Summary Introduction

a.

To determine:

The sequence that is genomic fragment and the sequence that is cDNA fragment.

Introduction:

The short sequences of DNA that are obtained from the genome of an organism are termed as genomic fragments. The fragments of complementary DNA that are stored in the cDNA library are termed as cDNA fragments.

Summary Introduction

b.

To determine:

The RNA like strand of the genomic fragment and to represent vertical lines between exon and introns.

Introduction:

The genetic material of eukaryotes is composed of two parts. These are introns and exons. The coding parts of DNA that encode for amino acids are termed as exons. However, the non-coding parts that do not encode for amino acids are termed as introns. The prokaryotes are composed of only the exons. They do not contain introns.

Summary Introduction

c.

To determine:

The sequence features important for RNA splicing that is missing.

Introduction:

The mRNA contains both introns and exons. The exons encode for the amino acids while the introns do not encode for amino acids. They introns inhibit the synthesis of proteins. The process by which all introns are removed from mRNA is termed as RNA splicing.

Summary Introduction

d.

To determine:

The amino acid sequence of protein product of the gene.

Introduction:

The mRNA consists of many bases. A collection of three bases that has the capability to code for a particular amino acid is called codon. Codons are present in the mRNA. These codons attach with the anticodon part of tRNA to synthesize amino acid. The anticodon part of tRNA is complementary to the codon part of mRNA. As a result, these two join together and undergo a translation process to produce amino acids.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
