The molar concentration of human DNA in a human diploid cell is as follows:
⇒ Total number of chromosomes × 6.023 × 1023
⇒ 46 × 6.023 × 1023
⇒ 2.77 ×1018 Moles
Hence, the molar concentration of DNA in each diploid cell in humans is 2.77 × 10 23 moles.
Fill in the blanks:
(a) Humans reproduce __________. (asexually/sexually)
(b) Humans are__________. (oviparous/viviparous/ovoviviparous)
(c) Fertilization is __________ in humans. (external/internal)
(d) Male and female gametes are __________. (diploid/haploid)
(e) Zygote is __________. (diploid/haploid)
(f) The process of release of the ovum from a mature follicle is called__________.
(g) Ovulation is induced by a hormone called the __________.
(h) The fusion of male and female gametes is called _____________.
(i) Fertilisation takes place in _____________.
(j) Zygote divides to form _____________which is implanted in uterus.
(k) The structure which provides vascular connection between fetus and uterus is called ____________.
Mention two strategies evolved to prevent self-pollination in flowers.
Calculation mistakes
How can we say every chromosome's weight is same moreover multiplication is not correct
Not understandable
The answer is not explained Molar concentration is molarity how can calculate the molarity without knowing the volume of cell?
How this possible actual ans is that 277.058NA OR 2.77058NA(Avogadro's)
2.77058Ã10^20
6.023 * 10^23 is Avogadro Number
Fair enough But we were supposed to find molar concentration and not no of moles.. we need to divide the number of moles by the volume of a typical cell
Wrong answer/ fake site
From where we took the value 6.023
