Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
Awnser : C Lacks genetic variation
Explanation : The major disadvantages of asexual reproduction are: Lack of diversity. Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.
Answer:
The correct answer will be:
1. Mutualism
2. Competition
3. Commensalism
Explanation:
In an ecosystem the organism interacts with each other in one of the following ways:
1. <u>Competition</u>- interaction occurs when two or more than two species depend on the same resources, sharing the same habitat and niche. These species will fight for the resources and both will be negatively affected.
2. <u>Commensalism-</u> interaction takes place when one organism is benefited while the other is neither harmed nor gained. For example- the interaction between Remora fish and large fish in the ocean.
3. <u>Mutualism</u> -occurs when the species are dependent on each other for the resources and both benefits each other. For example- the plants and birds co-evolved benefiting each other like animals helps in pollination and plants provide nectar to them.
Thus, the selected options are the correct answer.
Answer:
Dimers, trimers, and tetramers are, for instance, oligomers composed of two, three, and four monomers, respectively. In biochemistry, an oligomer usually refers to a macromolecular complex formed by non-covalent bonding of a few macromolecules like proteins or nucleic acids.
