Answer:
The pepsinogen is a protein. All the proteins in the body are coded by the DNA present in the genome. The DNA's 5' -3' strand or the template strand is transcribed by the process of transcription and result in the formation of the mRNA (messenger RNA). the formation of the mRNA by the help of RNA polymerase.
Then the mRNA undergoes the process of maturation. During maturation, splicing of the introns, capping and tailing takes place. The mRNA undergoes translation and forms the amino acids, with the help of tRNA molecule. The tRNA molecules brings the amino acid according to the codon present and these amino acids form a sequence, which later assemble to form a protein.
Hence, the correct sequence would be:
1. The DNA strands unwind, and RNA polymerase binds to the template strand.
2. The synthesis of mRNA begins.
3. The mRNA undergoes intron splicing and exits the nucleus.
4. The tRNA moves through mRNA with the activated amino acids attached to it.
5. The amino acids assemble to form peptide.
Artifact is a really old object.
Answer:
Co-evolution
best describes the type of relationship shown below
Explanation:
Co evolution can also be termed as the common adaptation of two or more species, their genes, traits and the as a group or pair of organs. Due to the same pressure on both the species it occurs, when they undergo same natural selection. The humming bird is also the same example, which has been adapted to the various shapes of the beaks that are used to extract the nectar and flowers are evolved to generate tasty nectar for these humming bird.
Venules are the compositions, which directly follow each capillary bed. Thus, after gas exchange, the blood travels next in the venules.
The venules refers to a small blood vessel in the microcirculation, which permits deoxygenated blood to return from capillary beds to bigger blood vessels known as veins. The venules varies from 8 to 100 micrometer in diameter and are produced when capilaries gathers together.
