Answer:
1) option A - 5' TAG CTG GTA 3'
2) Option C - regulates which materials enter and leave the cell
3) option B - heredity information
Explanation:
For question 1) The complimentary strand will read in opposite direction 5' to 3', and will have each base replaced by its specific base pair:
Adenine (A) replaced by Thymine (T)
Guanine (G) replaced by Cytosine (C)
Thus, the complimentary strand of 3' ATC GAC CAT 5' read as 5' TAG CTG GTA 3'
For question 2)
Cell membrane is a flexible membrane made up of proteins and lipids, and is role is to
- select the materials absorbed by the cell
- protects the cell
For question 3)
DNA stores hereditary information along its sequence in form of genes, that are passed down to offsprings, and determine their traits/behavior
I think the answer is a or c
Answer:
The correct answer will be- newly synthesized polypeptide
Explanation:
The process of translation or the synthesis of proteins takes place in the ribosomes which provide a site for the synthesis of polypeptides. The ribosomes are made up of two subunits: small and large subunits which provides slots namely A, P and E sites.
The tRNA brings specific amino acid corresponding to the codon of the mRNA and during elongation, the tRNA molecule moves from A site to P site to E site.
The component which exits the exit tunnel is the formed polypeptide chain which exits from the E or exit site.
Thus, the newly synthesized polypeptide is the correct answer.
Enzymes and acidic juices in the stomach, which break proteins down into smaller molecules, is known as proteolytic enzyme.
Proteolytic enzyme (also known as protease) is any group of enzymes that break down the long chainlike proteins molecules into smaller molecules (peptides) and later into amino acids. In the stomach, protein digestion takes place. The three main proteolytic enzymes; pepsin (produced by the stomach), and trypsin and chymotrypsin (produced by the pancreas) breaks down proteins into polypeptides which are eventually broken down into amino acids by several exopeptidases and dipeptidases.
