Please answer all part of the question

(3.2) I have a sam file called “sequences.sam” and a genomic feature file called “features.bed”. I would like to annotate all the sequences in the sam file with the bed file (overlapping features). Can you write down the commands needed using samtools and bedtools?

(3.3) Can you obtain at least two mRNA isoforms of TP53 from NCBI or other online resources? Generate a bed file containing both, color them differently and visualize them on UCSC genome browser? Take a screenshot of the visualization
