Which of the following is not true about scaffolds in a genome assembly? Group of answer choices Every base position in a scaffold has a known nucleotide sequence. Scaffolds are made up of contigs. Scaffolds may correspond to an entire chromosome arm or may be smaller. The creation of scaffolds requires a genetic map.

Consider the following segment of DNA, which is part of a linear chromosome: LEFT 5’.…TGACTGACAGTC….3’ 3’.…ACTGACTGTCAG….5’ RIGHT During RNA transcription, this double-strand molecule is separated into two single strands from the right to the left and the RNA polymerase is also moving from the right to the left of the segment. Please select all the peptide sequence(s) that could be produced from the mRNA transcribed from this segment of DNA. (Hint: you need to use the genetic codon table to translate the determined mRNA sequence into peptide. Please be reminded that there are more than one reading frames.)

An explorer discovers a strange new species of plant and sends some of the plant tissue to a geneticists to study. The geneticist isolates chromatin from the plant and examines it with an electron microscope. She observes what appeared to be beads on a string. She then adds a small amount of nuclease, which cleaves the string into individual beads that each contain 280 base pair of DNA. After digestion with more nuclease, a 120 base pair fragment of DNA remains attached to a core of histone proteins. Analysis of the histone core reveals histones in the following proportions. On the basis of these observations what conclusions could the geneticists make about the probable structure of the nucleosome in the chromatin of this plant?
