DNAディーエヌエー発見はっけんなる
label.tran_page Will da Vinci's DNA be discovered?
500以上ねんいじょうまえDNA特定とくていその卓越たくえつ才能さいのう秘密ひみつ解明かいめい研究けんきゅう進行しんこうちゅうある
label.tran_page Research is underway to identify the DNA of Leonardo da Vinci, who died more than 500 years ago, and uncover the secret behind his extraordinary talent.

また墓所ぼしょ革命かくめい混乱こんらん破壊はかい直接ちょくせつDNA入手にゅうしゅ困難こんなん
label.tran_page However, since Da Vinci had no children and his tomb was destroyed during the chaos of the revolution, it is extremely difficult to directly obtain his DNA.
発掘はっくつ遺骨いこつ本物ほんもの自然しぜん研究けんきゅうしゃ作品さくひん手紙てがみなど自身じしん調査ちょうさ
label.tran_page It is natural that even if the remains are excavated, it is not known whether they are genuine, so researchers have no choice but to investigate items that Da Vinci himself touched, such as works and letters.

それでも500ねんサンプル有意ゆうい遺伝子いでんし情報じょうほう抽出ちゅうしゅつ高度こうど鑑定かんてい技術ぎじゅつ緻密ちみつ検討けんとうよう当然とうぜん
label.tran_page Still, it goes without saying that extracting significant genetic information from samples that are 500 years old requires advanced identification techniques and careful consideration.


今回こんかい実験じっけん注目ちゅうもくDNA抽出ちゅうしゅつ対象たいしょう
label.tran_page What should be noted in this experiment is the target itself from which DNA will be extracted.
生物せいぶつからだ直接ちょくせつ検体けんたいちが遠縁とおえん手紙てがみかれ素描そびょう綿棒めんぼう細胞さいぼうへん収集しゅうしゅうある
label.tran_page Unlike taking samples directly from the body of a living organism, for example, they tried to collect ``cell fragments'' from da Vinci's letters and his drawings using cotton swabs.
かぎりょうDNAふくくわ500ねん様々さまざま環境かんきょうさら
label.tran_page Not only does it contain only a limited amount of DNA, but it goes without saying that it has been exposed to various environments for 500 years.
それでも近年きんねん法医学ほういがく進歩しんぽめざ乾式かんしき湿式しっしき綿棒めんぼうはじサンプル採取さいしゅ方法ほうほう多様たようか
label.tran_page However, in recent years, forensic medicine has made remarkable progress, and sample collection methods have diversified, including dry and wet swabs.
かわ綿棒めんぼうでも十分じゅうぶん試料しりょう採取さいしゅできるとき研究けんきゅうしゃつよ希望きぼうかんちが
label.tran_page Researchers must have felt a strong sense of hope when they discovered that they could collect enough samples just by swabbing them with a dry cotton swab.


採取さいしゅサンプル細菌さいきん菌類きんるい動植物どうしょくぶつ動物どうぶつ由来ゆらいDNA
label.tran_page The samples obtained contained a variety of DNA derived not only from bacteria and fungi, but also from plants and animals.
注目ちゅうもくどういつ男性だんせいY染色せんしょくたい配列はいれつ一致いっちある
label.tran_page What is noteworthy is that the Y chromosome sequences of the same male matched.
自身じしんどうまだ断定だんていおなY染色せんしょくたい配列はいれつほか物品ぶっぴん一貫いっかん検出けんしゅつその人物じんぶつ特定とくてい
label.tran_page It is still not possible to say for sure whether it was Da Vinci himself, but if the same Y chromosome sequence is consistently detected in other items, it may be possible to identify him as the person.

DNA記録きろく遺伝いでんてき特徴とくちょう生物せいぶつしゅ種類しゅるい
label.tran_page In the first place, genetic characteristics recorded in DNA can even be used to determine the species of living things and the types of decayed trees.
研究けんきゅうチームサンプル混入こんにゅう可能かのうせい排除はいじょそこふくオレンジDNADNA注目ちゅうもく
label.tran_page While ruling out the possibility of sample contamination, the research team focused on the presence of orange tree DNA and wild boar DNA.
前者ぜんしゃつか庭園ていえん由来ゆらい後者こうしゃ使用しよう絵筆えふでひも可能かのうせいたか
label.tran_page The former seems to have originated from the garden of the Medici family, where da Vinci worked in Renaissance Italy, and the latter is likely associated with a paintbrush made from boar hair.

作品さくひん表面ひょうめん採取さいしゅDNAよう作家さっか痕跡こんせき
label.tran_page Even if DNA is collected from the surface of a work, it is essentially just a trace of the artist's touch.


同様どうようY染色せんしょくたい男子だんし系統けいとう調しらなか注目ちゅうもくE1b1集団しゅうだんすなわちある
label.tran_page While researching the lineage of males with the same Y chromosome as da Vinci, what caught our attention was a group called "E1b1", or a haplogroup.
これ全体ぜんたい214パーセント遺伝いでんがくてき1頻度ひんどたか
label.tran_page This corresponds to 2 to 14 percent of the total, but genetically speaking, anything over 1 percent is considered high.


本稿ほんこう割愛かつあいおなぞくどうその人物じんぶつ直系ちょっけい血縁けつえんいな一致いっちかぎ
label.tran_page Although I omitted this article, whether or not a person belongs to the same haplogroup does not necessarily correspond to whether or not that person is a direct blood relative.

それでも父親ちちおや子孫しそん採取さいしゅサンプルおなDNAふくこの研究けんきゅういっぽまたいっぽ前進ぜんしんある
label.tran_page Still, if samples taken from descendants of da Vinci's father contain the same DNA, this is a step forward in this research.hshsj
