Answer: b) organelles must interact with each other to synthesize and transport proteins.
Explanation:
The DNA is a genetic material which is converted into mRNA by the process of transcription in the nucleus. The protein synthesis takes place in ribosomes where the translation of mRNA to protein takes place. The proteins are transferred to rough endoplasmic reticulum for the packaging into membrane structures called as cisternae. The proteins are transferred to the golgi apparatus where they are modified, sorted and packed in vesicles. The vesicles take away proteins outside the cell. In golgi apparatus the proteins are tagged with the aminoacids so that they can be targeted to the particular cell.
Answer:
DNA
Explanation:
DNA is a nucleic acid. It is a polymer of deoxyribonucleotides that are bonded together by phosphodiester bond to make long DNA strands. DNA is the most stable biomolecule in the history of life on earth and continues to serve to store the genetic information of living beings. Several species-specific sequences are DNA are conserved during evolution. This makes the DNA the best molecule to store any valuable information.
RNA is comparatively more reactive and prone to mutations due to the presence of ribose sugar and uracil base in it. The structure of a protein is determined by DNA nucleotide sequences. Any change in DNA would also change the structure of a protein.
Answer:
f a flower contains all four main parts ( sepals , petals, stamens, and carpels), it is called a complete flower. Sepal: This typically green, leaf-like structure protects the budding flower. Collectively, sepals are known as the calyx. Petal: This plant structure is a modified leaf that surrounds the reproductive parts of a flower.
Explanation:
Help this help you to choice...
2 + 9x = 20
2 - 2 + 9x = 20 - 2
9x = 18
9x/9 = 18/9
x = 2
