How many chromosomes are found in a gamete compared to the parental cell?
White raven [17]

Answer:

<em>In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.</em>

What is a tRNA isoacceptor?
Alla [95]


A tRNA isoacceptor is a member of a group of tRNAs with different anticodons but which accept the same amino acid.

An anticodon is a small region on transfer RNA (tRNA) that comprises of three bases which are complementary to a codon in messenger RNA (mRNA).  A codon is simply a set of three nucleotide bases.

If a codon in mRNA is GGG, the anticodon on tRNA for this will be CCC. The codon GGG is the code that calls for the amino acid called glycine.

Why are both biotic and abiotic features important in ecosystems and biomes?
Sati [7]

Answer:

Hope this is helpful! Sorry if my answer is choppy.

Explanation:

Biotic and abiotic features are both important in ecosystems because for example, a biotic factor like a plant, relies on an abiotic factors like the rain and the sun. If the rain were non existent, then the plants would no longer be alive causing a chain reaction in the food system. Biotic factors like plants and animals that are non existent can also cause negative effects in biomes and ecosystems.

Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ________ ends of glucose polymers.
Alex787 [66]

Sequential cleavage from the non-reducing terminals of glucose molecules is required for both glycogen degradation and polysaccharides hydrolysis.

Why non-reducing end is selected for digestion?

A polysaccharide's non-reducing end is the one where an anomeric carbon participates in the glycosidic connection. The elimination of carbohydrate remnants one at a time out from the non-reducing terminal occurs during glycogenolysis and polysaccharides hydrolysis.

  • For example, several enzymes are involved in glycogenolysis in the liver and muscle.
  • An example of such an enzyme is glycogen phosphorylase, which catalyzes the successive dissociation of the alpha 1->4 glycosidic bond that connects two glucose molecules at a non-reducing terminal of glycogen. The last glucose residue is eliminated as alpha-D-glucose 1-phosphate.

That is why non-reducing end of glucose is chosen for digestion or breakdown of the carbohydrate polymer.
