Pulses and legumes seeds such as chickpea and mung bean are those seeds which contains starch, fat, protein and leucoplasts. Leucoplasts are present in pulses seeds which is responsible for the storage of starch, lipids, and proteins in the seed.

Bacteria are organisms that reproduce asexually. Asexual reproduction can
madreJ [45]

Answer:

Since all forms of bacteria are prokaryotic and in turn unicellular their offspring don’t have to undergo a long period of gestation and growth prior to relative maturity. Whereas any organism (for the most part) in the animila kingdom do and any animal also require a mate. So one major benefit of bacteria being capable of asexual reproduction is they don’t require a mate to reproduce hence the name ASEXUAL. Also, another benefit I vaguely/briefly mentioned is the ability to reproduce at a faster rate than many if not all eukaryotic organisms. For example E.coli a type of bacteria can reproduce in as little as 20 minutes if I recall correctly.

The PCR primer ‘D7S820’ is used to amplify the D7S820 locus. Using this gel below, determine whether each person (M1, P1, P2, C1
Ahat [919]

Answer:

1) M1 is heterozygous since it contains 2 bands, which means that it contains one recessive and one dominant allele

P1 is homozygous for this locus, since it contains a single band or is known to be homozygous for the locus or gene.

P2 is hetozygous for this locus because two bands appear in which each band represents one allele for the gene.

ChildC contains two gel bands, representing two alleles and is therefore heterozygous

P1 is the father of the child C1, if we look at the gel, each father shows a similar band, one coinciding with the mother and the second with the father p1

As for the paternity study, the PCR test is not useful, since it provides asymmetric results, thus only one strand information will be provided, and because the DNA is double-stranded, a more complete study is required.:
