The nucleus is replicated , therefore a copy of DNA is made
Hydrogen bonds are weaker than covalent bonds.
Answer;
C) ATP
Explanation;
-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions (also referred to as the "dark" reactions).
-The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.
-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
Answer:
The correct answer will be option-A
Explanation:
The practice of marriage is practised in every culture which is associated with the union of the boy and a girl to which they are committed to spending a life-long relationship.
The studies on the preferences shown by the woman who has to get married have to look for the boys who are career-oriented which could provide a good earning to feed them and their family and fond of children to establish a family which will help develop the stronger relationship between them.
The girls ignored the attractiveness feature of their spouses as in a long term relationship attractiveness does not matter because of the feeling of love and strong bond between them.
Thus, option-A is the correct answer.
Answer:
these statements are true
B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence
D) Missense mutations always change the amino acid sequence encoded by a gene
E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.
Explanation:
B) insertion or deletion of nucleotide in coding region of DNA can change the amino acid sequence encoded.
D) missense mutation means that the change in nucleotide sequence resulting in change in amino acid sequence encoded by gene.
E) A mutation may alter the promoter of a gene, thereby affecting the rate of transcription.
