Answer:

a. There are different possible ways that homologous pairs might line up

c. Different alignments of homologous pairs will cause different combinations of alleles in gametes.

Explanation:

The law of independent assortment, proposed by Mendel, states that the alleles of one gene segregate into gametes independently of the alleles of another gene. This means that the segregation of one gene does not affect another. This law of independent assortment is evident during gamete formation in sexually-reproducing organisms know as meiosis. Specifically, in the Metaphase 1 stage of meiosis 1, homologous chromosomes (similar but non-identical chromosomes received from each parent) lines up at the metaphase plate (cell equator).

The lining up of chromosomes in this stage occurs randomly making it possible for chromosomes to align in different possible ways. The way/manner the chromosomes align at the equator determines which chromosome combination gets separated into which gamete. The homologous chromosomes are randomly distributed at the cell's equator before segregates into gametes. This random orientation enables the alleles of each gene on a chromosome to combine in different random ways, hence, allowing genetic diversity in the resulting gametes (sperm and egg) they get segregated into.

How many amino acids would be encoded in the sequence 5′ AUGUUACGGAAU 3′ by a non-overlapping and maximally overlapping code?

Reil [10]

<span>In non-overlapping code there would be four amino acids, because there are just four triplets in the code, of which none is the stop codone. For maximally overlapping code there would be ten amino acids encoded, the four starting from the first letter: AUG, UUA, CGG, AAU, then three starting from the second letter: UGU, UAC, GGA, and the three starting from the third letter: GUU, ACG, GAA.</span>
