<h2>Sequence code </h2>
Explanation:
DNA template (non coding strand) is always synthesized from 3'-5' direction and the complementary strand (coding strand) will be synthesized from 5'-3' direction; mRNA synthesized will be from 5'-3' direction and will have the same sequence as coding strand(only in place of T, U will be present)
Sequence 1: 3' TACGCTACGATCGTA 5'
Coding strand 1 : 5' ATGCGATGCTAGCAT 3'
mRNA 1: 5' AUGCGAUGCUAGCAU 3'
AUG codes for methionine(Met); CGA codes for alanine(Ala); UGC codes for threonine(Thr); UAG codes for isoleucine(Iso); CAU codes for valine(Val)
so protein 1 will be:
Met-Ala-Thr-Iso-Val
Sequence 2: 3' TACGCTACTATCGTA 5'
Coding strand 2: 5' ATGCGATGATAGCAT 3'
mRNA 2; 5' AUGCGAUGAUAGCAU 3'
AUG codes for methionine(Met); CGA codes for alanine(Ala); UGA codes for threonine(Thr); UAG codes for isoleucine(Iso); CAU codes for valine(Val)
so protein 2 will be:
Met-Ala-Thr-Iso-Val
Both the protein sequence comes out to be same hence function of protein 2 will be same as that of protein 1
Answer:
D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
Explanation:
Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.
The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.
Answer:
46
Explanation:
in mitosis it doubles to 92
Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
It is regulated by peristaltic movements. Then the pyloric sphincter will act as a valve at the junction between the stomach and duodenum, controlling the flow of chyme into the small intestine.
