Summary Introduction
To review:
The reason for difficulties encountered in locating protein-coding regions in a genomic sequence.
Introduction:
The amino acids are building blocks of proteins. Protein encoding is initiated when a stretch of DNA (deoxyribonucleic acid) encodes genetic information for the amino acid sequence specific for the future protein. This is followed by the transcription process, in which this genetic information is transferred to mRNA (messenger ribonucleic acid) from any of the two strands of DNA. Once mRNA is formed, it undergoes processing steps like splicing, tailing, capping. This removes introns or non-coding sequences. Ultimately, the final step is protein synthesis from coding sequences of genome called translation occurs. Locating anonymous protein-coding regions in a genomic sequence can lead to ambiguity.

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.

Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
