Ribosomes cell and protien
Answer: Deoxyribonucleic acid (DNA)
Ribonucleic acid (RNA
Explanation:
Nucleic acids are simply referred to as the macromolecules which aids in the storage of genetic information. It should also be noted that nucleic acids enable the production of protein.
Nucleic acids include the Deoxyribonucleic acid (DNA) and also the Ribonucleic acid (RNA).
Answer:
C) Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.
Explanation:
Apoptosis is a natural process taking in the cell which causes the physiological and biochemical changes in the cell which could cause the death of the cell.
The apoptosis is controlled at the genetic level therefore apoptosis is also known as the programmed cell death.
The studies have shown that the process is involved in the development of the finger and the toes in humans and the sequences controlling the process has been conserved during the evolution in a different organism.
This shows that humans and nematode have the same conserved sequence of apoptosis but the natural selection does not control the apoptosis.
Thus, the selected option is the correct answer.
Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.
percentage of chloroplast gene inherited from R plant is a)0%
Answer:
A, pleiotropy.
Explanation:
Pleiotropy - genes that have multiple phenotypic effects. Remember that phenotype means a physical characteristic caused by a gene, such as eye color or fur patterns.
Incomplete dominance - when neither allele is dominant and they mix together in the phenotype. A popular example is a red flower crossing with a white flower and resulting in a pink flower.
Epistasis - when two genes contribute to the phenotype, but one gene completely masks another gene. An example would be labrador fur colors.
Multiple alleles - 3 or more alternative forms of a gene, but only 2 alleles can occupy an organism. An example is blood type.
Hope this helps!
