Answer:sorry if this doesn’t help but The everyday activities of human are constantly degrading the quality of the environment which ultimately results in the loss of survival condition from the earth. Solve Questions. Write a general essay in about 200 words on
Explanation:ya
Allopatric Speciation
describes why similar organisms do not interbreed because of a physical barrier.
Explanation:
The specific situation in which the population of identical species doesn’t interbreed or leaves in isolation with each other is referred as ‘allopatric speciation’. It is also considered a specification of geographical factors.
The factors that work as a barrier to the process of breeding between same groups of organisms are- mountain formation, formation of water bodies, agriculture etc. These natural and human occurrences affect the geography of a place that influences the separation in species.
The most important factor is B.Latitude
Ans.1. False.
RNA or ribonucleic molecules are polymer of nucleotide molecules that perform various functions in a cell. rRNA is referred as ribosomal RNA and are involved in synthesis of ribosomes along with proteins. Ribosomes are described as molecular factory for protein synthesis, hence, rRNA plays an important role in protein synthesis.
Thus, given statement is false.
Ans.2.
Transcription is defined as a process, by which a parental DNA molecule gets transcribed into a RNA molecule with the help of RNA polymerase enzyme. The RNA molecule is then, translated into a specific polypeptide chain or protein.
According to central dogma of molecular biology, genetic information flows from a DNA molecule to a protein. During this, first step includes transcription (formation of RNA from DNA) and second step includes translation (formation of protein form RNA).
Thus, transcription plays an important role in the central dogma of molecular biology.
