlest to most explained person. What is genetically modified food?

sattari [20]

Genetically modified foods are foods that have been engineered (changed/altered) to produce from the original food to have a change in DNA using genetic engineering. For example cotton candy grapes, there isn’t such thing as a real cotton candy grape, the flavor of the grape been modified to taste like cotton candy.

What type of mutation has occurred in the dna of people with sickle cell anemia? (look back, if you need to, to see what causes

strojnjashka [21]

People with two copies of the sickle cell gene have the disease. People who carry only one copy of the sickle cell gene do not have the disease, but may pass the gene on to their children. Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. This small defect in the beta globin gene causes a problem in the beta globin part of hemoglobin, changing the way that hemoglobin works.
