WHEN TRANSPORTING THE MICROSCOPE, HOLD IT IN AN UPRIGHT POSITION WITH ONE HAND ON ITS ARM AND THE OTHER SUPPORTING ITS BASE. AVOID SWINGING THE INSTRUMENT DURING ITS TRANSPORT AND JARRING THE INSTRUMENT WHEN SETTING IT DOWN.
Answer:
It is due to the proofreading activity of RNA polymerase.
Explanation:
RNA polymerase is the most significant enzyme of transcription process which deals with the synthesis of RNA from DNA.
RNA polymerase reads the template DNA or antisense strand of DNA and helps in the addition of correct nitrogen bases to the growing RNA strand that is complementary with respect to the nucleotides present within the template DNA strand.
After the addition of bases to the growing RNA strand the proofreading process take place in to verify that all the incorporated bases within the growing RNA chain is correct or not.If any incorrect base is incorporated in the growing RNA strand then the proofreading process replace that incorrect base with the correct one.
All this processes occur in very quick succession that"s why RNA polymerase can locate a promoter sequence faster than two molecules can collide.
Answer:
the rabbit population grew
Explanation:
Answer: The genotype ratio is 2Ff : 2ff
The phenotype ratio is two normal feathered birds to two silky feathered birds.
Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.
A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.
