Transcription is the correct answer
Answer:
Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.
Explanation:
DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.
Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.
Thus, the correct answer is option (b).
Answer:
The growth factor receptors have a kinase domain while the Cytokines receptors do not contain a kinase domain as part of their structure.
Explanation:
The two are signaling molecules that control cell activities in some manners, such paracrine, endocrine and autocrine manners.
The receptor kinase domain can be specific for substrate sites in which phosphorylation occurs.
