Answer:
The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation.
Explanation:
The molecular clock is also known as the “evolutionary clock” or “gene clock”. These was studied by scientists suchs as Darwin, and it made possible for paleontologists to study humanity evolution. <em>Through this idea we talk about the biological concept of heredity: we inherit information in the form of genetic molecules (usually DNA) from the previous generation</em>. This is possible thanks to Mutation. In mutation, DNA and protein sequences evolve DNA and protein sequences evolve over time and among different organism.
I. Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits.
F. Seeds protect and nourish plant embryos, and fruits protect the seeds.
C. In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators.
B. Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals.
A. Flowers attract animal pollinators carrying pollen from other plants of the same species.
D. Floral parts of the saprophyte protect the reduced female gametophyte from drying out and from UV radiation.
Answer:
The correct answer is - in DNA molecules.
Explanation:
The instructions or the information for the creation of the protein is held in the DNA molecule inside the nucleus in eukaryotic organisms while present in the cytoplasm in prokaryotes.
The DNA molecule has coded all the information for the particular protein by the two processes transcription and translation. Transcription is the first step which makes a copy of the DNA is complementary in the form of mRNA, The second step involves the decoding mRNA into an amino acid chain with the help of ribosomes.
Explanation:
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production.
