A chromosome is a double-stranded helix during... Gap-1 Mitosis Gap-2 Meiosis

Biology
1 answer:
Effectus [21]3 years ago
6 0

Explanation:

During mitosis, the two chromatids of each pair separate to opposite ends of the cell so that at the end of mitosis each chromosome is a single unit. Evidence suggests that such a single (unreplicated) chromosome contains one continuous DNA double-stranded molecule running along its length

Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?
daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

                monomer/glucose     glycosidic bond    branching

1.starch              α glucose          1-4 and 1-6               branch and unbranced

  amylose                                       1-4                          unbranched

  amylopectin                               1-4 and 1-6              branched

2. dextran          α glucose          1-6                           branched

3. cellulose        β glucose           1-4                          unbranched, linear        

4. glycogen       α glucose           1-4 and 1-6              branched (shorter

                                                                                     branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.

Suppose a woman with haplotype L1 and a man with haplotype L2 have a son. The son then marries a woman with haplotype L3. If thi
-Dominant- [34]

Answer:

AA AT TT

GG AG AG AG TG TG TG

GC AG AC AG TC

ó

AC TG TG TC

CC AC AC AC TC TC TC

Explanation:

Haplotype research served to discover the origin of genetic mutations that today manifest as pathologies.

It is very important to know that there are no equal haplotypes in two or more different humans.

They are the allelic constitution of multiple loci for the same chromosome.

Furthermore, haplotypes are very good for studying population genetics.

I leave you a table that will help you for this exercise or many more, where the haplotype system is outlined.
