Answer:
A. 1' ... 5'
Explanation:
The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.
Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.
Answer:
S phase
Explanation:
S phase is the second phase of interphase (longest phase where cell grows and replicates it's DNA and does it function. It is broken up into smaller sub phases). S phase is the synthesis phase. During this phase chromosomes are replicated ( The DNA is copied).
Mutations can be somatic or inherited. Somatic mutations are mutations that occur in a single body cell, so only tissues derived from mutated cell are affected. Somatic mutations are not inherited. On the other hand, inherited or germline mutations occur in gametes (egg cells and sperm cells) and are passed onto offspring. As a result of these kind of mutations each cell in the organism is affected.
Somatic mutations: BRAF and KRAS gene.
Inherited mutations: FRG2 and BRCA1 gene.
Answer:
<em>The correct option is A) recasting</em>
Explanation:
Recasting can be described as a method for teaching a language in which the instructor corrects the learner by repeating the error back in a corrected format. In this way, the learner recognizes where he made a mistake and tends to understand it.
Parents often use the technique of recasting to teach their children new complex words or to correct them if they speak any wrong word.
