Brain loses 5 to 10% of its weight between the
ages of 20 and 90. One study found that the volume of the brain was 15% less in
older adults than in younger adults. On average, the brain loses 5% to 10% of
its weight between the ages of 20 and 90 years; brain volume also decreases.
Answer:
a) both parents
Explanation:
autosomal recessive means that both copies of the "no tail" allele must be inherited in order to produce a dog with no tail, therefore the answer is both parents
Answer:
U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
Explanation:
The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).
The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.
Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
