Summary Introduction

To review:

The given blank space in the statement, “The physical position of a gene on a chromosome is called _______. Alternative forms of a gene are called _______. These alternative forms of genes arise as ___________, which are changes in the nucleotide sequence of a gene.”

Introduction:

Gene is the biological unit of heredity. These are present on the chromosomes inside the nucleus in the eukaryotes. The DNA (deoxyribonucleic acid), in turn, is present in the genes. Genes are always present in two copies for a particular trait.

Explanation of Solution

A gene is made up of three DNA bases (example, AUG, TGG, GCG, ACT), which codes for a single amino acid. These triplet bases are present on the DNA and are known as codon when present on the mRNA (messenger ribonucleic acid). The place or spot where genes are present on the chromosomes is called locus. A locus marks the physical position of the gene on the chromosome.

The multiple forms of genes are known as alleles. They arise due to a mutation in the nucleotide sequence of the genes. These alleles are inherited from the parents, who contain either homozygous or heterozygous forms of these alleles. These alleles give variation to the newly formed organism as a result of reproduction. The changes in the sequence of the nucleotides or the replacement/removal of a base pair result in a mutation in the nucleotide sequence.

Conclusion

The physical position of a gene on a chromosome is called a locus. Alternative forms of a gene are called alleles. These alternative forms of genes arise as mutation, which are changes in the nucleotide sequence of a gene.

10. Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together. Once you are satisfied, staple or tape the amino acids in place and label the bond that you formed between the two R groups. - Polar covalent Bond - Red - Non polar Covalent boND- yellow - Ionic BonD - PINK Hydrogen Bonn - Purple Hydrophobic interaction-green O=C-N H I.

Find the dental formula and enter it in the following format: I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format) Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
