Raise your 10 paddles high for Dancing With the Stars judge Len Goodman. The stern British reality TV star, 68, who also hosts BBC1's Strictly Come Dancing, married his long-term girlfriend, dance teacher Sue Barrett, 47, Sunday in a surprise ceremony, reports the Daily Mail.
The total length of the human genome is over 3 billion base pairs. The genome is organized into 22 paired chromosomes, plus the X chromosome (one in males, two in females) and, in males only, one Y chromosome. These are all large linear DNA molecules contained within the cell nucleus.
The protein-coding region of the human genome has been shrinking since its discovery. The first sequences published in 2001 predicted 26,000â30,000 genes; a recent evolutionary comparison suggested the number was closer to 20,500. Now, that number might be reduced to approximately 19,000.
