An organism has 28 pairs of chromosomes in its diploid somatic cells. How many chromosomes are in its gametes?
diploid = 2n, haploid = n
2n = 28 pairs = 28×2 = 56, n = 28
gametes are haploid = n = 28 total chromosomes
RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.
Answer: I think it is true! Sorry of it is wrong :)
