Both dolphins and whales still have their hip (pelvic) bones present. These bones connect and transfer the weight of the trunk to the lower limbs.
Thus, <em>the presence of the pelvic bone may indicate that whales had ancestors that walked on land</em>.
The answer is T-G-C-A-A-T-G-C-T
Answer: <em>D. Causes an accumulation of lipids in brain cells</em>
Explanation:
Tay-Sachs disease is caused by a genetic mutation in the <em>HEXA</em> gene. It is an autosomal recessive disease that causes the mutation on an enzyme, which metabolizes <em>GM2 Ganglioside</em> in nerve cells, this leads to a build-up of the molecule in brain cells. At the moment there is no cure for the disease, only support treatment is available.
<span>The mRNA is made by using the gene AAACAGGTCCCA as a template for complementary base-pairing. The pairings are: G (Guanine) to C (Cytosine), C to G, T (Thymine) to A (Adenine), and A to U (Uracil, as Tyhmine doesn't occur in the RNA). The resulting mRNA is UUUGUCCAGGGU.</span>
Answer:
The conservation of “junk DNA” sequences in diverse genomes suggests that they have important functions.
Explanation:
Transposons move by means of a DNA intermediate, whereas retrotransposons move by means of an RNA intermediate.
