A flower is ready to become a fruit where would the instruction be found? A. Nucleus B. Plant ovum C. Mitochondria D. Ribosomes

I am pretty sure it is Nucleus because the definition of nucleus is "the central and most important part of an object, movement, or group, forming the basis for its activity and growth." I hope this helps! Sorry if I am wrong. but a tip is look up what the definitions are and compare to see which fits best:)

Answer:

The correct answer is option A. Nucleus.

Explanation:

Fruits arise from the fertilization of the male gamete and female gamers in the flower.

The flower is the reproductive organ of the plant that carries female reproductive organ carpet and male reproductive organ stamen.

After fertilization zygote formation takes place. A zygote is a single cell that has a nucleus in which chromosomes are present, where all the genetic code about the development of seed and fruit is stored.

Thus, the correct answer is option - A. Nucleus.

scZoUnD [109]

Question is incomplete. Complete question has been attached.

Answer:

A) DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication.

Explanation:

DNA polymerase synthesizes the new DNA strand from the template strands. Both the strands in a DNA molecule act as templates, however both of them have different orientation. It was observed that 3'-5' template DNA produced a new DNA strand continuously in one step. However, 5'-3' template produced new DNA strand in fragments which were joined together later. This observation gave the idea that DNA polymerase is a directional enzyme. It synthesizes DNA in 5'-3' direction so 3'-5' template gave rise to a continuous DNA segment. However, for 5'-3' template, DNA polymerase had to synthesize in opposite direction i.e. 3'-5' which was not possible directly. So the enzyme replicates it in short separate fragments which are later joined by DNA ligase.

Pop quiz: alpha helices are stabilized by hydrogen bonds between the carbonyl group of residues i and the amide group of residue

aalyn [17]

Answer:

Explanation:

Alpha helix is a secondary structure of proteins, it is made of 3.6 aminoacids residues per turn, this structure is possible thanks to local hydrogen bonding between C=O and N-h groups. The result is a cylindrical structure with a hydrogen-bonded backbone and the outside studded with side chains.

Glycin has an -H in its side chain, this makes it a too flexible molecule, therefore it's unusual to find them in alpha-helical structures because their presence could cause the helix to deform. Large R-groups can also affect this stability, phenylalanine has a bulky aromatic side group, this discards it as a stabilizer. Serine has a hydrogen bond donor or acceptor as a side chain, due to the proximity to the main chain it competes with the main chain to form NH and CO bonds. Alanine is the most common amino acid in alpha-helix structures because it has a short and no charged R group (unlike arginine that even when it's short it has a charged R-group), this makes it flexible enough to keep the structure stabilized.

Hope you find this information useful! good luck!
