Answer:

B. It was passed to the individual by a gamete from the father.

Explanation:

<u>DNA is transferred</u> to the next generation <u>via gametes</u>, which are produced during <u>meiosis</u>. During meiosis, <u>half of the genetic material</u> is <u>transferred</u> from parent cell to their gametes. Therefore, among the given options, only <u>B is correct</u>.

Option A is not correct because it talks about <u>somatic cells;</u> whereas, in somatic cells, <u>genetic material is not transferred half</u> rather duplicate first and then a complete duplicated set of genetic material is transferred.

Option C is also not correct because only <u>one gamete (sperm)</u> fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.

The central dogma of molecular biology is that biological information flows from?
Sergio039 [100]

Answer:

DNA to messenger RNA (mRNA) to protein.

Explanation:

Central Dogma is a term that refers to the two step process through which information flows from the sequence of DNA into a sequence of RNA (the process of transcription) and finally takes the form of proteins (the process of translation)

Francis Crick was the first scientist who proposed the term of "Central Dogma".

Significance of Central Dogma:

  • This is the process that ensures that genetic information of all living organisms is preserved and transmitted without any alteration or changes into their offspring.
  • It is a process that intricately explains the logical mechanism through which DNA stored in our chromosomes express themselves into functional forms called proteins.
  • This was the process which let us know the important roles of molecules like ribosomal RNA, transfer RNA and messenger RNA in the process of protein formation.
  • The process has immense importance in understanding the latest advances in RNA technology that can further help in investigation and diagnosis as well as treatment of many critical diseases.

Hope it helps!

How does climate affect the rate of weathering
slava [35]
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
