During DNA replication, one of the new strands of DNA is synthesized continuously, while the other is synthesized as a number of separate fragments of DNA that are subsequently linked. Why does this occur? Option 1a) replication starts at many points on the chromosome Option 2b) replication can only start at one place on each strand of DNA Option 3c) RNA primers only anneal to one of the parental strands of DNA Option 4d) DNA polymerase III only synthesizes DNA in the 3' - 5' direction Option 5e) DNA polymerase III only synthesizes DNA in the 5' - 3' direction A piece of double-stranded DNA consists of 18 nucleotides. How many codons would the first-formed mRNA transcript have? Option 1a) 18 Codons Option 2b) 9 Codons Option 3c) 6 Codons Option 4d) 3 Codons
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
