some bacteria called nitrogen fixers convert atmospheric nitrogen to ammonia
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.:
All species in the same area
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.
Answer:
The correct answer will be option-Telomerase is an enzyme that increases the length of linear chromosome ends
Explanation:
Telomerase is a reverse transcriptase enzyme which adds the length of DNA by adding the guanine-rich repetitive sequences called telomeres at 3' end of the DNA.
The enzyme not only adds the telomere but also maintain its length in the organism. The telomerase activity possesses several roles one of which is that it protects the end of the DNA from DNA damage and neighbouring chromosomes.
Since telomerase adds the repetitive sequences at the end and thus increases the length of the DNA thus is the correct answer.
