Answer:
295
Explanation:
Antibodies (also known as immunoglobulins) are immune system-related proteins that circulate in the bloodstream in order to recognize pathogenic harmful substances (antigens) and neutralize them. An antibody consists of two immunoglobulin heavy chains and two immunoglobulin light chains. There are two types of immunoglobulin light chains: 1-the kappa (κ) light chain, which is encoded by the immunoglobulin κ locus; and 2-the lambda (λ) light chain, which is encoded by the immunoglobulin λ locus. The immunoglobulin light chain is a multidomain protein composed of two domains: 1- the N-terminal variable (V) domain and 2-the C-terminal constant (C) domain. V(D)J recombination is a type of somatic rearrangement process by which T and B cells can assemble different gene segments, which are referred to as variable (V), diversity (D) and joining (J) gene segments. In the question above the number of possible genomic recombination events between immunoglobulin gene segments can be calculated as >> (5 x 35) + (4 x 30) = 295.
Question:
Trudy made this Venn diagram comparing interphase and cytokinesis.
Which statement belongs in the region marked X? (image attached)
Answer options:
- Is the longest stage
- DNA is copied
- The number of nuclei doubles
- The number of cells doubles
Answer:
- The number of cells doubles
Explanation:
Cytokinesis describes the splitting of the cytoplasm after mitosis. During interphase, the DNA is replicated. During mitosis, the DNA condenses into chromosomes, and the chromosomes are aligned and separated to opposite ends of the cell. During cytokinesis, the cell separates into two daughter cells.
Two intermediates of the sterol biosynthesis pathway, isopentenyl diphosphate and dimethylallyl diphosphate, are used by archaea in the biosynthesis of isoprenoids. Isoprenoids are organic compounds <span> which play widely varying roles in the physiological processes of plants and animals.</span>
Answer:
Chromosomes are like a ball of yarn in the sense that there are multiple components that make up the structure. Genes can be in similitude of the smallest threads in the yarn and when a multitude of genes are put together they make a DNA strand or a long, thick thread of yarn. Lastly, when DNA is twisted together, it becomes bundled together, making a chromosome or a "ball of yarn".
