Answer:

Please find the explanation to how protein is former from the listed components below.

Explanation:

The process by which protein is synthesized in an organism is called GENE EXPRESSION. The DNA is the genetic material that holds/stores information necessary for the building of a protein molecule, which is responsible for the traits possessed by organisms.

The process of gene expression occurs in two stages namely: transcription and translation.

- TRANSCRIPTION is the process by which DNA is used to synthesize a mRNA molecule. The mRNA is an information conveyer that transports the encoded information out of the nucleus into the RIBOSOMES, where translation occurs.

- TRANSLATION is the process by which mRNA is used to synthesize amino acids in a sequence that encodes proteins. The sequence of mRNA is read in a group of three nucleotides called CODONS. This is done in the ribosome by another type of RNA called transfer RNA (tRNA) using its anticodons. The tRNA then carries the corresponding amino acid to the growing peptide chain (amino acid sequence).

- The sequence of amino acids eventually code for a particular protein molecule.

A hybrid tall and hybrid plant is crossed with a short pea plant
Phoenix [80]

Answer: 25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.

Explanation:

In this explanation, I'm assuming that the allele "T" for tall plants is dominant to the allele "t" for short plants, like in Gregor Mendel's pea plant experiment.

A homozygous tall pea plant will have the genotype "TT" and a homozygous short plant will have the genotype "tt" because homozygous means that both alleles are identical. Since "T" is dominant over "t", any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is. Let's look at a Punnett square for this cross:

Each of the offspring has one "T" allele, so they are all tall plants. This is because the "T" allele is dominant over the "t" allele, so a plant with one "t" allele and one "T" allele will only display the traits of the "T" allele, which in this case is a tall pea plant.

If we cross the offspring, we get a Punnett square that looks like this:

The "TT" and "Tt" crosses both have at least one "T" allele, so they are tall plants. However, the last cross "tt" doesn't have any "T" alleles and is short, because it is homozygous recessive . Since 1 out of 4 pea plants are short, or 1/4, the probability of a short pea plant from a heterozygous cross is 25%.

Osteoarthritis is a disease that results in a thinned or absent layer of cartilage surrounding bones, causing bones to rub again
Diano4ka-milaya [45]

The correct answer is connective tissue.

Osteoarthritis refers to the most general kind of arthritis, influencing various individuals all over the globe. It takes place when the protective cartilage on the terminals of the bones wears down with time.

However, osteoarthritis can destruct any joint in the body; the ailment most usually influences the joints in the knees, hands, spine, and hips. Cartilage is a flexible connective tissue, found in the articulating surfaces of the joints. Thus, the condition osteoarthritis affects the connective tissue.
