Ribosomal RNA is produced by nucleolus<span>. Ribosomal RNA associates with a set of proteins to form ribosomes. They physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. Additionally, they bind tRNAs and various accessory molecules necessary for protein synthesis. Nucleolus is the structure within the nucleus that is responsible for the formation of these complex structures. The DNA is transcribed into ribosomal RNA precursor molecule which is later processed into mature rRNA. </span>
Hello!
We all are very well familiar with Mendel's laws of inheritance. Just recalling Mendel's law of independent assortment that states, "alleles of different genes are inherited independently of one another".
Here we have two traits, and we want to know how the alleles of these traits will assort independently during the formation of gametes from two parents.
The two traits are:
- Flower color ( Can be purple or white)
- Seed shape (Can be round or wrinkled)
Here the alleles of the traits are represented by alphabets as:
- purple flowers: P
- white flowers: p
- round seeds: R
- wrinkled seeds: r
We have parent one as PpRr
The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 1.
- Gamete 1: PR
- Gamete 2: Pr
- Gamete 3: pR
- Gamete 4: pr
We have parent two as PpRr :
The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 2 as well.
- Gamete 1: PR
- Gamete 2: Pr
- Gamete 3: pR
- Gamete 4: pr
This shows that there is not restriction that the allele for wrinkled seed r will go with allele of white flower p because its recessive or allele of round seeds R will go with allele of purple flowers P because its dominant. There is no restriction when alleles are assorting into gametes and they can go randomly as per nature's choice with any one.
Hope it helps! :)
Answer:
Soil texture is an important soil characteristic that influences stormwater infiltration rates. The textural class of a soil is determined by the percentage of sand, silt, and clay. Soils can be classified as one of four major textural classes: (1) sands; (2) silts; (3) loams; and (4) clays.
Answer:
Migrate through blood vessels
Explanation:
White blood cells have the ability to perform diapedesis. Diapedesis refers to the emigration of white blood cells through the blood vessels. During the process, white blood cells move along the endothelium of blood vessels and stick to it. The white blood cells squeeze between the endothelial cells to migrate out of the blood vessels.
In this way, white blood cells can reach the site of infection or move from blood to the interstitial fluid to perform immune functions. The ability to migrate in and out of the blood vessels allows the phagocytic neutrophils and macrophages to arrive at the site of pathogen entry, basophils arrive at the site of inflammation to perform their respective functions.
