1 answer:

8 0

<span>Symbols for lipids is C and H.
It also contains Nitrogen and phosphorous. DNA or RNA their symbol is C, H, O, N, P. Protein contains both sulfur and selenium which are C, H, O, N, P. Proteins are subunits of amino-acids.
Proteins can be carriers, signaling structural and also immune responses. They are made of the nucleus.
Lipids are hydrophobic and are naturally found in the body to mean that they don't mix with water reason being they are non-polar. Lipids make up phospholipids bilayer.
DNA is supercoiled, and their backbone which is made up of phosphate and sugars groups.</span>

During transcription the DNA base sequence is transcribed into a complementary mRNA sequence. A codon table like the one shown b

DIA [1.3K]

Answer: Option B) No, even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.

Explanation:

Since the triplet codon ACG codes for the amino acid threonine, so also ACA codes for threonine, the single base change of Guanine (in ACG) to Adenine (ACA) is insignificant due to the degeneracy of the genetic code.

Thus, the sequence still codes for the same amino acid, so no change in phenotype will occur

Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?

daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

monomer/glucose glycosidic bond branching

1.starch α glucose 1-4 and 1-6 branch and unbranced

amylose 1-4 unbranched

amylopectin 1-4 and 1-6 branched

2. dextran α glucose 1-6 branched

3. cellulose β glucose 1-4 unbranched, linear

4. glycogen α glucose 1-4 and 1-6 branched (shorter

branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.
