Question
PLEASE i NEED THE ANSWERS
1.Genome sequences contain information about ancestry and evolution, and so comparisons among genomes can reveal how different species are related. Analysis of the similarities and differences in protein-coding genes and other types of sequence in the genomes of different species is an area of study called BLANK . Sequences that are similar in different organisms are said to be BLANK.
2.
What highly repetitive sequence of DNA is essential for the attachment of spindle fibers to the centromeres during cell division?
LTR elements
LINEs
Alpha satellite DNA
SINEs
3.Major evolutionary changes can be accomplished only by the acquisition of whole new genes.
True
False
4.Any number of sequences of sequence arrangements that indicate the likely function of a segment of DNA is called what?
Sequence motif
Sequence assembly
Genome annotation
Shotgun sequencing
5.What DNA sequencing method is it when the sequenced fragments do not originate from a particular gene or region, but from sites scattered randomly across the molecules?
Shotgun sequencing
Sequence motif
Sequence assembly
Genome annotation
6.Describe one example of a sequence motif.(SHORT ANSWER)
A.LTR elements
B.LINEs
C.Alpha satellite DNA
D.SINEs
Explanation / Answer
1. Analysis of the similarities and differences in protein-coding genes and other types of sequence in the genomes of different species is an area of study called Orthology . Sequences that are similar in different organisms are said to be paralogy.
2. What highly repetitive sequence of DNA is essential for the attachment of spindle fibers to the centromere during cell division?
